Hanna Instruments HI991300 Portable Waterproof pH/EC/TDS Meter (Low Range)
With a single amplified probe, the HI991300 is a compact, lightweight, and water-resistant portable meter that measures pH, conductivity (EC), total dissolved solids (TDS), and temperature.
Two buttons simplify the meter’s functioning. The first is used for calibration and on/off, while the second is utilized to change between measurement modes. Advanced features on the HI991300 include a configurable EC to TDS conversion factor (0.45 – 450 ppm and 1.0 – 1000 ppm).
- 3 in 1 amplified probe with pH, EC/TDS and temperature sensors
- Quick Cal Mode to calibrate pH and EC/TDS with one solution
- EC to TDS Conversion factor selectable between 0.45 and 1.0
