Davis Vantage Pro2 ISS Temperature & Humidity Sensor 7346.070 / 7345.221

The latest and most accurate Davis digital temperature and humidity sensor only for the Vantage Pro2 sensor suites and temperature and humidity stations.

Available in two options, 7346.070 with standard length cable for sensor suites, or 7345.221 with a 7.6m (25ft) cable. 

This latest revision includes an enhanced double coated PCB seal and the white sensor cap with screen. Importantly the SHT31 sensor is the enhanced temperature and humidity sensor that gives greater accuracy than the earlier Davis products using the SHT11 and SHT15 sensors in the 7346.166 models.

This sensor offers exceptional accuracy of within +/- 2% from 0-100% humidity and within +/- 0.2C from -5C to +65C on temperature.

 

Installation Notes

When using this sensor with ISS transmitters manufactured between 2006 and December 2015 a small offset adjustment is required to the temperature readings obtained on the console.

Using a pre December 2015 transmitter (manufacturing code AR and earlier) with this temperature / humidity sensor will result in the Temperature reading 0.5C (0.9F) high. To counteract this error a calibration offset should be applied on the console to reduce the temperature by 0.5C (see your console manual for calibration details).

To assist with the replacement of the temperature and humidity sensor Davis have kindly provided the above videos.
