The Model 9200 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 9200 utilises a Clark type polarographic membrane electrode optimised for both speed fo 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 and the reported results are influenced by atmospheric pressure and depth unless appropriate compensation is made. The 9200 allows these values to be entered through the menu options.

Calibration is simple keypad operation performed in the % saturation mode. Clear instructions are given via the graphics display.

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.

The 9200 is equally at home in the laboratory environment and is suitable for B.O.D. (Biolchemical Oxygen Demand dtermination. The optional B.O.D probe and associated components are designed to faciltate the 5 day B.O.D. test as defined in ISO 5815. The kit includes adaptors, allowing use with the many B.O.D. bottle configurations commonly available.

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).
