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.
