Overview
Rugged Sensor Design
Mechanical and thermal shock resistant special pH sensitive
glass membrane for extended sensor life in high temperature
sterilizations.
Non-flowing junction minimizes maintenance requirements
and eliminates the need for expensive pressurization
hardware.
Extend sensor life with poisoning ion resistant double
junction reference cell.
Ceramic body and high temperature cable permits autoclave
sterilization up to 130°C.
Versatile Installation Options
Designed to fit industry standard insertion hardware.
12 mm electrode diameter allows direct replacement of most
manufacturers'steam sterilizable pH sensors.

Performance
In typical applications,the sensor will perform continuously for 50 steam sterilization cycles.
pH Range
1.67-4.01 pH 96%linearity
4.01-12.0 99%linearity
12.0-13.0 pH 97%linearity
Repeatability
±0.05 pH
Automatic Temperature Compensation
Temperature compensation is generally not required since most applications operate very near pH 7(isopotential point).
When temperature compensation is required a separate RTD can be used with compatible instruments.
