Chauvin Arnoux CA1246 Thermohygrometer

The Chauvin Arnoux CA1246 Thermohygrometer measures air temperature from -10˚C to 60˚C with a resolution of 0.1˚C and an accuracy of ±0.5˚C whilst the humidity range goes from 3 to 98% with 0.1% resolution and ±2% accuracy. It is also capable of calculating dew point and displaying this on screen.

A wide backlit display shows readings for both humidity and temperature simultaneously in addition to dew point. The user can set various alarms and the Chauvin Arnoux CA1246 has minimum and maximum recording as well as data hold.

The Chauvin Arnoux CA1246’s internal memory saves up to 1 million measurements and the user can save spot measurements or set a recording programme. The thermohygrometer has a magnetic attachment and can run off the mains so it is suitable for longer-term measurement.

It has both USB and Bluetooth wireless connectivity for performing data transfers and a Chauvin Arnoux Data Logger Transfer software package is available as a free download from the Chauvin Arnoux website. This software will enable data transfers and automatic report generation.

The Chauvin Arnoux CA1246 is very compact and unobtrusive and it has a maximum battery life of three years. The IP54 casing is resistant to water and dust ingress and Chauvin Arnoux provide a two-year manufacturer’s warranty.
