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

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

• Laboratory experimentation

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.

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

• Auto final value recognition

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.

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.
