Technical Information
Temperature Sensor
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; 4 minutes typical to 90% in stirred water, unmounted
Logger
Logger Operating Range	-20° to 70°C (-4° to 158°F)
Buoyancy (Fresh Water)	MX2203: 3.1 g (0.11 oz) negative MX2204: 7.6 g (0.27 oz) negative
Waterproof	MX2203: To 122 m (400 ft) MX2204: To 1,524 m (5,000 ft)
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).

Transmission Range	Approximately 30.5 m (100 ft) line-of-sight
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 the app. Faster logging intervals and statistics sampling intervals, burst logging, remaining connected with the app, excessive downloads, and paging may affect battery life. See Battery Information for detailed instructions on replacing the battery in the MX2203 logger.
Memory	96,000 measurements
Full Memory Download Time	Approximately 45 seconds; may take longer the farther the device is from the logger.

Can I download data from MX2200 Series loggers deployed in water?

No, the MX2200 Series need to be taken out of the water to download the data.

Do I need an optical shuttle to download data from the MX2200?

No, you need to have a mobile device such as a phone or tablet that runs iOS or Android operating systems and that have Bluetooth Low Energy (Bluetooth 4.0 or above) in order to download the data.

Is an event recorded in the data file when the logger is submersed or removed from the water?

With the MX2203 & MX2204, the user has the option while configuring the loggers to use the Bluetooth Off Water Detect. The logger will not advertise when the presence of water is detected. Once the logger is removed from the water, advertising will automatically turn on, thereby not requiring you to push a button (or use a magnet) to wake up the logger when you need to connect to it. This option preserves some battery power. Note: The logger will check for the presence of water every 15 seconds when this is option is selected.

Do the new MX2200 Series water loggers replace the existing Pendant and TidbiT water loggers?

No, we will continue to support the TidbiT, Pendant, and Water Temp Pro optical products although we encourage folks to take a look at the new features of the MX2200 Series.

Can I use HOBOware software to graph, analyze and export the data?

You have the ability to share a .HOBO file via email, or use HOBOlink.com to then open up the file in HOBOware to do additional data analysis like combining graphs and analyzing your data further. Note that HOBOmobile can also directly output a .XLSX & .CSV file format if you choose to work in Excel
