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.
