Chilled Mirror Sensor Model 1211HS - GE

Description

Model 1211HS is a general purpose, 2-stage chilled mirror sensor with 65ºC (117ºF) of depression capability. Model 1211HS can be used as in the laboratory as well as industrial applications. The sensor is available with an auxiliary liquid cooling jacket to extend the range resulting in an economical standard for the validation of compressed and process air to -60°C frost point. The 1211HS functions with any General Eastern M or E series monitors to provide a time proven hygrometer system that provides primary humidity measurement. The hygrometers system is calibrated to NIST traceable reference standards and is suitable for use as humidity transfer standard. General Eastern’s manufacturing and quality system is certified to ISO-9001 standards.

Model SIM-12H
The Model SIM-12H is a heated, 2-stage sensor with 65ºC (117ºF) of depression capability. It is designed for high dew point applications up to 85ºC (185ºF). For dew point measurements above ambient temperature, all components that come in contact with the sample gas must be heated to a temperature above the dew point, in order to prevent condensation and unreliable readings. For information on the Model HSS-12 heated sampling system, for use with the Model SIM-12H, refer to the Sampling Systems group on the Chilled Mirror Index page.

Features:

	Primary, fundamental measurement of dew/frost point.
	Hermetically-sealed, wire-wound 4-wire PRT
	NIST traceability
	Interchangeable with other General Eastern sensors without recalibration
	Continuous, on-line measurement
