The HI 9142W is a waterproof oxygen meter with a reinforced plastic polarographic probe and a 4 m (13’) cable for difficult-to-reach field applications. Calibration is manual at one or two points with included 7041S electrolyte solution, while 100 percent calibration is done in air.
The meter has a range of 0.0 to 19.9 mg/L (+ or - 1.5 F.S) and a resolution of 0.1 mg/L. The HI 9142W operates from 0 to 50 degrees C (32 to 122 degrees F), and automatically compensates for temperature (ATC) from 0 to 30 degrees C. Dimensions are 196 x 80 x 60 mm (7.7 x 3.1 x 2.4"), with weight 500 g (1.1 lb.).
Dissolved oxygen meters are used in a variety of applications to monitor the amount of oxygen present in water. Applications include sewage and water treatment plants, pollution control, fish farms, and various types of manufacturing.
