Eutech Instruments 1/2-DIN DO 2000 Oksijen Kontrol Cihazı

Eutech Instruments 1/2-DIN DO 2000 Oksijen Kontrol Cihazı

Advanced features at an economical price!
Programmable for on/off, proportional (P), or proportional integral (PI) control
Adjustable back-lit and UV-protected LCD shows both DO reading and temperature

Four programmable relays with time delay capabilities�two set point relays, one wash relay, and one alarm relay


The DO 2000 combines advanced features and simple set up to provide superior dissolved oxygen control in water treatment and monitoring, galvanic-decontamination, chemical processing, food processing, and neutralization process applications. IP65-rated housing features a large LCD with clear enunciators, alarm status, and operational and error messages. LED indicators allow you to visually monitor transmitter status. Easily access menu-driven programming, calibration, and sensor offsets from the push-button keypad.
P or PI control modes offer pulse length or pulse frequency control. Relays feature a 0 to 2000-second time delay adjustment. Additional features minimize environmental or operational errors and false responses. The housing provides protection against electromagnetic interference. Non-volatile memory keeps set data from being erased due to power failure. Two-level passwords prevent tampering with calibration and set up modes. Built-in calibration checks and compensation for temperature, salinity, and barometric pressure ensure good data. Separately adjustable high and low set-point hysteresis prevent chattering of relays around the set points.
