ORP Electrode for Process Control and Monitoring - HI2001

SKU: HI2001


HI2001 is an economical process ORP probe with a BNC connector. The BNC connector is universal and works with any ORP (mV) meter that has a BNC probe input. The HI2001 is a double junction design with a polymer reference for long life in many common industrial applications.

1/2" and 3/4" NPT threads for in-line and submersion mounting

Chemically resistant PTFE junction

Universal BNC connector

The HI2001 has a  platinum sensor  for the measurement of ORP for a variety of applaictions including plating, swimming pools, water treatemnt and food disinfection. The platinum sensoris commonly used to monitor the addition of oxidizing chemicals including chlorine, chlorine dioxide and ozone.  The probe can be used for monitoring the additin of reducing chemicals like sodium metabisulfite.

This cost effective probe has threads on both ends for in-line or submeraion mounting.

Sensor Type

Platinum sensor provides the best response over a wide range of applications.


Polyvinylidene fluoride (PVDF) is a plastic that is resistant to most chemicals and solvents. It has high abrasion resistance, mechanical strength, and resistance to ultraviolet and nuclear radiation. 

PTFE Junction

This type of junction is often used on electrodes with polymer electrolytes. Porous polytetrafluoroethylene (PTFE) is a hydrophobic material that is available with different porosities that helps to minimize clogging. PTFE is widely used in industrial applications due to its high range of chemical resistantance.

BNC Connector

The HI2001 uses a BNC connector. This type of connector is universal in that it can be used on any ORP process controller, indicator, or transmitter that has the female BNC probe input.

External Thread

The ½” NPT thread of the HI2001 front end allows for in-line installation in pipes while the 3/4" threads on the backend (cable side) allows for submersion mounting with tanks or other vessels.
