HI 9143

HANNA HI 9143 Dissolved Oxygen Meter, Extended Range, HI9143

Field work can subject instrumentation to the inclemency of weather. Cold, rain, snow, dust and humidity can cause condensation to breech the housing, which eventually compromises the meter and rapidly diminishes its performance and life. HI 9143 and HI 9145 are designed for harsh outdoor applications, especially waste water treatment and fish farming. Simple on-site calibration requires no chemical solutions. Just expose the probe to air and press the CAL button. In a few minutes, the meter is calibrated and ready to use. Auto-calibration eliminates the need to use a screwdriver or other devices to adjust the reading.

The new and improved HI 9143 measure and display O² from 0 to 300%, 0 to 45 mg/L and temperature from 0 to 50°C.

 HI 9143 also supplies the user with compensations for salinity, altitude factors and compensate for the temperature effect.
