ORP (oxidation reduction potential, also known as redox) measurement is used to
indicate the presence of oxidizing or reducing conditions in water. This technology
has gained recognition worldwide and is found to be a reliable indicator of bacteriological
Some applications for ORP or redox measurement include chlorine testing, bleaching
operations, estimation of bacteria kill times, or reduction of chromate wastes.
For example: with a value of 600mV, the life of E.Coli in water is about 2 minutes;
with a value of 700, the bacteria is killed in seconds.
This handheld ORP meter is designed for the field, combining accurate electronics
and a rugged, field-ready design. Features include:
- ORP measurement from -999 to 999mV with a resolution of 1mV, +/-4mV accuracy.
- Automatic electronic self-calibration and data validation
- Simulated analog bargraph display of ORP reading change
- Waterproof floating case
