Rated 4 out of 5 by Myrran from Solid Logger (for the most part) I have bought roughly 10 of these over the past 8 years. We use them for monitoring the temperature and humidity of a control room for Concrete testing. For the most part these are solid units. I have had a couple that had the screens go out on them after 5 years or so and the plastic gets discolored when exposed to sunlight. One had the temperature go out and it only lets you calibrate it slightly from the original settings. That said these generally work great with those few exceptions. The program for the PC is easy to use and understand. I will continue to purchase these as needed.

Rated 4 out of 5 by dusty from works great. easy to use. had to guess where to get software to download data to but figured it out eventually. USB connection works easily, but I would now pay a little mre for a wireless download option

Rated 4 out of 5 by 1234 from Good for general monitoring We really like the OM-70 series for monitoring temperature and humidity during our testing. They work well and the software is easy to use. The only issue we have is that they will not stay in calibration in the lower 10 degrees C of the published range and there is no adjustment to correct this. We calibrate them to 10 C above the published low range and they work well there.

Rated 5 out of 5 by Andrew W from Works as promised These are great for measuring temperatures in a concrete cure room that we have for ASTM C511.

Rated 4 out of 5 by Kyle from Good value for a stand alone data logger I have bought these many times over the years and appreciate the updates to the user interface. The data loggers are very robust and accurate. I would give this a 5 star review if there was a version of the software that would also calculate Heat Index as part of the standard data output. Very useful for safety studies.

Rated 1 out of 5 by Hughmahn from NOT A PRODUCT YOU WANT TO PURCHASE!!!! OMEGA will not support this product. You have to send over $65.00 for the software to operate the product. DO NOT PURCHASE THIS PRODUCT!!!

Rated 4 out of 5 by Lorenzo from Reliable instrument Have one of this working for more than 4 years in a curing room in the middle of the Mojave desert. No problem at all.
