LIQ-PDS-397
A high performance sensor with ease of maintenance in mind
Rosemount 397 pH/ORP sensors feature a TUpH reference design and are designed to be used with the Quik-Loc kit allowing for easy
installation and maintenance. These low maintenance sensors are ideal for measuring pH or ORP in aqueous solutions with high levels
of suspended solids.

Rosemount 397 TUpH pH/ORP Sensor
Overview
June 2017
A TUpH Sensor Design
Excellent coating resistance and extended sensor life in
process solutions with high levels of suspended solids.
Highly chemical resistance with polypropylene and Tefzel
sensor body options.
Operates in process temperatures up to 100 °C and in
pressures up to 100 psig.
Helical reference pathway slows down the effects from
poisoning ions.
Ease of Maintenance and Installation
Quik-loc kit allows for quick and easy access to Rosemount
397 sensor without cable twisting.
Visual confirmation that the sensor is locked into position.

Quik-Loc Features and Applications
The Quik-Loc Kit consists of an adapter and a coupler. The PEEK adapter enables the Rosemount 397 pH sensor to fit into a 1 in. MNPT
coupler for quick disconnection without sensor cable twisting. The 316 stainless steel Dixon coupler is sealed with an EP gasket and
features locking arms. The B100 mechanism keeps the coupler arms locked in place until removal of the sensor is desired. The
Quik-Loc Kit is not recommended for use in processes with hazardous, cor- rosive, or strong oxidizing chemicals due to a risk of spray
or bodily injury.
