Disinfecting The Probe; Changing The Module; Changing Battery - TESTO 206 Instruction Manual

6.4 Disinfecting the probe

The measuring instrument should not be exposed to disinfectant
for an excessive period of time. Using the TopSafe protective
case can reduce the risk of incompatibility.
1. Wet a paper towel with disinfectant.
2. Gently dab the probe with the disinfectant, avoid rubbing.
3. Ideally, regenerate the probe in electrolyte gel for 12 hours
before carrying out another measurement. (Using alcoholic
disinfectants removes water from the glass membrane)
4. After each disinfection, carry out calibration with the buffer
solution. (see 5.5 Calibrating the instrument)
