  • Isolated and reversible 4 to 20 mA output allow for proportional output, SPDT relays for On/Off control
  • Graphic LCD for clear measurement display
  • Automatic buffer recognition of US and NIST buffers
  • Automatic temperature compensation
  • Password protected ensures security of system
  • RS-485 output for remote access allows multiple unit control from your computer

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/ORP 500 (05802-22) controller has one isolated and reversible 4 to 20 mA output and five programmable on/off relays: four for pH and one for temperature–ideal for high/low control to activate an alarm, a pump, or another device. ATC element is a 10K NTC or 3K Ohm Balco or 1000 Ohm PT RTD user selectable.
