1. Overview:
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.
- A programmable alarm function prevents the overdosing of chemicals in the process liquid. Each time a pre-set level is exceeded the corresponding elay is closed and the alarm timer starts to count down. When this level is still exceeded after count down of the timer all relays will be opened and an alarm be given. The system should then be checked thoroughly for e.g. broken electrodes, interrupted cables, empty vessels, etc...
pH:
- Multi-point (1...5) calibration for more linearity.
- Selectable resolution from 0.001 pH to 0.1 pH.
- Automatic calibration with any of eleven pre-programmed and five user specified pH buffers.Create your own buffer/temperature tables!
mV:
- Features mV calibration for accurate ORP measurements.
- Selectable resolution from 0.1 mV to 1 mV.
Ion (R362x only):
- Direct concentration measurement.
- Multi-point (2...5) calibration and an additional blank correction for measuring low concentrations.
Conductivity:
- Multi-point (1...3) calibration for more linearity.
- The 4-pole design reduces considerably the problems of polarisation and fouling. By utilising four electrodes, no current flows through the measuring circuit. The AC-current is only applied to the outer pair of rings allow-ing the inner pair of electrodes to measure the voltage without any polarisation effects. A 4-pole electrode permits to measure with the highest degree of accuracy and linearity (R3624 only).
- An electrode with a typical cell constant of 1 cm-1permits to measure from 0.01 µS/cm to 200 mS/cm in five ranges.
- An electrode with a typical cell constant of 0.1 cm-1permits to measure from 0.001 µS/cm to 20 mS/cm in five ranges.
- An electrode with a typical cell constant of 10 cm-1permits to measure from 0.1 µS/cm to 2000 mS/cm in five ranges.
- Automatically selects correct range and frequency.
- Selectable reference temperature: 20° or 25°C.
- Automatic calibration with any of three preprogrammed and three user specified standard solutions.Create your own standard/temp. tables!
- 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 polarisa-tion 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.
- Automatic air pressure compensation 600-1300 hPa.
Temperature:
- Reads temperatures with 0.1°C resolution.
