Consort R363 Features

• Control:
• Two independent channels allow to control any two functions simultaneously, each with its own temperature compensation.
• On/off or proportional control.
• Four solid state relays programmable for high/low level control, wash program or alarm functions.
• Allows to stop temporarily the control (relays off) without holding the measurements.
• Wash program for an automatic periodical cleaning of the electrodes. Special alarm timer to interrupt the process control in case of an electrode failure.
• pH:
• Multi-point (1...5) calibration for more linearity.
• Selectable resolution from 0.001 pH to 0.1 pH.
• Automatic calibration with any of nine pre-programmed pH buffers.
• mV:
• Features mV calibration for accurate ORP measurements.
• Selectable resolution from 0.1 mV to 1 mV.
• Conductivity:
• Multi-point (1...3) calibration for more linearity.
• 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.
• Selectable reference temperature: 20° or 25°C.
• Automatically selects correct range and frequency.
• Automatic cell constant determination with any of three preprogrammed standards.
• Accurate low conductivity measurements by eliminating the capacitive component of the electrode and its cable (avoid the use of long cables!).

• Dissolved oxygen:
• Operates with a galvanic oxygen electrode requiring no polarisation time and no zero calibration.
• Selectable resolution from 0.01 mg/l (0.1%) to 0.1 mg/l (1%).
• Rapid air calibration.
• Manual salinity compensation 0-40 ppt.
• Automatic air pressure compensation 600-1300 hPa.
• Temperature:
• Reads temperatures with 0.1°C resolution.
• Manual or automatic temperature compensation.
• Calibrates temperature probe for quality measurements.
• Free chlorine:
• Operates with a double platinum electrode in tubings of a water system.
• Selectable resolution from 0.01 mg/l to 0.1 mg/l.
• The rate of flow should be at least 20 cm/s and kept constant by using a special bypass vessel.
• Calibration is performed by adjusting the controller to a value measured with a photometer.

• Inputs
• Two BNC inputs for pH, mV, conductivity or dissolved oxygen, one BNC input for free chlorine and one BNC input for temperature.
• Outputs
• Two programmable 4-20 mA analogue outputs, for connection to a proportional pump, a PLC or an industrial recorder.
• RS485 interface for connection to a computer.
• Connections
• All connections, except for the inputs, can be done through the internal screw terminals.
• Cabinet
• Robust dust and splash-proof cabinet for wall mounting.
• Display
• Bright LCD screen with white backlight for better readability.
• Permits to switch between a single measurement display plus temperature (large characters) or a simultaneously display of all measurements plus temperature (small characters).
• The interactive LCD screen provides step by step instructions in the language of your choice (English, Dutch, French, German).
• Real-time clock displays time and date.
• Shows a GLP report on the LCD screen.
• Data-logging
• Stores up to 12000 values including temperature, time and date at a programmable interval.
• An optional powerful data acquisition software for PC and RS232/RS485 adaptor is available separately.
• Can be connected in a network system with up to 31 controllers and a computer.
• Two-way communication with any computer using RS485.
• Programmable identification number.
• Stores minimum/maximum readings for each channel.
• Special features
• Three year warranty.
• No electrical interference between electrodes in the same solution.
• Galvanic input/output insulation eliminates ground loop interferences.
• A first special timer can start a wash program for an automatic periodical cleaning of the electrodes.
• A second special timer can give alarm to interrupt the process control in case of a pump overfeed or an electrode failure.
• Password protection prevents any unauthorised access to the instrument.
• Easy in-line calibration without removing the electrodes from their fittings.
