MORE ABOUT THIS ITEM Cole-Parmer online controllers offer features found in more expensive models. Backlight, graphic LCD simultaneously displays measurement, temperature, cell constant, temperature coefficient, relay status, and transmitter current output. Calibration data is stored in memory; making the unit ready for measurement. User selectable cell constants, reference temperature and temperature coefficients; and automatic temperature compensation ensure measurement accuracy. Password protection, RS-485 for remote access, and the isolated and reversible 4 to 20 mA output offer extended data options with security. Compatable with a 10K thermistor conductivity cells. Cond 500 (05802-06) controller has one isolated and reversible 4 to 20 mA output and three sets of programmable on/off relays: two for conductivity and one for temperature--ideal for high/low control to activate an alarm, a pump, or another device.
