HOBO® TidbiT® MX Temp 400 (MX2203) and

Temp 5000 (MX2204) Logger Manua

21537-B

HOBO TidbiT MX Temp loggers measure temperature in streams, lakes, oceans, coastal

habitats, and soil environments. Housed in a protective boot, these rugged loggers are

designed for extended deployments in fresh or salt water at depths up to 400 ft (MX2203) or

5,000 ft (MX2204). The loggers use Bluetooth® Low Energy for wireless communication with a

mobile device and are equipped with an optional water detection feature that automatically

turns Bluetooth advertising off when the logger is submerged in water, thereby preserving

battery power. Using the HOBOmobile® app, you can easily configure the loggers, download

logged data to your phone or tablet, or automatically upload the data to HOBOlink® for further

analysis. You can also configure the loggers to calculate statistics, set up alarms to trip at

specific thresholds, or enable burst logging in which data is logged at a faster interval when

sensor readings are above or below certain limits.

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).

Wireless Data Standard Bluetooth Low Energy (Bluetooth Smart)

Logging Rate 1 second to 18 hours

Time Accuracy ±1 minute per month at 25°C (77°F)

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 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.

Memory 96,000 measurements

Select the power saving mode, which determines when the logger will “advertise” or regularly send out a Bluetooth signal for the phone or table to find via HOBOmobile. • On Next Logging Interval. Logging will begin at the next even interval as determined by the selected logging interval. • Bluetooth Always Off.

HOBO TidbiT MX Temp 400 (MX2203) and Temp 5000 (MX2203) Logger Manual • The actual values for the high and low alarm limits are set to the closest value supported by the logger. For example, the closest value to 85°F that the logger can record is 84.990°F. In addition, alarms can trip or clear when the sensor reading is within the specified resolution. This means the value that triggers the alarm may differ slightly than the value entered. For example, if the High Alarm is set to 75.

Drag the slider to the reading that will trigger burst logging or tap the value field and type a specific reading. In the example, the logger will switch to burst logging when the temperature falls below 32°F.

If wire is used to secure the logger, make sure the wire loop is snug to the holes. Any slack in the loop may cause excessive wear. • Periodically inspect the logger for biofouling if it is deployed in water and clean as described above.

Place the logger back in the protective boot, making sure the ridge in the logger case slides into the groove on the inside of the boot. a. Spread a small dot of silicone-based grease on the Oring with your fingers, making sure the entire O-ring surface is completely covered in grease. b. Place the O-ring on the cover and clean off any debris. Make sure the O-ring is fully seated and level in the groove and not pinched or twisted.
