## Description

Dual Channel K-Type Thermocouple Thermometer with Two Probes and Backlit LCD: desertcart.com: Industrial & Scientific

Review: Surprisingly good - UPDATED - Right from the box I ran through the settings of probe type (=K), and Temp scale (=F) - very simple to do, and all settings remain as they were at last power-off. The room temperature initially read 73.4F and 79.1F, but after 30 seconds or so, they settled down to readings of 70.1F and 70.1F. Over the next half an hour, one reading or the other would briefly move up or down by +/- 0.1 or 0.2, but always returned to 70.1. During this time, I cycled the power every few minutes to see how the meters started back up. There was only a second or two of settling time with each power-up. I left the probe ends in place, close together and weighted down to the floor by a book. Handling the meter body had no effect on the readings. Unplugging and switching the probes made no difference. Comparing to my trusted Fluke 80T probe I have used since 1982 or so (and was last calibrated in 2007), the Fluke measured room (floor) temperature reading is 70.0F. Based on my experience with thermocouple probes supplied with various multimeters I own , this is extraordinarily stable and precise, as well as accurate at at least one point. This result is not something anyone should expect from a mass-produced thermocouple thermometer - especially an inexpensive one. Probably I was just lucky - but at least it shows that such performance is possible from this instrument. I plan to make accuracy tests with an ice bath and with boiling water, and tracking precision tests with refrigerants such as CO2 and with a hot air gun. I will use a variety of probes as well as the ones supplied. I think it highly unlikely that the two probes will track so perfectly over a wide range of temperatures, but this single point test is encouraging. I will update this review after I perform further testing. **** UPDATED**** I did some further testing, using the probes supplied. I twisted the probe ends together so they would be in the same environment. In an ice water bath The two probes read 33.8F and 34.1F after stabilizing for about 2 minutes. In my home freezer (set for -5F), The probes read -5.1F and - 4.8F. In boiling water, they stabilized at 211.7F and 211.1F. I tried to read my oven, set to 300F, but I couldn't get a stable reading. It turns out that the oven cycles on and off fairly frequently, and the temperature swings high, then low as it does and the probes can't keep up. Manufacturing variations result in the sensing beads on the two probes being visibly different in size - about 2:1 in diameter. The larger bead is much slower to settle than the smaller bead. As the temperature is swinging up and down, the difference in readings becomes large, only settling once the temperature becomes constant for a minute or so. Probably by selecting two thermocouples from the same manufacturer's batch that have nearly identical junction beads, the probes would track well. I ordered a set of ten probes to use in that way.

## Questions & Answers

**Q: Would this work for a forge?  I presume the wires would not survive flames though?**
A: They make ceramic insulators with two holes that slide down the wires. We use them on reheat furnaces in the steel industry. You need a screw in thermocouple long enough to go past the insulation. Your wires will be outside. This is assuming you don’t have a coal forge and bellows. If your 1830s blacksmith forget new tech and eyeball the color.

**Q: How do you turn off auto power off? The instructions are unclear.**
A: Press the HOLD button and then press the POWER button

**Q: Will device read to 2000 F? I have the appropriate K type thermocouple for a foundry furnace (proper insulators, wire, mounting blocks).**
A: It will read everything within the range. I can't remember the range.

**Q: Can you manually calibrate this using ice water and boiling water?**
A: Interesting idea, calibrating an instrument that can use a bunch of different alloy TCs. 

I suppose one might expect to calibrate the basic A/D conversion portion of the circuit, and perhaps a portion of the cold junction compensation, depending on how that’s designed; there are commercial ICs that do the job, but they depend on careful design of the chip placement and board design, and all of ‘em that we’ve used over the years are specific to a single type, J or K or whatever. 

Calibration of the rest of the design, specifically the portion that interprets the input from the TC and generates a number that can be displayed, that’s a whole ‘nother ballgame - the NIST tables are a glory to be seen, and AFAIK there is no reason to ever expect to tweak the 7 (or 9 or 11 or more) degree polynomials that describe a pristine alloy junction in a perfectly designed and constructed circuit. 

If the firmware is set up to allow tweaks of this sort (we’ve seen some badly intentioned equipment that does just that) you’re going to be out of luck - any procedure within reach of the ordinary well intentioned consumer is doomed to failure. 

An ice bath and boiling water is a good example; the minimum lab grade equipment needed, triple point cells and such, isn’t easy to obtain or use, and calibration over small T ranges isn’t useful in the general sense. 

When we were doing a precision design, we had access to triple point cells with carefully chosen metallic alloys, and could check calibration of (for example) a shipment of type J or K extension cable over ranges of several hundred degrees C. 

It was a PITA, too; the interesting stuff we did used precision platinum RTDs from NIST (actually, originally from NBS around 1950 that cost several thousand $ each back then) with which we were able to calibrate our calibration equipment to 0.001 degrees C. 

All that got us with the equipment under design was the ability to guarantee that any two examples anywhere in the world would agree within 0.1 degree C over the three month calibration cycle. 

Measuring temperature precisely and accurately to a known standard spec is a lot harder than it seems like it ought to be, until you sit down an try to prove that what the display says is actually correct. 

Consider this piece of equipment to be useful to plus or minus several degrees F or C, take your pick, and you’ll be fine. For most uses, that plenty good enough.

(For medicine use a mercury fever thermometer, and enjoy the precision that an extremely limited range can get you at a fairly low price. But what does it mean? That’s a different issue, eh? Even the newer electronic fever thermometers are good enough, really. But the mercury ones are really, really good instruments, a rarity in temperature measurement that’s under appreciated…)

### ⭐⭐⭐⭐ Great For the Price
*by T***N on January 19, 2016*

I purchased this thermometer to take temperature measurements around the house and just to have a toy to tinker around with. I am not using it for any industrial or scientific purposes that require super high accuracy. If that's what you want, then you need to spend the money necessary to achieve that (i.e go buy a Fluke). You're simply not going to get that for $17. After I opened the box, I decided to test the accuracy, so I put a pot of water on the stove and brought it to a boil. I stuck the leads in the center of the pan (without touching the sides or bottom) and both leads read 209.1°F and stayed there. I checked the barometric pressure (since the boiling point of water varies with pressure) and I determined that the water in my area should boil at 211°F. So, I figure that this thermometer's accuracy is within 2°F to 2.5°F, which is good enough for me. Sure, I wish it was reading dead on accurate, but the good news is that both leads read exactly the same in the boiling water, so there's no variance at all there (like is the case with some cheap thermometers that give different readings on the different leads). Pros: Cheap Fairly accurate Both leads read exactly the same during the boil test (209.1°F). Nice buttons Decent build quality Does min/mean/max readings Has a hold function Can use almost any type of thermocouple (K, S, E, J, etc.. etc..) Cons: Inaccurate by around 2°F The backlight cannot be controlled, it only comes on for a few seconds after a button press. I would like the option to turn it on for as long as needed or for it to have a longer cut-off time. Has a cutoff of around 3-4 minutes (I didn't check exactly). Sometimes cuts off right in the middle of a reading which is annoying. Cannot be calibrated and you cannot create offsets (i.e. you can't do manual error correction by adjusting it to a known temp). Overall: The pros outweigh the cons and it's definitely worth $17. This thermometer is made in China and no other developed country would be able to produce a thermometer like this that retails for $17. So, all of us in the west should take advantage of China's generosity before they develop further and their people begin demanding 401K's, $40 an hour, full medical and dental, and pension plans like us Americans. It will happen at some point, so get while the getting is good.
