Product Description

The HI 9143W 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 0.00 to 45.00 mg/L O2 0.0 to 300.0% O2, 0.0 to 50.0 degrees C (+ or - 1.5% FS (O2), 0.5 degrees C) and a resolution of 0.1 mg/L, .1% O2, 0.1 degree C. The meter operates from 0 to 50 degrees C (32 to 122 degrees F), and automatically compensates for temperature (ATC) from 0 to 30 degrees C. Salinity and altitude values can be entered to allow the meter to compensate or these variables . 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.
