This manual provides you with the necessary information for the correct use of the instrument.
The HI 96751C is an auto-diagnostic portable microprocessor meter designed for measuring sulfate content in water samples within a range of 0 to 150 mg/L. It features an advanced optical system based on a Light Emitting Diode (LED) and a narrow band interference filter to ensure accurate and repeatable readings. The instrument includes a CAL CHECK validation function to verify performance using NIST traceable standards.

The meter measures sulfate content in water samples in the 0 to 150 mg/L (ppm) range.
Sulfate is precipitated with barium chloride crystals, and the light absorbance of the suspension is measured.
A 'Battery low' message appears indicating the battery must be replaced soon, and a 'Dead battery' message locks the meter if the battery is depleted.
