The Bench Meter 0,00 à 45,00 mg/L (ppm) is one of Milwaukee’s most popular meters with its reliable and fast operation as well as its accuracy.

The Milwaukee MW190 MAX DO Bench Meter is preferred by people looking for lab-level accuracy without the high cost. The Milwaukee DO Meter is popular with everyone from field biologists, educators, fish farmers, koi pond owners, education, water treatment plants and laboratories.

DESIGN FEATURES

  • Fast, easy-to-read results with large digital LCD readout.
  • Repeatable, accuracy to ±1.5% FS.
  • Lightweight and has a small benchtop footprint.
  • Single offset or dual point slope with open air 100% saturation calibration.
  • Altitude and Salinity compensation.
  • Automatic temperature compensation.
  • Uses MA845 (included) reinforced polarographic probe with an oxygen-permeable polytetrafluoroethylene (PTFE) membrane sensor
  • 5 o-rings, membranes, and one protective cap included
  • 2-meter probe cable for extra flexibility when testing
  • Logging up to 50 samples.
  • 12 VDC power supply.
  • Easy RS232/USB opto-isolated
  • Complete with DO probe, initial calibration solutions and cables.

CARE AND USE
PROBE PREPARATION CALIBRATION PROCEDURE

D.O. Probes are shipped dry:  To hydrate the probe and prepare it for use, connect it to the meter and proceed as follows:

1. Remove the red and black cap. This cap is used for protection during shipping.
2.  Wet the sensor by soaking the bottom 2.5 cm of the probe in the electrolyte (MA9071) for 5 minutes.
3.  Rinse the membrane (supplied with a meter) with electrolyte solution while shaking it gently.  Refill with clean electrolyte solution.
4.  Gently tap the sides of the membrane with the fingertip to ensure that no air bubbles remain trapped.  To avoid damaging the membrane, do not tap the membrane directly on the bottom.
5.  Place the O-Ring (supplied with membranes) properly inside the membrane cap.
6.  With the sensor facing down, screw the cap clockwise.  Some electrolyte solutions will overflow.
7.  Turn the unit on and use on/off key.
8. All LCD tags are displayed and a beep is heard while the instrument performs a test.
9.  The “COND” message will be displayed for about 45 seconds to inform the user that the probe is in auto-conditioning mode (automatic polarization).
10.  Once “COND” disappears, the probe is polarized and the instrument can be calibrated.

2. Calibration Offset Procedure

1.  Remove the clear protective cap.
2.  Submerge the probe in MA9070 zero oxygen solution and stir for about 2-3 minutes.
3.  Press CAL. The “WAIT” tag will blink on the LCD until the reading is stable.
4.  When the reading is stable, “READY” & “ACCEPT” tags are blinking.  Press ACCEPT to confirm the “0.0%” D.O. calibration.

NOTE:  When the instrument is not in use, place the CLEAR plastic cap (supplied with probe) over the membrane.

Extra tips

Watch for the membrane having wrinkles or stretch marks. If you see wrinkles, replace them with a new membrane.
Always use fresh electrolyte solution (MA9071).
