DO Meter

The HI 98186 portable dissolved oxygen meter has extended ranges of up to 50 ppm or 600% saturation. This instrument includes barometric pressure measurement and calibration with a user-selectable unit (mmHg, atm, mbar, psi, kPa), as well as a 1- or 2-point temperature calibration. Salinity, pressure and temperature compensations enhance the precision of its readings.
