In what environment does this data logger operate?

This data logger operates in indoor, outdoor and underwater environments.

What measurements does this data logger support?

The MX2203 data logger supports the following measurements: Temperature and Water Temp

Temperature Sensor (MX2203 and MX2204)

Range

MX2203: -20° to 70°C (-4° to 158°F) in air; -20° to 50°C (-4° to 122°F) in water

MX2204: -20° to 70°C (-4° to 158°F) in air; -20° to 50°C (-4° to 122°F) in water, maximum sustained temperature in water 30°C (86°F)

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

Response Time

MX2203: 17 minutes typical to 90% in air moving 1 m/s, unmounted;

7 minutes typical to 90% in stirred water, unmounted

MX2204: 15 minutes typical to 90% in air moving 1 m/s, unmounted;

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 MX2303, non-replaceable in MX2304

Battery Life

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

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

To ensure proper battery installation, see Battery Information for detailed instructions on replacing the battery in the MX2203 logger.
