Growth Technology pH 4 Calibration 300ml

Growth Technology pH 4 calibration is used to calibrate pH meters.

Normally, calibration fluid pH 7.0 is also used when calibrating.

* You should calibrate your pH meter regularly to ensure accuracy from the meter.
* We recommend calibrating your pH meter before first use.
* And then about once a month.

Typically, you calibrate like this:

1. Immerse the electrode in the calibration fluid pH 7 at a temperature of 25°C and shake it gently.
2. Allow the reading to stabilize.
3. Turn the calibration screw on the meter until the reading corresponds to the value of the solution.
4. Immerse the electrode in the calibration solution marked with pH 4 and follow the same procedure.
5. Wait for the meter to show the correct measurement.
