The Model 9150 Dissolved Oxygen Meter is designed and constructed to resist the harshest of field, laboratory and industrial environments. The whole system is waterproof to IP67, and if dropped into water will float. These products are ideal for on-site water quality measurement in a multitude of customer applications.

The 9150 utilises a Clark type polarographic membrane electrode optimised for both speed oF response and the ability to withstand the rigours of portable use. Measurements can be performed as either % saturation or as concentration in mg/l (ppm). The sensor incorporates a precision temperature measuring device which determines and displays the temperature of the analyte. Automatic correction is made for the changes in membrane permeability and oxygen solubility which occur with variations in temperature.

The sensor measures the partial pressure of oxygen. The reported results are influenced by atmospheric pressure and depth unless appropriate compensation is made. The 9150 has both compensated and uncompensated modes of operation.

Salinity correction is necessary when concentration measurements are being made in brackish water or saline environments. Provision is made on the 9150 for this correction using salinity (g/l) or conductivity data.

High quality waterproof connectors (to IP67) allow rapid interchangeability of electrodes, whilst maintaining waterproof integrity. The connector incorporates a locking ring to guard against accidental disconnection or ingress of moisture.

Power is provided by 3AA size batteries giving typically 100 hours of use. An operator selectable auto shut-off feature ensures battery life is maximised. Automatic low battery warning is given when remaining battery life is approximately 5 hours (@ 20C).
