Product Description

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

The professional pH measuring instrument for drinking water analysis

With the development of different, breakproof probe geometries, Testo is making available special solutions for liquid as well as for viscoplastic substances. The leakproof storage solution is also new. pH probes must be stored in moist conditions, when not in use, in order to prevent the glass membrane coating around the measurement electrode and the diaphragm from drying out.

Pure water alone should not be used since water would release the conducting components contained in the probe electrolytes. A potassium chloride solution is usually used for this purpose. As with every liquid, it can leak which, particularly in the food branch, can lead to contamination of raw foodstuffs or products. Testo, with its new gel storage, has eliminated this disadvantage. The potassium chloride solution is available in a container in gel form. What doesn’t drip can’t leak!

The professional pH measuring instrument for the food sector

Measurement of the pH value plays an important role in many areas. Anywhere where

there are chemical and biochemical reactions,the pH value has an important indicator function.

Compact pH measuring instrument for measuring liquids. Built-in temperature probe for efficient temperature compensation. Automatic recognition of a stable reading makes it easier to measure. The "TopSafe" case included makes the instrument ideal for outdoor applications or

for use in tough industrial conditions.

Your benefits

• Versatile, accurate pH measuring instrument

• Not affected by dust or dirt thanks to the TopSafe protection case

• Maintenance-free gel electrode

• Built-in temperature probe

• 2 line display

• Automatic full scale value recognition

• 1, 2, or 3 point calibration possible

pH measurement in the cosmetics industry

The pH value is a crucial factor when it comes to assessing the quality of cosmetic products. Cosmetic products which are too acidic can cause skin irritations or rashes. The pH value of the skin is normally between 5 and 6.5 thanks to its natural protective acid mantle. “Skin-neutral” cleansers are actually slightly acidic and can support the skin's protective acid mantle, which is particularly important for people with sensitive skin. On the other hand, alkaline cleansers could encourage the skin's process of replenishing its natural oils.

The pH value of cosmetics must therefore be monitored, controlled and, if necessary, adjusted right from the production stage, so that the end product has the required value. The testo 206 one-hand pH measuring instrument helps you to do this through:

- Direct measurement in process for fast assessment of the pH value

- Three different versions of the product – depending on the medium in which the measurement is being made (e.g. liquid, paste-like, etc.)

- Robust, waterproof and dishwasher-safe “TopSafe” protective cover (protection class IP68) to meet strict cleaning requirements in the pharmaceutical sector.

- Built-in temperature probe for simultaneous measurement of two parameters

- Maintenance-free gel electrolyte

- 1, 2 or 3-point calibration possible
