OxyGuard was founded to meet the need for comprehensive yet easy to use stationary, multichannel dissolved oxygen monitoring and alarm systems for use in aquaculture. This need was met with devices that set new standards for metering and monitoring equipment, devices that we at OxyGuard call No-Nonsense-Measurement Equipment. The same philosophy lies behind all OxyGuard equipment.

The product program has extended, and is still being extended, to include a wide range of meters, monitors, data loggers and probes, single and multichannel, for a wide range of uses in aquaculture, environmental care, waste water treatment and the industry in general. Dissolved Oxygen is still the prime parameter, but OxyGuard now also manufacture equipment for the measurement of oxygen in gas, temperature, pH and redox as well as oxygen dosing equipment.

Commander is a system that can control the operation of an entire fish farm. Commander includes some very advanced functions, but you only purchase what you need, so it is also ideal for smaller or less complicated systems. There is no limit to the size of a Commander system.

Pacific is a measuring, monitoring and control system designed for use in fish farms. It is both multichannel and multi-parameter, and forms a modular small-size complete system. A member of the Commander series of equipment, it can be used both as a stand-alone system or as part of a larger Commander system.

Convoy is a "small-scale" version of Commander designed to monitor, control and log details of water conditions during the transport of living fish. Convoy is designed for up to 16 probes.

OxyGuard Atlantic is a single channel oxygen meter with some advanced functions and a very reasonable price. It has set points, timers and output relays that can be linked to obtain the desired function, as well as a current loop output.

The OxyLog is a battery powered DO and temperature meter with data logging function. It is designed to be left in the field to measure and log values in streams, lakes and similar.

OxyGuard also have Displays and Alarms used on 4-20mA signals.
