The ever increasing demand for instant on-site analysis results has created a need for innovative and rugged portable, waterproof meters. The HI-9142 is a simple to use DO meter with Polarographic probe.

Field work can subject instrumentation to the inclemency of weather. Cold, rain, dust and humidity can cause condensation to breech the housing. The water resistant housing of HI-9142 solves many of the problems of field use.

Calibration is performed with HI-7040 zero oxygen solution, while 100% calibration is done in air.

The Polarographic probe (HI-76407/4) is accurate to 0.3 ppm and is supplied with a 4 m cable that allows measurements to be taken even in hard to reach places.
