550 pH/Temperature 1/4-DIN Controller

Isolated and reversible 4 to 20 mA output allow for proportional output, SPDT relays for On/Off control|Backlight, 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. Backlight, 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.
