Eutech CON 1000 1/4 DIN Conductivity Controller and Eutech RES 1000 1/4 DIN Resistivity Controllers

Eutech, CON 1000, Conductivity Controller, Eutech RES 1000, Resistivity Controllers, Oakton InstrumentsFast on/off control with high +/-0.5% accuracy- a performance breakthrough!

  • Large dual LCD shows measurement plus temperature simultaneously

  • Two set point, two SPDT relay operation... choose from lo/lo, lo/hi,or hi/hi control

  • Separate alarm relay

  • View control set points and other set up information with a button press

  • Adjustable temperature coefficient from 0.00 to 10.00% per ºC

  • Choice of 0.01, 0.1, 1.0 or 10.0 cell constants

  • Push button one-point calibration

  • Two level password protection prevents tampering with settings

  • LED indicators signal control activities to monitor controller status

  • Built-in memory backup maintains set up if power fails

Eutech Instruments 1000 series 1/4 DIN conductivity and resistivity controllers have an advanced set-up mode to easily customize features. Their 0 to 2000 second selectable time delay and adjustable set point hysteresis bands mean you can tailor control relay action to meet your needs.

Each unit is selectable for isolated 0-20 or 4-20 mA transmitter/recorder output; 110 or 220 VAC; normally open or closed relays; and manual or automatic temperature compensation. The compact 1/4 DIN size fits into standard panel cutouts. The IP54 rated front panel keypad is weather resistant. Includes mounting hardware.
