1 Voltage electrode (inside, 2x)
2 Current electrode (ring, 2x)
3 Temperature sensor in graphite enclosure
4 Shaft
5 Connecting head with active sensor electronics
The sensor electronics with the stored sensor data is in the connecting head.
The data include, among other things, the sensor type and series number. With
each calibration, the calibration data is written in the sensor and the calibration
history is recorded. The data is recalled by the meter when the sensor is
connected and is used for measurement and for measured value documen-
tation. Storing the calibration data in the sensor ensures that the correct cell
constant is automatically used if the sensor is operated with several meters.
The digital transmission technique guarantees the failure-free communication
with the meter even with long connection cables. If the sensor firmware is
enhanced by VWR, it can be updated with the meter.
Recommended fields of application
On-site measurements in rivers, lakes and waste water
Fish farming
Groundwater measurements
Applications in the water lab
NOTE
Concentrated or highly oxidizing acids and organic solvents can damage
or destroy the sensor.
