PROBES
CONDUCTIVITY PROBES
Hanna Instruments was the first instrumentation manufacturer to offer a 4-ring potentiometric probe with a conductivity meter. The potentiometric method of measuring electrical conductivity in liquids is by far the most accurate method available today. The four rings are aligned concentrically on the probe shaft. The two outer rings apply a voltage which creates a buffer field around the two inner rings. The inner rings pick up a current and measure the conductivity of the liquid inside the buffer field. This completely eliminates the polarization which occurs in the 2-ring amperometric method.
Without polarization, the probe can also measure a larger range of conductivity because it does not suffer from electrolysis. This 4-ring method is used in all of the following probes.

HI 766 K-TYPE THERMOCOUPLE PROBES
These Probes are all specially constructed for excellent contact with the surface being measured. The several different options below are designed to meet all of your surface temperature measurement needs. Due to the high surface temperatures involved, it is important that the probe handle does not reach a temperature above 302°F (150°C). If this happens, the probe may be damaged. Response times all refer to 63.2% of measuring range.
