Product information "HI96719 Mg Hardness, Standard Method, Portable Photometer"
Certified calibration and verification standards
BEPS (Battery Error Prevention System)
The HI 96719 measures the magnesium hardness content, as CaCO3, in water and wastewater in the 0.00 to 2.00 mg/L (ppm) range.
This meter uses an exclusive positive-locking system to ensure that the cuvette is in the same position every time it is placed into the measurement cell. It is designed to fit cuvettes with a larger neck making it easier to add both sample and reagents. The cuvettes are made from special optical glass to obtain best results.
HI 96719 is supplied with sample cuvettes with caps (2), 9V battery and instruction manual.
