Cole-Parmer 05802-22 500 PH 500 pH/ORP/Temperature 1/4 DIN Controller

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 user selectable, 10K NTC, 3K Ohm Balco, or 1000 Ohm RTD.

Features:

• Graphic LCD for clear measurement display
• Automatic buffer recognition of US and NIST buffers
