Hanna HI991301 | Portable Waterproof pH/EC/TDS High Range Meter

The Hanna HI991301 is a high-range portable waterproof meter for users who need to measure pH, conductivity, TDS, and temperature in more concentrated water samples. It is suitable for applications where EC and TDS levels exceed the limits of low-range meters.

This model is useful for hydroponic nutrient solutions, greenhouse water, brackish water, cooling towers, process water, and industrial utility checks. The dedicated HI12883 probe measures pH, EC/TDS, and temperature, reducing equipment handling during field testing.

For customers in Pakistan, the HI991301 is a strong option for agriculture users, water treatment contractors, chemical plants, cooling tower operators, and industrial maintenance teams. Its IP67 waterproof body, large three-line LCD, calibration status display, and quick-connect probe system make it a dependable instrument for professional field work.
