HI9146 In-line Dissolved Oxygen and Temperature Meter for Wastewater

Producer: HANNA Instruments

SKU: HANNA-HI9146 Category: Hanna experimental measuring equipment

Direct Dissolved Oxygen and Temperature Meter in Wastewater

– Measure dissolved oxygen from 0.00 to 45.00 ppm (mg/L), 0.0 to 300.0% saturation

– Automatic calibration 1 or 2 points.

– Temperature compensation, altitude and depth compensation automatic salt

– Supplied with measuring device and full accessories in a sturdy carrying case without needing to purchase anything else.

– Convenient and sturdy suitcase for carrying the device

– Specialized in wastewater, rivers and lakes.

– Multiple electrode cable length options:

+ HI9146-04: long cable electrode 4m

+ HI9146-10: electrode long cable 10m

hi9146_angle-2100x2099-71ca02b3-3fcd-4c5f-b6c0-6d566104e1fa LCD COLOR DISPLAY

HI9146 Has a backlit display for easy reading of results in low light conditions.

GLP

The GLP feature allows for review of calibration information including date, time, and calibration points.

AUTO END

HI 9146 has an automatic hold mode that freezes the reading on the display when the measurement is stable.

POLAROGRAPHIC ELECTRODE

The meter and probe use polarographic sensor technology based on the Ross and Clark polarographic measurement method. The probe consists of a platinum cathode and silver anode in an electrolyte solution held on the electrode surface by a polymer membrane. Oxygen diffuses through the membrane and establishes a current proportional to the concentration of dissolved oxygen.

AUTOMATIC CALIBRATION

Calibration can be performed at one or two points to 100% and/or 0% saturation. The 100% saturation is performed in air and the 0% is performed with HI 7040 oxygen-free solution.

EASILY REPLACEABLE MEMBRANE LID

Lid HDPE membrane uses a screw cap design that can be quickly replaced

Replace periodically at least once a month.

Remove when not in use

hi76407-4f-2100x2100-7d7fd828-a4ef-422f-ad9f-d506f3c2acab-1

ELECTRODE PROTECTION TUBE

The device comes with a protective tube to protect the electrode tip from impact when measuring in the field such as rivers, lakes, and wastewater tanks.

TEMPERATURE, ALTITUDE AND SALINITY COMPENSATION AUTOMATIC

HI9146 Allows altitude compensation up to 4000 meters with 100 meter resolution.

Adjustable salinity compensation 0- 80 g/L (ppt) with 1 g/L resolution for DO measurement in brackish and seawater
