pH value and temperature are key parameters for guaranteeing the quality assurance of products in the food sector, in the cosmetics industry, in the sanitary and HVAC sector, etc. With the testo 206-pH1 starter set, you can get started straight away with measuring the temperature and pH value in liquids (e.g. in drinking or heating water).

Benefits of the pH/temperature measuring instrument set at a glance

The testo 206-pH1 temperature and pH measuring instrument boasts the following features:

  • The pH probe is ideal for measurements in liquids. The temperature sensor ensures precise, fast temperature compensation, and therefore precise pH measurement
  • The pH probe is maintenance-free, leak-proof and insensitive to dirt thanks to the gel electrolyte in the probe
  • The dual wall diaphragm of the pH probe guarantees quick, reliable pH measurement
  • Simultaneous display of pH value and temperature on the clear display
  • Automatic final value recognition (auto hold): the reading is automatically held once it is stable
  • The measuring instrument enables 1-, 2-, or 3-point calibration – calibration dosing bottles for pH 4.01 and 7 are included in the set

With the included accessories, you are ideally equipped for measuring pH:

  • TopSafe protective case: this is dishwasher-safe, hygienic and protects the measuring instrument from dirt, water and shock. Safely stored in the protective case, the pH measuring instrument is waterproof in accordance with protection class IP 68
  • Storage cap with gel: the storage cap, which is filled with gel electrolyte and attached to the pH probe, is used to store the probe between measurements
  • Calibration dosing bottles: both pH calibration solutions, pH 4.01 and 7, are DAkkS-certified and facilitate calibration of the pH probe. The pH probe is calibrated in the integrated dosing aperture of the calibration dosing bottle. This guarantees economical use of the calibration solution
  • Belt/wall bracket: used for storing the measuring instrument on the wall or on a belt
  • Robust aluminium case: this ensures safe transport of all the measuring equipment
