6309POT PH/ORP CONTROLLERS
Rugged and reliable pH/ORP analyzers/controllers.
FEATURES:
- Measures and controls pH, ORP and temperature
- Easy to setup and calibrate
- 5 programmable relays: 2 for pH, 2 for ORP and 1 for temperature
- Isolated and reversible 4 to 20 mA output for a single parameter
pH/ORP Controllers Product Description
The Global Water 6309POT multiparameter pH/ORP Controller measures, analyzes, and controls pH, ORP and temperature in one easy to use unit. The pH/ORP Controller’s setup and calibrations are done through a user-friendly menu that may be password protected. Calibrations can be performed quickly and accurately with automatic buffer recognition of U.S. or European buffer sets, with the values stored in the pH/ORP Controller’s nonvolatile memory. A large backlit display on the pH/ORP Controllers provide pH, ORP, and temperature plus the current mA output and relay status.
The WQ250 multiparameter pH/ORP controllers provide accurate on/off control via the five programmable relays or the 4 to 20 mA output may be used for proportional control. A standard RS-485 output allows for remote access via PC compatible computer and makes it possible to link multiple pH/ORP controllers to a common control system. The pH/ORP controllers built-in temperature and Automatic Temperature Compensation (ATC) functions may be used with an ATC type sensor or with a 10K ohm thermistor.
At power up, the WQ250 pH/ORP controllers perform a self-diagnostic to ensure proper operation. pH/ORP controllers electrode efficiency can be displayed to indicate when electrode maintenance is necessary. Housed in a watertight (IP65), ¼ DIN case, the 6309POT pH/ORP controllers include a terminal block that accommodates the tinned leads and spade lugs on industrial type pH and ORP electrodes.
NOTES: A BNC to Y adapter is required to maintain the IP65 rating when using sensors with a BNC connector. A signal amplifier is required for sensor cable runs over 40 feet.
