XI) Temperature compensation

a) The instrument is calibrated to a temperature coefficient of 2% per degree C over

the measurement temperature range of 5 to 55°C. Temperature compensation
refers all measure values to 25°C.

XII) Temperature compensation thermistor

a) External resistive can be used to perform temp. compensation, when conductivity

probes other than the Cat. No. 105 probe is used. Refer to following table. The
replacement conductivity probe must be made of platinum element and a nominal
