Description  more details

Features of the R36X series Electrochemistry controllers.

  • 2 electrochemistry channels for either pH, mV conductivity or Dissolved Oxygen
  • Ion channel (3620 only)
  • 2 Temperature Channels
  • Analog ouputs 4-20 ma
  • Relay outputs
  • Free Windows software (communications protocol on request)
  • On/Off or proportional Control
  • Units can be daisy-chained on the RS485
  • Password protection of settings
  • Stores up to 12000 values + temp, date and time (internal memory)
  • GLP reporting built in
  • Alarm can interrupt the controller in the event of a sensor probe failure


The R36x is sophisticated electrochemistry controller having two independent input channels for temperature and two inputs channels for electrochemisty probes. It can accept any combination of pH, mV, conductivity or dissolved oxygen probes. The two input channels are independent so that any two functions can be controlled simultaneously, each with its own temperature compensation, On/off control or proportional control.
There are four solid state relays programmable for high/low level control, wash programs or alarm functions.
A special alarm timer will interrupt the process control in case of an electrode failure.

The system includes a comprehensive set of calibration routines for each parameter including multi point calibration for pH and conductivity. The mV parameter can be calibrated for accurate ORP measurements.
The controller can accomadate a range of conductivity probes to match the application.
Use a 1 cm-1 electrode to control from 0.01 μS/cm to 200 mS/cm.
Use a 0.1 cm-1 electrode to control from 0.001 μS/cm to 20 mS/cm.
Use a 10 cm-1 electrode to control from 0.1 μS/cm to 2000 mS/cm.
The model 3624 includes a connection for 4 pole conductivity probe
Selectable reference temperature: 20° or 25°C.
Cell constant determination is automatic with any of three preprogrammed or user specified standards.
A special feature for accurate low conductivity measurements eliminates the capacitive component of the electrode and its cable (we recommend not to us use long cables when dealing with low conductivity measurement).
The Dissolved oxygen function operates with a galvanic oxygen electrode requiring no polarisation time and no zero calibration.
which and be calibrated in air. The DO function includes compensation for salinity 0-40 ppt and atmospheric pressure (600-1300hPa).

Both units includes an RS485 interface which can be used to daisy chain instruments together and to contect to a PC or login controller.

The option DIS software feature data aquistion, tabulation and file management compatible with Microsoft Windows. The system can used without the software using a straight data link such as hyperlink or with your own software (command set available on request)

The standard digital output is RS485 on internal screw terminals and various adaptors are available to make other digital interface - ethernet, RS232 and USB
