The use of calibration, cleaning and storage liquids is essential for the proper use of your meters.

In addition to good use, the electrode also benefits by having a longer useful life and working more efficiently.

To calibrate with the EC12880 calibrator buffer, 230ml bottle, pour up to 1cm of calibrator liquid into a glass. Turn on the meter, put the tip of the probe or electrode in the glass. Then proceed to calibrate it:

Calibration can be manual or automatic.

In case of manual calibration with the EC12880 calibrator buffer in a 230ml bottle, turn on your meter, put the meter or the electrode inside the glass, shake slightly to facilitate the reading of the buffer by the meter, and, with the help of the calibration screwdriver or of the calibration wheel (depending on the model) adjust the data on your screen to the data indicated in the buffer.

In case of automatic calibration with the EC12880 calibrator buffer, 230ml bottle, follow the instructions in your meter's manual. The way to calibrate will depend on each type of meter.

Below, we indicate the guidelines for good maintenance of your measurement equipment.

The case: Are your PH and EC meters working poorly, or not working, or slow, or not calibrating?

The question is: what to do to make your meters work well, and so that they last long?

1ST TIP: CHECK BATTERIES

• It is very important to have an accurate and fast measurement.
• To measure the power of the batteries, use a millimeter in the DCV 20 position – A battery that does not have the indicated power will be considered dead and must be replaced.
• Example: 1.5V button battery. New, it will have a power of 1.56V, and when it drops below 1.50V, that is, to 1.49V, it is dead.

2ND TIP: CLEANING THE ELECTRODE

• PH: In case your PH meter is 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 not usually advised, light brushing with a soft-haired toothbrush improves the quality of the measurement.
• After cleaning, your PH meter will also do well to soak for a couple of hours in PH storage liquid (MA9015).
• A bath in cleaning liquid is recommended (On M10030B or MA9016 bottle).
• EC: In EC, little maintenance is usually given to an electrode. But in the event that your EC measurement does not reach calibration, you can leave the probe in 1 cm of 90º alcohol for 2 minutes, to dissolve the salts stuck to the irons, which possibly prevent correct electroconductivity.

STORAGE TIPS:

• PH: For a portable PH meter, it is very important to store it in humidity (put a damp sponge with MA9015 storage liquid) – (Never put distilled or deionized water)
• EC: Store dry, without further ado.
• Tips for calibration fluids (buffers):
• Calibration liquids are normally single use.
• Especially in conductivity, which are immediately affected by evaporation, which modifies the concentration of salts

In PH, to calibrate at two points (PH4.01 and PH7.01), try to pass the electrode through tap water when leaving calibration at pH7.01, so as not to contaminate the PH4.01 buffer. Another thing, the calibration envelopes, after use, can be used again a few times, provided they are closed hermetically (with a seal).

AVOID FALLS:

• For EC PH meters, it is advisable to avoid dropping them to the ground, which can permanently damage the LCD screen. For this reason, in Milwaukee, we recommend the use of a carrying case (ask us for it!)
• Also, to avoid falling into water, it is advisable to measure from a glass. In addition to ensuring that your meter does not fall into the water, it will also give your meter time to stabilize and thus give a more accurate measurement.
