Accuracy

±0.25°C from -20° to 0°C (±.45°F from -4° to 32°F)

±0.2°C from 0° to 70°C (±0.36°F from 32° to 158°F)

Resolution

0.01°C (0.018°F)

Drift

<0.1°C (0.18°F) per year

Water Detection

Water conductivity level of 100 µS/cm or greater necessary for reliable detection of water. Deionized water or water below 100 µS/cm may not be detected.

The water conductivity circuit may not reliably detect water that has frozen around the electrodes, i.e. below 0°C (32°F).

Memory

96,000 measurements

Battery

CR2477 3V lithium, user replaceable in MX2203, non-replaceable in MX2204

Battery Life

3 years, typical at 25°C (77°F) with logging interval of 1 minute and Bluetooth Always On in software.

5 years, typical at 25°C (77°F) with logging interval of 1 minute and Bluetooth Always Off or Bluetooth Off Water Detect in software.

Faster logging intervals and statistics sampling intervals, burst logging, remaining connected with the app, excessive downloads, and paging may impact battery life.

Time Accuracy

± 1 minute per month at 25°C (77°F)
