Description

Milwaukee MW106 MAX Waterproof pH/ORP/Temp Logging Portable Meter

The Milwaukee MW106 MAX Waterproof 3-in-1 pH/OPR/Temp. Logging Portable Meter is fast, reliable, tough and simple to operate.  It is ideal for brewers, wine makers, growers, labs, food processing, water treatment and many other applications with challenging pH measurement needs.

With up to 5-point calibration and 7 standard buffer choices (and two custom), the meter can be quickly calibrated to a higher accuracy compared with one or two-point calibration. The MW106 MAX meter is accurate to ± 0.002 pH., 8x more accurate than some alternative meters, and is IP67 Waterproof rated. 

Features:

  • Fast, easy-to-read results with a large duel level digital LCD readout
  • Extreme accuracy to ±0.002 pH | +/- 1 mV OPR | +/- 0.5°C (+/-1°F)
  • Extended range (-2.00 pH to 20.00 pH / -2.000 to 20.000 pH)
  • Lightweight and portable, IP67 rated
  • Simple, easy-to-use logging and USB download functions, manual or on demand up to 1,000 logs
  • Electrode diagnostics feature checks and displays the condition of the pH electrode
  • Easy measurement: just place the probe in the sample, gently stir and wait for the reading to stabilize
  • Simple push button, automatic up to 5-point calibration for increased accuracy
  • Gel-filled, double-junction, amplified rugged field design.  MA906BR/1 pH electrode is low maintenance with high accurate results and has a screw on cap to ensure proper storage
  • Built-in temperature sensor
  • 3 x 1.5V alkaline batteries with 200 hours battery life (battery included)
  • Auto shut-off feature to preserve battery energy
  • Alphanumeric LCD display messages for friendly, intuitive information, warnings and error messages
  • Internal clock date to keep track of different time dependent functions (i.e. calibration, timestamp, calibration time out)
  • 3-foot probe cables for extra flexibility when testing

CARE AND USE

pH meters usually start performing poorly because of problems with the probe, specifically the glass sensing bulb and the reference junction.  The glass bulb loses sensitivity with use and will eventually fail, which is true of all pH probes.  The reference junction is a small hole that allows the meter to compare the sample to a reference.  If the junction hole gets clogged, the pH probe will no longer function.

The life of your pH electrode can be extended in the following ways:

  1. Storage - The pH probe needs to be kept hydrated. Long periods of dry storage will damage the sensitivity of the probe. Allowing the probe to dry out may also result in the junction hole getting clogged. Storing in pH probe storage solution MA9015 or pH calibration buffers will help address both these issues. Do not store in tap water and DI water, this will damage the sensitivity of the probe.  The best way to store the probe is with the probe's cap filled with storage solution or calibration buffer and the cap tightened to prevent leakage. It is also recommended to store the electrode upright to further reduce the potential for leakage.
  2. Cleaning - Residue from the sample can impact the sensitivity of the sensing bulb and clog the junction. This is especially true if the sample has a lot of organic material. It is recommended to regularly soak your electrode in cleaning solution MA9016.
  3. Calibration - The pH sensing bulbs become less sensitive over time so make sure that you are calibrating regularly to keep your PRO pH meter accurate. Also, calibrate after cleaning or a long period of storage.
