| The 1000 series 1/4 Din conductivity and resistivity controllers have more features |
| The 1000 series 1/4 Din conductivity and resistivity controllers have more features than any other controllers in their price range! Their high +0.5% full-scale accuracy, 1 to 2000 second selectable time delay, and adjustable set point hysteresis bands mean you can trust these controllers for rapid on / off control of your critical processes.
Customize your controller to fit your exact application. Each unit is selectable for conductivity or resistivity control, isolated 0-20 or 4-20 mA recorder output; 70 or 220 VAC; normally activated or unactivated relays; normally open or closed relays; and manual or automatic temperature compensation. The compact 1¼4 DIN size fits into standard panel cutouts. The IP54 rated front panel keypad is weather resistant. |

Features |
- Removable terminal blocks
- Splash-resistant, IP64 rated membrane keypad
- Mounting hardware for easy panel installation
- Large dual display LCD for easy reading -features clear multiple annunciators, set points, and status and error messages
- Two set point, two SPDT relay operation -choose from lo/lo, lo/hi, hi/lo or hi/hi control
- Time delay adjustment on all relays -select from 1 to 2000 sec to minimize false alarms
- Battery backup of memory maintains setup when power fails
- Separate alarm relay -alerts you to set points exceeded for a specific length of time or a failed temperature sensor
- Separately adjustable high and low set point hysteresis bands -prevent rapid contact switching if your measured value is fluctuating near the set point
- Adjustable temperature coefficient -from 0.00 to 10.00% per °C lets you input your solution’s true temperature correction for higher accuracy
- Choice of 0.01, 0.1, 1.0 or 10.0 cell constants -for accurate readings in any solution
- 0-20/4-20 mA transmitter/recorder output — for remote monitoring and hard copy recording
- Protected against electromagnetic interference — units that meet CE requirements are available
- Push button keypad gives you fast access -to one-point calibration, switchable manual or automatic temperature compensation, and call up to view set points
- Two level password protection -first level allows quick access to calibration: second level lets you change set-up parameters
- LED indicators signal control activities -monitor controller status from a distance
