Good readings, easy to use, sensitive to radio interference.

Very easy to use and gives accurate readings when I poured a deep bowl of ice water tested. I had a strongly fluctuating fridge/freezer combination, which I registered for about 5 days. When I plotted this result (Excel) I saw that the problem got progressively worse as the ups and downs increased with each cycle. In the mini-fridge, the noise sensor displayed numbers off the scale. The same is in the small freezer in the utility room. So your chances of success are just random based on the RF…

Pros
  • Power supply: AA batteries (included) or 9V adapter (not included)
Cons
  • Can't remember but there was something

Excellent data logger for the price but sensitive to electrical noise

Generally satisfied with the data logger. I've tested it quite extensively, the battery lasts a long time. It's great to have all the data in one .txt file that I can export to Excel. Certainly unbeatable for the price. Checked the thermocouples in the ice bath, found to be well calibrated. The only caveat is that I ran some tests with quite a bit of electrical noise (huge current transformers produce 200 amps) and this seemed to skew the data. Temperature jumped up and down 20 degrees - not…

Pros
  • Sample rate: programmable from 1 second / LCD size: 47 x 104 mm
Cons
  • unreliable

Suitable for data logging

I use this to monitor the efficiency of my boiler system. 4 channels is good. I tested in an ice bath and boiling water. Using the offset function, I was able to calibrate all channels to within a few tenths of a degree, according to the declared properties. I also compared it with my meter. The device creates a CSV file during registration. I was able to take the generated CVS file and import it into OpenOffice to show the temperatures inside and outside the boiler and each zone to calculate…

Pros
  • K Temp. range: -200 to 1370 °C, -328 to 2498 °F / Resolution: 0.1 °C/°F / Accuracy (at ambient temperature 18~28 °C): ±(0.3 % of reading + 1°C)
Cons
  • So far so good
