Calibration Procedure (2-Point):

For best results, calibrate frequently (once per every 30 tests OR once every 3 months).  Calibration is a cheap form of insurance to ensure that your readings are as accurate as possible.

.Dip the tip of the electrode (bottom 4 cm/ 1½") in pH 7.00 buffer solution at room temperature.  Allow the reading to stabilize.

Use a small screwdriver to adjust the pH7 trimmer until the display reads "pH 7.00".

Rinse the electrode with water and dip it in pH 4.00 (or pH 10.00) buffer solution. Allow the reading to stabilize.

With a small screwdriver adjust the pH4/10 trimmer until the display reads "pH 4.00" (or "pH 10.00").

• Calibration is now complete.




This unit can be used for more than just testing water!

This is a great tool for when you need to test your pond, aquarium or Hydroponic pH. It is a fast and accurate meter. What you save in buying drop type test kits will more than pay for this meter! And those type kits are not usually very accurate. You will NEVER have to GUESS which color the ph Strips are closest to! It is fast and simple to use. Just dip it in the pond or aquarium and read the reading on the digital display in just a few seconds.

Use if for chemicals, water based products, industrial fluids, food products - whatever you think you want to test, you can test it (as long as it's not too hot, too hard, too gooey, too sticky or too dry).

Calibration Fluids! 

Don't forget to add a few pH Buffers to the order!  Keep your pH Meter in tip-top shape by calibrating periodically!  This unit needs a 2-point calibration, so the question is: which buffer solutions do I need?  For water based samples, use 7 and 10.  For unknown samples use 4 and 10.  The key is to steer the units calibration towards the ranges of your samples.  Testing acids, use 4 and 7.  Testing bases (caustic/alkaline) use 7 and 10.  Unknown samples 4 and 10.
