The ever increasing demand for instant
on-site analysis results has created
a need for innovative, rugged,
portable and waterproof meters.
Field work can subject instrumentation to
the inclemency of weather. Cold, rain, snow,
dust and humidity can cause condensation
to breech the housing. Once the housing has
been compromised, the meter is susceptible
to diminishing performance and life span.
The rugged, waterproof housing of the
HI9142 solves many of the problems of
"eld use.
Calibration is performed with
HI7040 zero oxygen solution, while
100% calibration is done in air.
The polarographic probe (HI76407/4) is
accurate to 0.3 ppm and is supplied with a
4 m (13’) cable that allows measurements
to be taken even in hard to reach places.
