The Sensor Scientific Duct Sensor with Handy Box enables an accurate tempera-
ture measurement in multiple applications such as mechanical rooms, ducts, pipes
and immersion installations. The assembly consists of a 304 stainless steel tube
housing and handy box. Operating temperature range is from - 10°C to +110°C
(+10°F to +230°F) Duct Sensor is also available in an RTD (Resistance
Temperature Detector) form with resistance values of 100, 500, 1,000 & 2,000 Ohms
at 0°C.
Standard Configuration:
Sensor in stainless steel tube and
wall mountable handy box.
Optional Configuration:
Sensor in stainless steel tube, handy box
and mounting bracket.
Wiring:
All electrical connections and wiring must comply with the National Electrical
Code and with local electrical codes.
Ordering Information
