The OxyGuard pH and redox/ORP instruments and probes are also designed for no-nonsense measurement. Install it, calibrate it, then use it for long periods without having to re-calibrate or worry about moisture or electrical signal disturbance.

OxyGuard probes for pH and redox/ORP are essentially the same, and they all have impedance converters that effectively eliminate any electrical signal disturbance problems. There is special sealing so that moisture problems are also eliminated, and OxyGuard probes can operate under water indefinitely. They can be supplied with a cleaning device.

Two types of transmitters are available, pH Manta and Atlantic pH, and all have full galvanic isolation between input and output. OxyGuard also manufacture a unique pH measurement system for use on ultra-pure water. The very high impedance of such water presents some very special problems that the OxyGuard Pure Water pH Analyzer solves completely.

We also have  a hand- held pH or redox meter.

N.B. all OxyGuard brochures are in PDF format - you need Acrobat or the Acrobat reader to see them.
