Honeywell On-Surface Temp Sensors 6655 Series
The Honeywell On-Surface Temperature Sensors, 6655 Series, are lower cost thermistor-based sensors that use a compact, low-profile thermostat package. The 6655 series measures temperature accurately
on most flat surfaces and pipes in non-condensing applications. With a
robust design and ease of installation, no calibration is needed and a
wide temperature range of -20ºC to 100ºC allows application flexibility.
