Aivica Digital Dual Channel Temperature Thermometer With Two K-Type Thermocouple Probe, Backlight LCD for K/J/T/E/R/S/N Thermocouple

Works and seems reasonably accurate, better then I expected for $22. When measuring body temp one probe is about 0.5 degrees Fahrenheit off while the other is about 1.5 degrees off. Not at all bad for such a cheap device actually way better then most common thermometers. I do not really have a good way to check the accuracy at high or low temps, but should be close enough for what I would use it for.

The meter is good and seems accurate. But! the dang thing turns off too quickly. I need to get a meter that i can keep on or adjust the time-out duration, especially when I am trying to monitor a critical temperature reading. I am trying to monitor the input and output water temp on a CO2 laser while it is firing and this meter keeps turning off - it is annoying. If you want to monitor a constant temp on something be prepared this is not that meter.

Rated accuracy is +-2.5°C.Using an ice bath made with RO water, filled with RO water, it shows 1.3 °C on both included probes, so the precision is good, which is most important to me.My IR probe showed -1.2°C, and TDS probe showed -5°C. Since none are calibrated, who knows, but my bet is that -1.2 °C is most correct. TDS was measured at 44, so some freezing point depression probably is correct. If -1.2°C, then the error is +2.4°C, slightly under the rated +-2.5°C. I'll live with that uncertainty, not buying a NIST calibrated thermometer to check.Getting different probes tomorrow, so we'll see.

I tested the accuracy - it is within .5C that it is very good for his class.I use primarly to water temperature, and it is what I want. I bought sturdier probes for my usage, since the ones that come with the thermometer are and damageable.

I've found this to be very accurate with the $15 sensor.
