GLI3/4 Комбинированный ORP/pH-зонд

Instrument Features

• Compatible with most pH and ORP sensors

• Automatic temperature compensation

• Combination pH/ORP sensors available with rugged bulb electrodes, easy-to-clean flat-surface electrodes, and HF (hydrofluoric acid) resistant electrodes

• An ORP/pH measuring instrument designed specifically for special applications

• The dual salt bridge design with reference electrode extends sensor service life; additionally, the electrode has a built-in ground contact

• The combination pH/ORP sensor body is made of chemically resistant Ryton or PVDF material

• Multiple materials and mounting options available to handle various special process conditions; a stable and reliable ORP/pH measuring instrument

General Purpose Sensor

The general purpose pH/ORP sensor body is made of RytonR material and features 3/4-inch NPT threads on both ends. The sensor can be directly installed in a standard 3/4-inch tee for flow-through installation or mounted at the end of a pipe for immersion installation. Flow/immersion mounting assemblies are available in a variety of materials to suit different applications.

Insertion Sensor

The insertion pH/ORP sensor has a longer, threadless PVDF body with two VitonR O-rings that provide sealing when used with HACH insertion mounting assemblies. The electrode can be inserted into and withdrawn from pipes or vessels without interrupting the process flow.

Sanitary Sensor

The sanitary pH sensor features a PVDF body with a 316 stainless steel liner and a 2-inch flange. The sensor mates with a standard 2-inch tri-clamp fitting. Optional HACH sanitary mounting assemblies include a standard 2-inch sanitary tee, sanitary clamp, and VitonR sanitary gasket.
