Digital Ph meter for swimming pools and hot tubs

Digital pH meter

The pH value should be between 7.0 - 7.4 * Adjust with pH Plus or pH Minus.

• A high pH value results in poor chlorine disinfection, skin irritation, limescale and turbidity.
• Low pH results in aggressive water that wears out equipment and irritates eyes and mucous membranes.

Before using the pH meter, carefully remove the black top with the on/off button, see picture.
Poke the "piece of paper" so the battery makes contact.

Instructions for use

• Remove the protective cap.
• Put the meter on top
• Fill a clean, dry glass with 3-4 cm of bath water about 15-20 cm from the surface.
• Immerse the instrument in the water 20-30mm. Stir slowly until the pH value stabilises.
• Read the pH value.

• Read and switch off the meter. Put on the electrode cover. A small damp sponge in the cover is useful. It should not dry.

CALIBRATION
    - Immerse the tester up to the maximum immersion level in pH 6.86 buffer solution
- Allow the reading to stabilise and using a small screwdriver adjust the calibration trimmer to read 6.9.
Calibration is now complete.
