pH meter PH-2011 ATC with calibration solution

pH meter PH-2011 ATC with calibration solution
pH meter PH-2011 is designed for measuring the value of "pH" in the range of 0.0 to 14.0 non-aggressive and non-flammable liquids, which must not be under electrical voltage. Use other than that specified above could damage this unit or cause injury. The device is designed for orientation measurements in the home. It is not intended for measurement, eg in areas where measurement with a calibrated instrument is required for legislative reasons.

Package contents:
1 × pH meter
1 × screwdriver
2 × calibration (4.0 and 6.86pH) - Buffer


Calibration:
- Dissolve the contents of the Buffer pH 4.0 bag in 250 ml of distilled water - container1
- Calibrate according to the pH value on the bag using a screwdriver on the back
- Dissolve the contents of the Buffer bag pH 6.86 in 250 ml of distilled water - container2
- Calibrate according to the pH value on the bag using a screwdriver on the back until the value on the LCD is equal to the value on the bag (pH 4.00 or pH 6.86)

Notice:
Supplied without batteries.
A white coating may appear on the product, this is the remainder of the calibration solution from the output control.
