Unsurpassed Sensor Performance
Telaire T8700 utilizes 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
certificate is available at additional cost (part no.
3PTCERT).
Rugged, Attractive Enclosures
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.
Simple, Fast Installation
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.
Maximum Flexibility
Telaire T8700 is designed to be highly configurable
in the field or in your warehouse. By minimizing the
necessary number of configurations, Telaire reduces
distributor inventory costs and provides 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%.
Lowest Cost of Ownership
With a two-year warranty*, simplified inventory
management, reduced installation times and field-
serviceability, Telaire T8700 is a standard in reduced
cost of ownership and performance-to-price ratio.
*Transmitter only, one year warranty on replaceable sensor.
*NIST/NPL certificate available on complete transmitter at
extra cost.

Wiring Features
Telaire T8700 is fast and simple to install; the wiring diagram label shown is fixed to the inside of the back plate,
making it easy to read and reducing the risk of miswiring. After wiring is complete, the front part of the enclosure,
including the electronics, can be simply snapped on and held with a single safety screw.

Enhanced Field Serviceability
The T8700 series features a field-replaceable Relative
Humidity (RH) sensor tip module that allows the end
user to replace the sensor on-site while maintaining
±2.5% RH accuracy. The user simply powers off the
unit, installs the new sensor module and powers
back the unit. This virtually eliminates the need for
time consuming and costly factory calibration, while
reducing downtime during service intervals to near
zero.
