Question
Which ISFET probes are compatible with portable compared to benchtop H-Series meters?
Summary
H-Series ISFET Electrode compatibility.
Answer
There are two types of ISFET pH electrodes for the H-series meters. There is an 8-pin Waterproof ISFET pH connector for portable meters, and a RJ-45 ISFET pH connector for the benchtop meters. The waterproof portable electrodes will have a W in the part number, where the RJ-45 benchtop will not.
An example the portable probe round tip (Catalog Number/Order Code PH W77-SS), with the benchtop version round tip (Catalog Number/Order Code PH77-SS).
The portable ISFET probes are not compatible with the benchtop H-series meters, and the benchtop ISFET probes are not compatible with the portable meters.
