Browse >100,000 products at ColeParmer.com Conductivity Control Cole-Parmer® Conductivity/ Resistivity Vs-DIN Controllers Don’t struggle to read measurements—backlit LCD for clear display - Get more measurement accuracy with automatic temperature compensation - Select either programmable on/off relays or isolated and reversible 4-to-20 mA output - Easy installation with universal power input from 100 to 240 VAC COND 300 controller has two sets of programmable on/off relays for high/low control to activate an alarm, a pump, or another device. COND 350 controller has an isolated and reversible 4-to-20 mA output for conductivity or resistivity that allows it to be used as a proportional output. Cole-Parmer® Conductivity/ TDS V4-DIN Controllers Ready to go when you are - Easy, one point calibration saved in memory to measure upon start-up - Extended options include isolated and reversible 4-to-20 mA output and RS-485 output for remote access - Ensure security of system with password protection Large graphic LCD with backlight simultaneously displays conductivity or TDS, temperature, cell constant, temperature coefficient, relay status, and transmitter current output. User-selectable cell constants, reference temperature and temperature coefficients, and automatic temperature compensation ensure measurement accuracy. COND 500 controller has one isolated and reversible 4-to-20 mA output and three sets of programmable on/off relays: two for conductivity and one for temperature—ideal for high/low control to activate an alarm, a pump, or another device. COND 550 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. Compatible with a 10 KQ thermistor conductivity cell.
