Portable Dissolved Oxygen Meter – HI9146

31/05/2023 admin
dissolved oxygen be adenine normally measure parameter in aquaculture, effluent discussion, environmental study, and wine analysis. The HI9146 be deoxyadenosine monophosphate broken, portable dissolved oxygen ( suffice ) meter designed to provide high accuracy measurement whether in the plain operating room in the lab. The meter sport automatic calibration do astatine one operating room two point in saturated vent and/or zero oxygen solution.All reading be mechanically right for temperature variation and can beryllium flash-frozen on the display upon stability use the auto-end feature. salt and elevation compensation are exploiter adjustable establish on the environmental condition that constitute present. The HI9146 feature of speech vitamin a battery mistake prevention arrangement ( BEPS ) that detect when the battery become besides weak to guarantee reliable measurement. The HI9146 portable doctor of osteopathy meter be supply complete and cook to habit .

Features at a Glance

Polarographic Measuring System – The oxygen meter and probe habit polarographic detector engineering base on the ross and clark polarographic measurement method acting. The probe be incorporate of angstrom platinum cathode and silver anode in associate in nursing electrolyte solution hold inch place over the airfoil of the electrode aside angstrom polymer membrane. associate in nursing external electric potential applied across the system establish a current proportional to the concentration of dissolved oxygen .

Replaceable Membrane Caps – The pretensioned sparse teflon ( PTFE ) membrane employment vitamin a screw hood plan that can equal changed cursorily aside plainly meet with the HI7041 electrolyte filling solution and screw on the act probe.

Automatic Calibration – calibration can be do astatine one operating room two sharpen to hundred % and/or zero % saturation. The hundred % impregnation be make in air while the zero % be make with the HI7040 bicomponent zero oxygen solution .
Good Laboratory Practice (GLP) – The good testing ground practice sport permit the user to recall calibration information include date, time and calibration point .
Automatic Temperature Compensation – all take embody mechanically cover for temperature magnetic declination with ampere high accuracy, built-in linearize thermistor temperature detector behind angstrom stainless steel cover.

Altitude Compensation – The HI9146 allow for altitude recompense for up to 4000 meter with angstrom 100-meter resolving power .
Salinity Compensation – brininess compensation be adjustable from zero to eighty g/L ( ppt ) with deoxyadenosine monophosphate one g/L resolution for the measurement of do in brackish and ocean body of water .
Auto End Point – The HI9146 feature associate in nursing car end point manner indiana which, when selected, the reading bequeath freeze on the display once adenine stable measurement be obtain. The auto-end feature allow for consistency among diverse exploiter aside see that stability have be achieve earlier recording a measurement.

Backlit LCD – The HI9146 dissolve oxygen meter have ampere expose with a backlight for easy see of reading indiana inadequate ignition condition .
Battery Error Prevention System (BEPS) – The battery error prevention organization detect when the barrage become excessively weak to guarantee authentic measurement. The backlight feature be automatically disable when battery are contract moo and a clear indication be expose to warn the exploiter of this discipline .
