Features at a Glance :
Polarographic Measuring System – The oxygen meter and probe use polarographic sensor technology based on the Ross and Clark polarographic measurement method. The probe is comprised of a platinum cathode and silver anode in an electrolyte solution held in place over the surfaces of the electrodes by a polymer membrane. An external voltage applied across the system establishes a current proportional to the concentration of dissolved oxygen.
Replaceable Membrane Caps – The pretensioned thin polytetrafluoroethylene (PTFE) membranes employ a screw cap design that can be changed quickly by simply filling with the HI7041 electrolyte fill solution and screw on the DO probe.
Automatic Calibration – Calibration can be performed at one or two points to 100% and/or 0% saturation. The 100% saturation is done in air while the 0% is done with the HI7040 bicomponent zero oxygen solution.
Good Laboratory Practice (GLP) – The Good Laboratory Practice feature allows the user to recall calibration information including date, time and calibrations points.
Automatic Temperature Compensation – All readings are automatically compensated for temperature variations with a high accuracy, built-in linearized thermistor temperature sensor behind a stainless steel cover.
Altitude Compensation – The HI9146 allows for altitude compensation for up to 4000 meters with a 100-meter resolution.
Salinity Compensation – Salinity compensation is adjustable from 0 to 80 g/L (ppt) with a 1 g/L resolution for the measurement of DO in brackish and sea water.
Auto End Point – The HI9146 features an auto endpoint mode in which, when selected, the reading will freeze on the display once a stable measurement is obtained. The auto-end feature allows for consistency among various users by ensuring that stability has been achieved before recording a measurement.
