DewPro MMR2250

DewPro MMR 2350 Relative Humidity Analyzer

An economical process control instrument in a rugged industrial package, the rh-plus MR2350 mid-range dew point and relative humidity analyzer facilitates control of many manufacturing processes. The MR2350 combines with the MDR3 probe, and is available both in wall mount and panel mount models.

The microprocessor-controlled analyzer features user-programmable functions including dew point and relative humidity measurement, calibration data, alarm set points, and a variable output range. The MR2350 features an available second output for temperature, which further increases its versatility

Features:

	Line powered
	Wall-mount and panel-mount versions – NEMA 4X(IP67)
	Easily Field Calibrated
	Up to two outputs and two alarms

Options:

	Wall-mount version
	Second output for temperature
