DESCRIPTION The new Senva HT1 Series comes in our newly engineered enclosure making it the most attractive and quickest-installation humidity sensor on the market. Designed with a universal analog output and a variety of thermistor options allows flexibility on-site. It mounts easily in any junction box or it can be unobtrusively mounted directly to drywall using Senva’s built-in drywall clamps. Also available in a surface-mount enclosure. Save installation time and energy costs with this versatile product. Attractive and low-profile design ▪ Enclosure mounts easily in junction boxes ▪Innovative drywall clamps allow unobtrusive and secure mounting without a junction box ▪ Ideal for schools, offices, etc Field calibration with LCD or LED ▪ Field calibration scaled adjustment allows for the calibrated RH value to be changed as needed to maintain certification. ▪ Dip-switch selectable 0-5V/0-10V/4-20mA universal output Options for any job ▪ Thermistor or transmitter outputs for temperature (optional) Superior RH sensing ▪ 2%, 3%, and 2% NIST calibrated RH accuracy options ▪ Field-replaceable humidity element ▪ On-board temperature compensation eliminates temperature coefficient errors and achieves high repeatability and offset stability NEW !Higher Reliability, Faster Installation, Superior Accuracy | Sense the difference | 77 AIR QUALITY HUMIDITY/TEMPERATURE HT1R Series DIMENSIONS SPECIFICATIONS Power Supply12-30VDC/24VAC (1) , 100mA max.
