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 your readings.

With its internal barometer, the instrument is able to automatically compensate for changes in barometric pressure so there is no need for charts, altitude information or external barometric pressure information. Salinity compensation in water allows direct determination of dissolved oxygen in saline waters.

Other features include measurement and methods for BOD (biochemical oxygen demand), OUR (oxygen uptake rate), and SOUR (specific oxygen uptake rate).

The HI 98186’s log on-demand features allows users to store up to 400 samples that can be later transferred to a PC with the HI?920013 USB cable and HI 92000 software.

An “Out Of Calibration Range Warning” can be activated to alert the user in the event that a reading is taken too far from the calibration’s periphery. A combination of dedicated and soft keys allows easy, intuitive operation in a choice of languages. Comprehensive GLP data is directly accessible by pressing the GLP key and a contextual Help menu can be access to obtain on-screen information and assistance about each feature at the touch of a button.

Designed for field use, this instrument can be easily operated with one hand and is housed in a rugged carrying case. The inductive charger can either be plugged into a standard 115V socket with the adapter included or a 12 VDC source, such as a car’s 12 V accessory outlet.
