Automatic Temperature Compensation
Affordable and efficient
DO probe and carrying case included
The ever increasing demand for instant on-site analysis results has created a need for innovative and rugged portable, 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. The rugged, waterproof housing of the 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 ( 13' ) cable that allows measurements to be taken even in hard to reach places.
