Keep your Bluelab pH and EC Meters Clean and Accurate

Being able to test the pH and EC of your feedwater is vital in ensuring your plants are fed properly and stay happy. Underfeeding or overfeeding or pH problems in the feed water means that your plants will suffer. Bluelab pH and EC meters have been the choice of growers for a very long time. They are tough, accurate and very reliable. However, to maintain their accuracy and reliability they need to be cleaned and calibrated periodically. This kit contains everything you need to clean and calibrate your Bluelab pH and EC meters.

How the Bluelab Cleaning and Calibration Kit Works

Bluelab meters are great for growers. They reliably assist the gardener to properly mix and periodically test their nutrient solutons. Although Bluelab pH and EC meters are known for their build quality and ease of use, they are actually highly sensitive and accurate pieces of scientific equipment. Just like with all pH and EC meters, through use, debris and dirt can build up on the probes. This can cause the meter to give inaccurate readings and also reduce their lifespan. To maintain the accuracy and lifespan of a Bluelab meter the probes needs to be kept clean and the meter needs to be recalibrated from time to time. This care kit contains all the solutions and cleaning tools you'll need to clean and check the calibration of any Bluelab meter.

How to Use the Bluelab Cleaning and Calibration Kit

EC Meter Cleaning and Calibration: Remove and shroud or protective cover around the meter probe. Apply a small quantity of the EC meter probe cleaner from the tube to the surface where the probes are located. With the chamois cleaning tool held flat against the surface, rub the chamois cleaning tool against the surface and the probes. For carbon probes (such as in the Bluelab Truncheon) keep rubbing until a little of the black carbon is seen in the cleaning liquid. After cleaning, rinse the probe off in running water and refit the shroud or protective cover. The cleanliness of the probes can now be checked by testing whether it is back in calibration. To check the calibration, open a sachet of 2.77 EC and pour it into one of the small plastic pots. Dip the probe into the pot. Your Bluelab Meter should read an EC of 2.8. If it does not then further cleaning may be required. Discard the calibration solution after use and use a fresh sachet the next time.

pH Meter Cleaning and Calibration: Remove the toothbrush-type cleaning tool from it's protective cover and wet it with pH probe cleaning solution form the tube and rub the bristles over the pH probe (small glass dome) several times. Re-apply cleaning solution to the toothbrush and rub the probe as many times as neccessary until the probe is clean of and dirt or debris. After cleaning, rinse the probe with fresh water and store using the KCL probe storage solution from one of the sachets. DOnce clean, re-calibrate your pH meter. Open one sachet of pH 7.0 and pour into one of the small pots Follow the instructions for your meter to calibrate it at pH 7.0. Rinse the probe with fresh water. Next, open one of the pH 4.0 sachets and pour into one of the clean, dry pots. Dip the Meter into it and follow your meter instructions to calibrate your meter to pH 4.0. Again, rinse the probe in fresh water afterwards. Store your meter using the KCL storage solution.
