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.

Use this Testo pH probe to determine the chemical conditions of substances. It's suitable for use with semi-solid and liquid media for versatility. A large volume of gel electrolyte and a dual-wall diaphragm make the unit leak-proof and dirt-resistant for maintenance-free use. The tough ABS housing is dishwasher-safe for use in hygienic applications. This material also protects the instrument against impact and wear for durability in harsh environments.

• Wide operating temperature range of 0°C to +60°C for use in demanding conditions
• Compact probe shaft diameter of 15mm to fit easily into tight spaces

• Laboratories
• Quality control processes
• Swimming pools
• Soil measurements
• Breweries

This pH probe has a high accuracy of +0.02pH to ensure you get precise results.

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.
