For the PH600, a light brushing with a toothbrush every week will be enough, and every month with a bath in a sachet of cleaning liquid (M10016).
The PH600 meter has a scale from 0.0 to 14.0, Resolution of 0.1pH; manual one-point calibration (with screwdriver), 3 x 1.5V button cell.
The CD611 (EC) meter has a scale from 0.0 to 20.0 mS, resolution 0.1 mS, manual one-point calibration (with screwdriver), 3 x 1.5V button battery.
Operation: PH600
Don't be surprised to see white crystals surrounding the head of the meter. This is normal for a pH electrode. These salts will dissolve with water.
Remove the black protection and turn on the meter.
Immerse it to the limit and wait for the data to stabilize.
After use, pass the electrode with water to keep it clean.
Preserve the electrode by putting a few drops of MA9015 storage liquid or ph 7.0 calibration liquid on the cap.
Always replace the cap after use.
DO NOT USE distilled or deionized water for storage.
Large reading differences of (~0.5 pH) may be due to need for calibration, dry electrode or low batteries
