pH Measurement

The Testo 206-pH1 measures pH values from 0 to 14 pH, covering the majority of common acidic, neutral and alkaline liquid applications.

The 0.01 pH resolution allows users to monitor relatively small changes in acidity or alkalinity.

It can be used for routine checks of:

• Water

• Food products

• Beverages

• Liquid ingredients

• Process liquids

• Laboratory samples

• Cleaning solutions

• Other compatible aqueous liquids

Temperature Measurement

The Testo 206-pH1 incorporates a temperature sensor alongside the pH electrode.

Temperature measurement is important because pH readings can be affected by temperature. The instrument therefore uses the measured temperature for automatic temperature compensation.

The temperature measurement range is approximately 0 to +60 °C, with a resolution of 0.1 °C.

Automatic Temperature Compensation

One of the important advantages of the Testo 206-pH1 is its integrated temperature measurement and automatic compensation.

During measurement, the instrument determines the temperature of the sample and automatically compensates the pH reading accordingly.

This helps users obtain more reliable pH measurements when working with samples at different temperatures.

Robust Combination Electrode

The Testo 206-pH1 uses a dedicated combination pH electrode designed for practical measurement of liquids.

The electrode can be replaced when required, extending the useful service life of the instrument.

The protective cap helps protect the electrode during storage and keeps it in suitable condition between measurements.

Calibration

The Testo 206-pH1 supports professional pH calibration procedures.

Calibration can be performed using standard buffer solutions, allowing the instrument to be adjusted according to the application and measurement requirements.

Regular calibration is recommended when accurate pH measurements are important.

Stable Measurement Recognition

The instrument can recognize when the measured value has stabilized, helping the user determine when the displayed result is ready to be recorded.

This makes routine pH testing faster and easier, particularly when multiple samples need to be checked.

Food & Beverage Applications

The Testo 206-pH1 is particularly useful for checking pH in food and beverage applications.

Potential applications include:

• Food production

• Beverage production

• Dairy products

• Sauces

• Liquid food products

• Process water

• Quality-control checks

pH is an important quality parameter in many food-production processes, and routine measurement can help maintain consistent production conditions.

Water & Liquid Applications

The instrument can also be used for general liquid pH measurements, including:

• Water-quality checks

• Process water

• Wastewater-related checks

• Laboratory water testing

• Cleaning solutions

• Industrial liquids

The suitability of the instrument should be evaluated based on the specific sample characteristics and electrode requirements.

Laboratory Applications

The compact design of the Testo 206-pH1 makes it useful for routine laboratory measurements where portability is important.

It can be used for quick pH checks of compatible liquid samples without requiring a large benchtop pH meter.

Waterproof Design

The Testo 206-pH1 is designed with a high level of protection for demanding measurement environments.

Its IP68-rated construction provides protection against dust and water ingress under the manufacturer's specified conditions.

This makes the instrument particularly convenient for applications where accidental contact with liquids is likely.

Compact & Portable Design

The Testo 206-pH1 is designed as a handheld instrument that can be easily transported between measurement locations.

Its compact construction makes it suitable for:

• Field inspections

• Production floors

• Food-processing areas

• Laboratories

• Water-treatment facilities

• Quality-control departments

Battery & Power

The instrument uses 2 × CR2032 button-cell batteries.

The manufacturer specifies a battery life of approximately 300 hours, depending on operating conditions.

Automatic switch-off helps conserve battery power when the instrument is not being used.

Typical Users

The Testo 206-pH1 is suitable for:

• Laboratory technicians

• Food-processing professionals

• Beverage manufacturers

• Quality-control personnel

• Water-treatment professionals

• Environmental technicians

• Production technicians

• Maintenance teams

• Researchers

• Process-control personnel

Main Applications

Why Choose Testo 206-pH1?

The Testo 206-pH1 combines pH measurement and temperature measurement in one compact instrument.

Its automatic temperature compensation, replaceable electrode, calibration capability, protective cap and robust construction make it a practical choice for professionals who need reliable pH measurements directly at the sampling location.

It is particularly useful where portability and quick measurements are more important than the larger footprint of a laboratory benchtop pH meter.
