Lascar - ELUSB2 EL-USB-2 Humidity, Temperature and Dew Point USB Data Logger

I have owned the Lascar temperature and dew point datalogger for 2 weeks now. I had a problem with the driver when I first installed it. It kept dropping out and not reconizing the logger. After reinstalling it a couple of times it seems to be working fine for now. Maybe the software needs to be updated by the company.Anyways this datalogger is very usefull. I am a service tech for a major company. I find it very usefull to check temps in refrigerators to see if they are working properly(maintaining proper temp in both freezer and refrig). The unit if very accurate.

This little gadget rocks. Self contained sturdy unit attaches to pc. You tell it how often you want readings and when to start. Used it in my attic and different rooms of the house to watch temperatures and humidity during a hot summer. Helped to decide on Central Air settings and whether to add insulation or an attic fan. Produces nice graphs. Only basic computer skills required. Long battery life and lots of memory for readings.

The product looks fine but i used the battery only for 2 days and when i tried to setup for other reading , it asked me to replace the battery.Its not fair. Very disappointed !

I use this at work to watch for Temp and Humidity fluctuations while working on and calibrating lab equipment. The software alllows me to set the number of data points per minute and plots the Trend Lines for the Temp and Humidity. I don't need super accuracy in the actual readings because I am more interested in the amount/rate of change over time.This Lascar EL-USB-2+ and software does exactly what I need it to do. If you need really accurate measurements, get a Wet Bulb/Dry Bulb thermometer set. Very accurate Temp and % R.H., but heck of a lag time!!

Product is working exactly as designed. Very pleased with this purchase. Only negative is that the unit does not come with a software CD anymore so you have to go to the company website to download the latest software. That's fine except the website was off-line the first couple of days I tried so couldn't set up the device. Searching around on the internet I found a software site that had latest s/w and installed it. Software seems a bit basic; but works well and I've had no problems running it on XP/SP3. Also have had no problems importing the CSV file into OpenOffice Calc. My unit has been monitoring temp/humidity in a ventilated enclosure located by a crop field for last week plus so appreciate the weather protection of the unit. The data collected so far is on par with nearby airport readings. While the LCD version might be useful for some I didn't see a need for it. If you are going to leave the unit in place for days at a time (I check/download/reset once a week) there's no reason to pay the higher price and shorter battery life.

The dataloggers appear to be working very well after a week's use. The software was easy to find on the manufacturer's site, and install, and the devices themselves are straightforward to set up and use: very plug-and-play.

I use this datalogger mainly to monitor long term temperature in my attic. It is very easy to use. I have used it for other purposes and have noted that the RH value is way off (~20%). It will trend correctly but the absolute value is wrong. BTW, I'm not talking about when I use it in the attic, but rather in normal locations where I have access to pretty good RH data. I should have returned it, but I didn't.I would investigate other options before buying again.

Awesome Price!
