For pH sensors only:
• Temperature measurement
• Impedance measurement (blue wire from the controller):
• Program the control frequency upper and lower limits (refer to the 9500 user manual):
• Glass impedance: 50 Mohm to 500 Mohm
• Reference impedance: 1 to 100 kohm
8362 sensor
The sensor is provided with two cables of 3 meters as standard, one for the pH sensor and one for
the temperature sensor. As an option, cables of 10 or 20 meters can be supplied. Attach the device
to a suitable static object using the U-bolt (No. 3 in
