Tough environments require a robust and durable device, the HI 9811-5 is just that. Not only is this instrument water resistant but it also compensates for temperature changes with a built-in temperature sensor, meaning it's accurate in even more environments.

The specially engineered meter and probe features a gel electrolyte and fibre junction, giving a fast response time. Easily switch between conductivity, TDS and pH without the need for a probe change, reducing the number of instruments used and time between measurements. Calibration is also made quick and easy with the dials located on the front panel of the meter.

• On-screen user guides
• Battery % display
• Fast response times
• Auto temperature compensation
• Touch button parameter switching
• Water resistant

Replacement probe available HI 1285-5 (724-3683)

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.
