Testo 206-pH3 Digital pH Meter | pH/Temperature Measuring Instrument with BNC Connection | 0–14 pH

Product Overview

The Testo 206-pH3 Digital pH Meter is a versatile professional pH measuring instrument designed for flexible use across liquid, semi-solid and more demanding media. Unlike dedicated pH meters with a fixed probe, the testo 206-pH3 features a BNC interface that allows an external pH probe to be connected, making it possible to select the appropriate electrode according to the application.

With a 0 to 14 pH measuring range, ±0.02 pH accuracy and 0.01 pH resolution, the instrument is suitable for reliable pH testing in laboratories, food processing, cosmetics, sanitary applications, HVAC and industrial environments.

When a compatible Testo pH probe with an integrated temperature sensor is connected, the instrument can automatically evaluate the temperature. With probes without a temperature sensor, temperature can be entered manually.

The compact one-hand design, automatic final-value recognition and robust TopSafe IP68 protective case make the testo 206-pH3 particularly suitable for routine field measurements as well as demanding working environments.

Technical Specifications

The above specifications are from Testo's current product information; temperature measurement depends on the external probe selected.

External BNC Probe Connection

The major advantage of the testo 206-pH3 is its BNC interface.

The BNC connection allows the user to select a suitable external pH electrode according to the material being measured. This makes the instrument more versatile than dedicated pH meters designed around one fixed probe.

Depending on the application, compatible electrodes can be selected for:

• General liquid measurements

• Food products

• Semi-solid materials

• Laboratory applications

• Industrial liquids

• More demanding media

• Applications requiring temperature measurement

This modular approach allows the same measuring instrument to be adapted to different measurement requirements.

Compatible Probe Options

Testo provides a range of probes that can be used with the testo 206-pH3.

pH Universal Plastic Electrode – 0650 2063

A robust plastic pH electrode without an integrated temperature sensor. It features a maintenance-free gel electrolyte and a single-pore diaphragm designed to reduce clogging.

pH range: 0 to +14 pH
Probe shaft length: 120 mm
Tip diameter: 4 mm
BNC connection: Yes
Cable: 1,200 mm

This probe is suitable for general-purpose pH measurement.

pH Universal Plastic Electrode with Temperature Sensor – 0650 2064

Accurate pH Measurement

The testo 206-pH3 provides a 0 to 14 pH measuring range, making it suitable for measurements across acidic, neutral and alkaline materials.

With:

• ±0.02 pH accuracy

• 0.01 pH resolution

the instrument provides precise readings for routine quality control and process monitoring.

Temperature Measurement

The testo 206-pH3 can also measure temperature when a suitable external pH probe with an integrated temperature sensor is connected.

The specified temperature measuring range is 0 to +80 °C, depending on the pH probe used.

Temperature can be evaluated automatically when the connected probe contains a temperature sensor. If a probe without a temperature sensor is used, temperature can be entered manually.

Automatic Final-Value Recognition

The instrument includes automatic final-value recognition, which identifies when the measurement has reached a stable reading.

This makes routine testing easier because the operator does not need to continuously monitor the displayed value while waiting for the reading to stabilize.

Calibration

The testo 206-pH3 supports 1-, 2- and 3-point calibration, allowing the instrument to be calibrated according to the requirements of the application.

Testo offers compatible pH buffer solutions such as:

• pH 4.01 buffer solution

• pH 7.00 buffer solution

Regular calibration helps maintain measurement accuracy and reliability.

TopSafe IP68 Protection

The testo 206-pH3 is supplied with a TopSafe protective case that provides IP68 protection.

The rugged protective design makes the instrument suitable for:

• Field measurements

• Outdoor use

• Industrial environments

• Food-processing environments

• Laboratory work

• Cleaning-intensive applications

The TopSafe case protects the measuring instrument from water and dirt during normal professional use.

Compact One-Hand Design

The testo 206-pH3 is designed for convenient one-hand operation.

Its compact body measures approximately 197 × 33 × 20 mm and weighs only 69 g, making it easy to carry between different measurement locations.

The two-line LCD provides a clear display of measurement information.

Standard Product Configuration

The Testo India product page identifies the testo 206-pH3, Product No. 0563 2063, as the pH measuring instrument with BNC interface, TopSafe and belt/wall bracket.

Important Note

The external pH probe is selected separately according to the application.

This is important when listing the product on Rinstrument because the 0563 2063 instrument itself should not be advertised as including a specific measuring electrode unless your supplied package specifically includes one. Testo's current documentation lists multiple compatible probes separately.
