Features In Detail

Details & Advantages

ACCURATE AND SENSITIVE

The RH70 Relative Humidity Sensor is accurate and sensitive to changes in the moisture content of the air. Response time is less than 1 minute, providing excellent measurement of the humidity at your site.

ROBUST

The sensor signal is a robust frequency (pulses) generated by the internal processor. The processor electronics are housed in an impact resistant IP66 Housing. The electronics themselves are solid state and not subject to drift. Replacing the Relative Humidity tip restores the sensor to factory calibration.

 

MEETS EPA REQUIREMENTS

The RH70 Relative Humidity Sensor meets EPA requirements in all states and territories of Australia (including AM-1, AM-2, AM-4 in NSW).

MEETS AUSTRALIAN STANDARDS

These sensors will allow you to meet the Australian Standards AS3580.14 when sited in accordance with the same standard. Environdata can provide your system with mounting infrastructure to mount the sensor at 2m above ground level in a suitable sensor screen. Alternatively, we can mount the sensor at 1.25m above ground level to satisfy the BoM installation guidelines.
