HI9142 Manual Calibration Dissolved Oxygen Meter • Automatic Temperature Compensation (ATC) • One or two-point calibration • Waterproof 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.
