Hanna Instruments HI9811-5 Portable pH/EC/TDS/Temperature Meter
A single probe in the affordable, waterproof HI9811-5 portable meter simultaneously measures pH, conductivity (EC), total dissolved solids (TDS), and temperature (°C).
With specific buttons for measurement modes to be presented on the LCD and knobs for single point pH and EC/TDS calibration, the meter’s operation is made simpler. The HI9811-5 is best suited for applications in agriculture, greenhouses, and hydroponics.
- 3 in 1 probe with pH, EC/TDS and temperature sensors
- Amplified pH electrode for immunity to electrical noise including from ballasts and pumps
- Large LCD with instructions
