pH, ORP and Conductivity Controllers

RAHA supplies all types of Controllers such as:

* Microprocessor Controllers
* Panel Mounted Controllers
* Wall Mounted Controllers
* Mini Controllers
* Wide range of Equipment also available for different applications

Microprocessor Controllers

These hi-tech micro processor pH and ORP controllers offer a multitude of possibilities, from single or dual set points, to ON/OFF or proportional dosage, from galvanically isolated recorder outputs or bi-directional RS232, to high and low alarms, and much more.

For maximum safety of installations, the exclusive fall-safe protection warns the user as soon as a power interruption occurs or connection wires are tripped.  The controllers are equipped with a differential input to prevent grounding troubles, thus ensuring longer life to the sensors.

Panel Mounted Controllers

These inexpensive pH, ORP and Conductivity meters have been designed for ease of operation: front keys and trimmers allow easy calibration and settings, and LED's show the user the actual operation mode at any moment. Extractable terminal modules make wiring simple and fast. Housed in a DIN 43 700 casing, all meters feature galvanically isolated recorder output, Liquid Crystal Display (LCD), Socket for Pt 100 temperature probe and alarm relay.

Two versions are available: direct electrode or 2-wire 4-20 mA transmitter input. An exclusive consent feature coordinates dosage from pH and ORP controllers in order to prevent overdosing of chemicals.

Auto-diagnostic functions allow to prevent malfunction and failure in the process system: by simple pressing a key the user can quickly compare current readings with theoretical values to verify the status of meter and effectiveness of sensors at any moment.

  • Large user-friendly LCD display
  • Special Casing
  • Recorder Output
  • Alarm
  • Two types available
  • Self-Diagnostic feature
  • Compare readings
  • Simple and convenient
  • Easy to use
  • One year Warranty

Wall Mounted Controllers

The WM Series is provided with mounting holes molded into the housing to assure simple, quick and secure wall installations. Panels are no longer needed for this instrumentation, so that it can be mounted close to the process equipment. In addition, all meters have standard sockets for direct probes, pumps or electro- valves connections. These controllers are available also in dual range versions: pH and ORP or pH and conductivity can be controlled at same time with one unit.

These Controllers are housed in rugged IP %% rated casing preventing ingress of liquids. Material resist most of chemicals, protecting the unit from hazardous spills and splashes. Settings and calibration procedures can be performed through easily accessible trimmers and knobs and the front panel. Furthermore, a LCD continuously show readings and helps the user during operation.

Wall Mounted Controller
Features:
  • Mountable on Wall
  • No panels needed
  • Different types available
  • LCD display
  • Special Casing
  • Simple and convenient
  • Easy to use
  • One year Warranty

Mini Controllers

Mini Controllers are the smallest panel mounted process instrumentation on the market. This feature allows easy installation with a low investment whatever space is a problem, such as direct machine mounting. This range includes pH, ORP, Conductivity and level controllers. LED's on the front panels indicate the correct operational mode. In addition, easy accessible keys, knobs and trimmers allow quick calibration and settings; on the rear, extractable terminal modules have been designed for simple wiring.

The pH and ORP controllers come with a built-in 3 1/2 digit LCD and accept direct input from any combination electrode with a BNC connector. Isolated recorder output is also featured by these pH and ORP controllers.

Mini Controller

Different compact conductivity controllers are available depending on the range and relay activation: high and low set point. These mini conductivity controllers are supplied complete with 12 VDC voltage adapter and conductivity probe.

Level controllers are 2-wire transmitters for long distance control of low and over level in a tank. LED's on the front panel continuously show the level of liquid in the reservoir. Two relays are provided to connect external electrical devices such as an alarm for overflow condition or a pump for low level status. Stainless steel level detecting bars provide excellent durability against most liquids. For maximum versatility, they come with threads at either and for extension at user customizing lengths.

Mini Controller
Features:
  • Small in Size
  • LCD display
  • Alarms
  • Recorder output
  • Simple and convenient
  • Easy to use
  • One year Warranty
