1. Specications
The Model PH8HS Submersion Type Holder is designed for use in open tanks, reactors, or
wastewater drains, and allows the whole sensor to be submerged with only the sensor tip exposed to
the solution. Holders with ultrasonic or brush cleaning options are available. The Model PH8HSF is a
version with ultrasonic cleaning for high-pressure explosionproof applications.
