OxyGuard Handy Polaris Meters

The OxyGuard Handy Polaris hand-held meter makes it easy to measure dissolved oxygen and temperature. The flat foil push buttons are easy to operate and the instrument is always ready to use – just press the “on” button and measure. Dissolved oxygen values are shown both in mg/l (ppm) and % saturation – you can choose which parameter is shown in large figures. Measurements are compensated for changes in barometric pressure. Functions such as automatic calibration and self-check of the probe and meter combine with the well-known accuracy, reliability and low maintenance needs of the OxyGuard Handy series to make an instrument that will serve you well for many years to come. The Handy Polaris 2 extends the usability of the Polaris, by taking all it's great features whilst adding datalogging and the capacity to download your data to the PC, through the USB Link.

Finally the OxyGuard Handy Polaris TGP allows users to measure Total Gas Pressure, showing values as percent saturation when used for Dissolved Oxygen, and in Volume Percentage when uses for measuring total gas pressure.

YSI Pro Solo

YSI ProSOLO ODO Optical Dissolved Oxygen Meter

An evolution of the Professional Series water quality meters, the ProSolo DIGITAL handheld replaces the ProODO as YSI’s most advanced optical dissolved oxygen field meter. Paired with the latest optical DO and temperature (ODO/T) probe, the ProSolo benefits from years of expertise in cutting-edge dissolved oxygen technology.

The ProSolo handheld is the direct replacement to the ProODO Optical Dissolved Oxygen handheld, and is fully compatible with ProODO cables and ProOBOD probes. The ProODO handheld will be discontinued on Dec. 31, 2018.

Order with an ODO/T probe assembly for a complete sampling system.

Portable CO2 Meter

OxyGuard Co2 portable

The OxyGuard CO2 gives simple, continuous and direct measurements of the amount of carbon dioxide in the water that will affect the fish.

The OxyGuard CO2 Portable is a reliable and easy to use instrument that measures the free dissolved carbon dioxide concentration directly in the water. The CO2 concentration is shown on the display, and there is an analogue output. A version with built-in data logger is available.

OxyGuard Handy Salinity

A handheld measuring instrument for salinity with measuring range 5-50 PPT

The Handy Salinity is a hand-held instrument specially designed for aquaculture use. Factory calibration and automatic temperature compensation make it very easy to use. The display shows the salinity directly. Temperature is also measured and shown in the display.
The instrument incorporates automatic check functions to ensure reliability. The probe is designed to be as trouble-free as possible, with features specially suited for aquacultural use.

OxyGuard Handy Atmosphere

OxyGuard Handy Atmosphere

A hand-held meter designed to measure oxygen in the air.

Signal processing is performed using a microprocessor, which gives a number of advantages. Just as with other Handy instruments you can simply switch on and measure, but the use of microprocessor technology enables measurements to be supported by a range of advanced functions designed to make things even easier for you:

• Automatic Calibration
• Choice of Language
• Oxygen, temperature, barometric pressure. • Automatic self-check
• Automatic Probe Check
• Barometric Pressure Compensation
• Extremely long battery life

pH Meter

OxyGuard Handy Redox/pH

The OxyGuard Handy pH is a hand-held, pocket-size pH or Redox meter designed for use in demanding wet environments.

The meter itself and the electrode assembly are waterproof. This instrument does not suffer from the classical problems associated with pH meters – the Handy pH is sealed so that water cannot enter the top of the electrode or the electronics. You can drop it into the water without damaging it! In the Handy pH, these advantages are combined with microprocessor technology to give an instrument that is exceptionally easy to use.
