Waterproof Dissolved Oxygen Meter - Rugged, water resistant casing
- Simple, one point calibration
- ATC circuitry for high accuracy
The ever increasing demand for instant results from on-site analysis has created a constant need for portable, water proof meters. Measurements in the field can subject instrumentation to the inclemency of weather. Cold, rain, snow and dust associated with use in the field, can damage a meter, rapidly deteriorating its performance and life. HI 9142 is a rugged, water proof meter that solves these common problems of field use. It is very simple to use: calibration is performed with HI 7040 zero oxygen solution, while 100% calibration is done in air. There is no need to use chemical solutions or go through time consuming calibration procedures. The polarographic probe (HI 76407/4) will take measurements accurate to 0.3 ppm in minutes and is supplied with a 4 m (13') cable that allows measurements to be taken even in even hard to reach places.
HI 9142 is supplied complete with HI 76407/4 D.O. probe with 4 m (13') cable, 2 spare membranes, HI 7041S electrolyte solution (30 mL), calibration screwdriver, batteries, rugged carrying case and instructions. |
