The Telaire T8700 / T8700-D humidity and temperature transmitters utilize a rugged capacitive sensor that provides full-scale 0-100% RH measurement with unsurpassed response times, linearity and stability. Recovery to condensation and chemicals is excellent and an integrated filter helps ensure long life. All sensors undergo intensive digital calibration, certified against a primary NIST reference standard. NIST/NPL certificate available on complete transmitter at additional cost.

Telaire T8700 is designed to be highly configurable in the field or in your warehouse. By minimizing the necessary number of configurations, distributor inventory costs are reduced, and provide maximum flexibility to the installer. All versions feature field-selectable outputs (0 to 5V, 0 to 10V, 4 to 20mA) and a passive and 10K Type II thermistor. Signal-conditioned temperature is scaled from 32°F to 122°F (0°C to 50°C) and Relative Humidity is scaled over 0-100%.

All Telaire T8700 feature rugged flame retardant, UL-94V ABS plastic. Special care has been taken in the design of the wall mount enclosure to provide enhanced airflow, increasing sensor response time and virtually eliminating the potential of "self-heating" by transmitter electronics that can lead to decreased accuracy measurements.

All Telaire T8700 models feature a two piece enclosure with the back plate including terminal blocks eliminating the need to wire in a confined space and allow the unit to be pre-wired separate from the electronics. This is an especially attractive feature in unfinished construction, where exposed sensors and electronics could be damaged by moisture, drywall dust and paint.

With a two-year warranty on the transmitter, simplified inventory management, reduced installation times and field-serviceability, Telaire T8700 is a standard in reduced cost of ownership and performance-to-price ratio.
