Milwaukee Sonda PH para Tuberia MA905 (Cable 3m)

Milwaukee 3m cable PH probe for MA905 tube


Milwaukee has a wide range of pH electrodes, ORP, Conductivity and other special sensors to meet all your specific needs. Finding the right electrode for a specific application is a very important task and in order to solve this selection problem it is important to consider the following: electrode body, construction and reference junction.

Maintenance advice, storage of your PH and EC electrodes

Do your PH and EC meters work poorly, or do they not work, or are they slow, or do they not calibrate?

What to do to make your meters work well, and to last a long time?

First tip: Check batteries - It is very important to have a precise and fast measurement.

To measure the power of the batteries, use a multimeter in position DCV 20 - A battery that does not have the indicated power, will be considered as dead, and to change.

Example: 1.5V button battery. New, it will have a power of 1.56V, and when it drops below 1.50V, or 1.49V, it is dead.

Second tip: Cleaning the electrode

PH: In case your PH meter goes slow or does not measure, or does not calibrate, or the data dances and does not stay fixed. Most likely, the electrode is dirty. Also, although it is not usually advised, a light brushing with a toothbrush with soft hair improves the quality of the measurement.
After cleaning, it will also do well for your PH meter to soak a couple of hours in storage liquid for PH (MA9015).
We recommend a bath in cleaning liquid (About M10030B or boat MA9016)
EC: In EC, little maintenance is usually given to an electrode. But in the case that your EC measurement does not reach calibration, you can leave the probe in 1 cm of alcohol 90 ° for 2 minutes, to dissolve the salts attached to the irons, which possibly prevent the correct electroconductivity. Storage Tips:
PH: For a portable PH meter, it is very important to store in moisture (put a wet sponge of storage liquid MA9015) - (Never put distilled or deionized water)
EC: Store dry, without more.
Tips for calibration fluids (buffers):

The calibration liquids are usually single-use.
Especially in conductivity, which are immediately affected by evaporation, which modifies the concentration of salts
In PH, to calibrate in two points (PH4.01 and PH7.01), try to pass the electrode through tap water when leaving calibration at pH7.01, in order not to contaminate the PH4.01 buffer. Another thing, the calibration envelopes, after use, can be reused a few times, provided they are sealed (with a seal).
Avoid falls:
For EC pH meters, it is advisable to avoid ground drops, which can permanently damage the LCD screen. Therefore, in Milwaukee, we recommend the use of the transport case.
Also, to avoid falls in the water, it is advisable to measure from a glass. In addition to ensuring that your meter will not fall into the water, also, it will give your meter time to stabilize and thus give a more accurate measurement.
