Portable type DO Meter

$0.00

HI 9146 is a water-resistant, microprocessor-based, Dissolved Oxygen meter that measures up to 300% saturation or 45 ppm (mg/L) with automatic temperature compensation (ATC) and automatic calibration.  It has been developed for DO and temperature measurement in water, wastewater, wine and applications such as fish farming.

D.O. measurements can be displayed in parts per million (ppm=mg/L) or in % of saturation.  The temperature range is indicated in Celsius from 0 to 50°C with 0.1 resolution.  This meter also allows manual compensation of altitude up to 4000 m and salinity values.  The polarographic probe, supplied with the instrument, is provided with a protective cover for the membrane.  A HOLD button allows the user to freeze readings on the LCD.  HI 9146 can be powered with batteries (with low battery indicator) or through a 12 VDC adapter.
