Testo 206-pH1 pH Meter, ±0.02pH Accuracy, 0.01pH Resolution, 14pH Max, +60 °C Max

For semi-solid media and liquid measurements, Testo presents the 206 series for fast pH testing.

Stand out features include a large volume of gel electrolyte and dual wall diaphragm, leak-proof probe which is maintenance-free and insensitive to dirt. The protective cover is dish-washer safe, hygienic and protects the measuring instrument from water, dirt and impact.

• Auto final value recognition
• Dual display
• 1, 2, or 3-point calibration possible
• Gel electrolyte
• Built-in temperature sensor
• 0 to 14 pH measuring ranger
• 0.01 pH resolution
• Protection class IP68

From laboratories and quality control to schools, pH meters have a wide range of application. They are often used in solutions to indicate alkalinity or acidity, some also measure electrical potential, these are called "potentiometric pH meters". Usually with a meter and a probe, some pH meters also measure temperature. Whatever type of measurement is needed RS offers a wide range of pH meters to meet your pH measurement needs.

Measure the acidity of a range of liquids and semi-solids using this pH meter from Testo. In addition to the pH electrode immersion probe, the device contains an NTC (negative temperature coefficient) probe that compensates for temperature to ensure a higher degree of accuracy. The electrolyte gel and dual-wall diaphragm ensure the probe is reliably leakproof and able to withstand immersion in foods and soil without damage.

• Robust battery life of 80 hours for long-lasting use in the field
• Temperature accuracy of ±0.4°C and pH accuracy of ±0.02 for precise readings
• Wide operating temperature range of 0°C to +60°C means it's suitable for use with cold or hot liquids
• Light weight of 69g for portability and ease of handling

• Laboratory experimentation
• Food industry quality control
• Municipal water supplies
• Brewing industry

The meter's IP68 (ingress protection) rating means it can withstand exposure to dust and submersion in water to a maximum depth of 1.5m for up to thirty minutes. This makes it a good choice for use in demanding industrial settings.

pH & Water Analysis - pH & Temperature Meters Testo 200 Series

Instead of a liquid electrolyte, these probes use a gel as a reference substance for pH measurement. This facilitates the use of a hole diaphragm between the measurement electrode and housing in place of the micro-porous structure usually used in pH probes.They are almost completely maintenance-free, robust and unaffected by dirt and dust.,Gelcap,A potassium chloride solution is usually used to store pH probes which, as with every liquid, can leak. To prevent this the potassium chloride solution is available in a gel filled probe/meter cap that does not drip or leak.
