According to Hanna Instruments , measurements in the field can subject instrumentation to the inclemency of weather.

Cold, rain, snow, dust and humidity, associated with use in the field, can cause condensation which may damage a meter, rapidly deteriorating 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 and HI 9145 measure and display O2 from 0 to 300%, 0 to 45 mg/L and temperature from 0 to 50 °C. In addition to the features of HI 9145, HI 9143 also supplies the user with compensation of salinity and altitude factors. Both meters compensate for the temperature effect.

HI 9143 is supplied complete with D.O. probe HI 76407/4 with 4 m (13’) cable, 2 spare membranes, electrolyte solution HI 7041S (30 mL), batteries, rugged carrying case and instructions.
