	Economical controller designed with the features and reliability of a much more expensive instrument
	Reliable power supply withstands voltage fluctuation from 85 to 265 VAC
	Adjustable hysteresis prevents rapid relay switching near set points
	Adjustable TDS factor, temperature coefficient, and selectable cell constants
	Galvanically isolated 4-20 mA output for remote monitoring or hard copy recording
	Removable terminal strips offer quick and easy connections
	Battery back-up of memory maintains set-up if power fails

These sturdy, compact controllers withstand voltage fluctuations from 85 to 250V AC/DC! They are ideal for installation were electrical fluctuations are common, or install them in series throughout areas of differing electrical conditions.

Advanced setup mode lets you select cell constant, TDS factor, temperature coefficient, manual or automatic temperature compensation, hysteresis band and more. It also lets you view previous calibration points.

The 1/8 DIN housing is ready to install in standard panels and NEMA rated boxes. Includes mounting hardware; accepts probes with stripped ends and Pt 100 RTD ATC elements.
