JENWAY 9200 PORTABLE DISSOLVED OXYGEN METER
The Model 9200 Dissolved Oxygen Meter, part of the Premier Portable range, is a fully specified unit combining ease of use and robust construction. Utilising a Clark type polarographic membrane electrode optimised for both speed of response and the ability to withstand the rigours of portable use, dissolved oxygen measurements can be made either as % saturation or as concentration in mg/l (ppm).
The DO2 sensor incorporates a precision temperature measuring device which determines and displays the temperature of the analyte and automatically corrects for the changes in membrane permeability and oxygen solubility which occur with variations in temperature.
Calibration is a simple push-button operation carried out in the % saturation mode with clear instructions given via the graphics display.
Salinity correction is necessary when concentration measurements are being made in brackish or saline environments. Provision is made on this instrument for this correction to be made using salinity (g/l) or conductivity data. The Model 9200 Dissolved Oxygen Meter is equally at home in a laboratory environment and powerful in-built consumables is dedicated to the Biochemical Oxygen Demand (BOD) determination.
The Model 9200 Dissolved Oxygen Meter offers the facility to download data held in memory to a printer or computer. These units incorporate a bi-directional infra-red link which ensures that the waterproof characteristics of the products can be maintained at all times. The infra-red link operates in conjunction with the optional interface cradle, allowing data interchange without the inconvenience of plugs and sockets.
Other Dissolved Oxygen Meters available from Jenway are the Model 970 Portable Dissolved Oxygen Meter, the Model 9150 Premier Portable Dissolved Oxygen Meter and the Model 9500 Laboratory Dissolved Oxygen Meter.
Also available from Jenway in the Premier Portable range are the Models 3150 pH Meter, the Model 3205 pH/Ion Meter and the Models 4150 and 4200 Conductivity Meters.
