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.

The Cond 550 (05802-08) controller has two sets of isolated and reversible 4 to 20 mA output for conductivity and temperature that allows it to be used as a proportional output. Also includes two sets programmable on/off relays.
