ORP-1000A Oxidation Reduction Potential Sensor
The Greenspan ORP-1000A is a fully submersible oxidation-reduction potential (ORP) sensor designed and manufactured in Australia, providing a calibrated 4-20 mA output on low-voltage power; an internal-logger version is available as the ORP-1000L.
- Range
- ±500 mV, ±1000 mV, 0-1000 mV (factory calibrated)
- Output
- Analogue 4-20 mA
- Supply
- 11-13.2 V DC
Overview
In detail
How it works
A platinum electrode with an internal reference measures oxidation-reduction potential and outputs a calibrated 4-20 mA analogue signal; the electrode is field replaceable, and a replaceable reference protection ring guards against fouling.
Features
Optically isolated signal conditioning, a robust easy-clean design and low power requirements suit a wide operating temperature range. An internal logger can be fitted to convert the unit into the logging ORP-1000L model.
