Digital 4 Channel Thermocouple Thermometer Temperature Recorder Data Logger AZ Instruments Multi Channel K Type Thermometer Thermocouple Reader with 8G SD Card 2 Bead Type K-Thermocouple Probe

This works well in my kitchen. It has many applications.

Works great for displaying and saving (to the included 8GB SDHC memory card) four(4) channels of thermocouple temperature data. Then you need a USB SD-card reader (or some other mechanism) to get the data into your PC. No special software required. The resulting text files are easy to read, and include date, time, and 4 channels of temperature data. Having the 2x2 temperature display, instead of a 1x4 list, really helped in our application. As others have indicated, the readings tend to jump around a bit (perhaps up/down 3 degrees C) in the presence of electrical devices, a design defect which ought to be corrected. Others have complained about the instructions included, perhaps they have been upgraded, they weren't perfect but they were pretty good. We were up and running in short order, and this device paid for itself on the first day of usage. You may as well also purchase "9V 1.5A AC/DC Power Adapter for Arduino, Tbuymax UL Listed Center Positive 5.5mm x 2.1mm Power Supply..." to save on batteries and enable long-period usage. Overall a good product deserving of your consideration.

I'm using to record temps in my burnout kiln to figure out what is going on in my flasks. I bought some fiberglass insulated thermocouples so I can track flasks as they go up to 1350F. It tracks great, it's accurate (I always have a control), and outputs an easy to use flat file. I would recommend this and I will actually probably buy another one. I went from 0 to 4 inputs and now I kinda want 8 :P

It's a great option for those non critical measurements that require precise data. Not that this unit is not accurate. It's easy to use and easy to retrieve the data. I don't know how long the batteries last and is my only draw back when I need to run the logger for hours at a time, but so far I haven't had any problems.

The menu system to set up the settings is not good, and the screen shuts off while it's logging so you can't check what the temps are without stopping it logging. Also, it doesn't come with the 120v adapter and as far as I can tell the adapter is not available anymore. So you're stuck with using battery power. Which isn't the end of the world; the batteries do last pretty long while using it. But it does drain the batteries dead while sitting on the shelf turned off, so remove them when you're done using it. But it does work, and as far as I can tell it reads accurately. So if you can get past the clunky interface and battery only operation, it's a good little unit.

I'm using this to monitor the efficiency of my boiler system. The 4-channels are good. I tested in an Ice bath and boiling water, Using the offset feature, I was able to calibrate all the channels within a couple of tenths of a degree of each other well within the advertised specification. I also compared it to my fluke meter. The unit generates a CSV file when logging. I was able to take the generated CVS file and import to OpenOffice to plot the temperatures in and out of the boiler and each zone to calculate the thermal energy being used by each zone. I was using this to adjust the water flow speed to ensure that the water spent enough time in the pipe circulating in each zone to properly heat my floor. Pros: Uses standard k-type thermal couplers. The display is easy to read each channels temp Uses a standard power supply 9V 1.5A Center Positive 5.5mm X 2.1mm connector Logs to a CSV file, configurable sample rate Cons: The display turns off when logging mode is operational While you can figure out the manual, its hard to read poorly translated English The probes that come with the unit are very short (glad the K-type probes are cheap) All in All, I do recommend this unit.

Briefly: I purchased this to log temperature data, every five minutes, just the temperatures. This is simple enough, I am not asking too much. But this device was not writing data to the SD Card as it was supposed to. So, I sent a message to the manufacturer, but they just basically told me to "read the manual". No problem, I read technical manuals, I write them, I design products that have manuals, I know the drill. As it turns out, I had already read and re-read in detail their manual before contacting them, and I did not need them to tell me how to set up their device. I had already done so. The problem was that they did not listen to the problem, so let me state it again clearly: THE DEVICE IS SET UP PROPERLY. THE SD Card has been properly formatted IT TAKES DATA BUT ONLY APPENDS THE DATA TO THE SD Card FOR A WHILE. This could be a few hours, or just a few minutes. THEN DATA LOGGING STOPS RANDOMLY. For example, here is a set of data that was supposed to last a full day: MN/AT date time int 1ch 2ch 3ch 4ch unit AT 2023-07-17 17:11:12 5m 41.6 43.1 30.5 C AT 2023-07-17 17:16:12 5m 41.6 43.0 31.4 C AT 2023-07-17 17:21:12 5m 41.6 42.9 31.4 C AT 2023-07-17 17:26:12 5m 41.6 42.9 31.9 C AT 2023-07-17 17:31:12 5m 40.9 42.2 31.3 C AT 2023-07-17 17:36:12 5m 40.2 41.2 31.3 C AT 2023-07-17 17:41:12 5m 40.1 41.2 31.3 C AT 2023-07-17 17:46:12 5m 39.1 40.1 30.6 C AT 2023-07-17 17:51:12 5m 37.7 38.6 29.3 C AT 2023-07-17 17:56:12 5m 36.9 37.9 29.3 C NOTICE that it is set up correctly and taking data every 5 minutes, but then stops logging after only 10 time points. Infuriatingly, if you repeat this, exactly, without changing any settings, it will log for example: 3 time points, then 2454 points when you restart it, then 12, then a few hundred... and on and on like that, just stopping randomly, with random sampling periods each time before it quits. So, the company can either send me another one THAT THEY HAVE TESTED AND THAT WORKS PROPERLY AS ADVERTISED, AT THEIR EXPENSE, or I will just take the loss and advise everyone: >>>>>>>>>>>>>>>>>>>>> DO NOT BUY THIS PRODUCT <<<<<<<<<<<<<<<<<<<<<<<<<

I purchased this to take pipe temp readings on a problem refrigeration job. With 3 probes connected I quickly found issue I was having. I let this machine log every 30 seconds for 48 hours and it worked flawlessly. I have no complaints about the machine. The instruction book is hard to read, the print is so small and my eyes can't read the fine print anymore. Had to print off manual from internet to make it legible. Seems typical with manuals now a day. Would recomend if you need a temperature data logger.

il termometro funziona molto bene

Producto de buena calidad, tal cual la descripción 👍🏻

Ich kann den Logger uneingeschränkt empfehlen. Ein Kunde schreibt, die Anzeige geht in Rekorderbetrieb aus. Sie lässt sich aber aktivieren, wenn man die Bedienungsanleitung liesst ;-) Per default ist sie zum Energiesparen aus. Das macht auch Sinn. Die Bedienung ist auch nicht so schwer wie manche schreiben. Ziemlich selbsterklärend

Le produit fonctionne comme attendu. Pour une mesure toutes les 10 s, le produit consomme un set de 4 piles AA en environ une semaine. Donc, pour des mesures longues, comme recommandé par le manuel fourni, c'est mieux d'utiliser un adaptateur 9 V marqué comme optionnel. Sauf que c'est pas indiqué quel type de connecteur et quelle polarité. Je viens d'essayer avec un connecteur 5.5 / 2.1 mm, avec polarité + au centre et ça marche.
