The NEW OxyGuard portable CO2 Analyzer is a reliable and easy to use instrument that measures dissolved carbon dioxide in the water. The meter consists of a probe and a battery powered transmitter. The latter has a display showing the CO2 concentration and an analogue signal as output. The probe is, as standard, delivered with a 3 m cable. The transmitter has an on/off switch, “slope” and “zero” adjustments. A battery charger and calibration accessories are included. A version with built-in data logger is available.
The OxyGuard CO2 measures the CO2 gas pressure directly and is not affected by carbonates or other dissolved substances. It is therefore now possible, for the first time, to achieve simple, continuous direct measurements of the carbon dioxide in the water that affects the fish.
Previously, test kits, laboratory analysis or the detection of pH changes was used in an attempt to measure the CO2 in the water. All of these methods are subject to disturbance from the dissolved substances found in aquaculture water. The OxyGuard CO2 measures only the CO2 that affects the fish, which is the free dissolved CO2 gas. It is reliable and accurate.
For technical details see the Specifications page.
