Product Overview

Telaire T8700 Wall Mount Humidity and Temperature Transmitters are precision instruments designed for HVAC control applications. They offer robust performance with a capacitive sensor providing full-scale 0-100% RH measurement, excellent response times, linearity, and stability. These transmitters feature field-selectable analog outputs (0-5V, 0-10V, 4-20mA) and active/passive temperature sensor outputs. The modern enclosure is made of rugged, flame retardant UL-94V ABS plastic, designed for enhanced airflow and accuracy. Installation is simplified with a two-piece enclosure and pre-wired terminal blocks. The T8700 series also boasts enhanced field serviceability with a replaceable RH sensor tip module, minimizing downtime and costly recalibrations. These transmitters are ideal for applications requiring accurate and reliable humidity and temperature monitoring.
