Chauvin Arnoux CA1246 Datalogging Thermohygrometer

The CA1246 is a 3-in-1 instrument for measuring relative humidity, ambient temperature, and the dew point. Equipped with a wide backlit display, the C.1246 offers all the useful functions for work in the field, such as Min, Max, and Hold, as well as spot or programmable recording possibilities. 

Communicating via USB or Bluetooth, it is possible to program alarms and record triggers on thresholds using the Data Logger Transfer software. 
As a thermo-hygrometer, the CA1246 is designed to simultaneously measure both the temperature and humidity of the air. It can measure relative humidity levels from 3.0 to 98.0% RH and temperature levels from -10.0 to +60°C.

The CA1246 is a data logging thermo-hygrometer; it can store up to 1 million records in its internal memory. The rate at which the instrument logs data is fully adjustable using the software - you can select a start/end date for the logging and also define how often the measurements will be taken (from 1 minute up to 2 hours). Thanks to a built-in magnet, you can easily leave the C.A1246  mounted to a surface, completely hands-free, during the logging procedure.
