MORE ABOUT THIS ITEM

Cole-Parmer online controllers offer features found in more expensive models. Graphic LCD simultaneously displays measurement, temperature, electrode status, relay status, and transmitter current output. Calibration data is stored in memory; making the unit ready for measurement. Password protection, RS-485 for remote access, and the isolated and reversible 4 to 20 mA output offer extended data options with security.

The pH 550 ( 05802-18) 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 four programmable on/off relays: three for pH and one for temperature. ATC element is a 10K NTC.
