The HI 96752 Calcium and Magnesium High Range ISM is a portable ion-selective conductivity meter for measuring calcium and magnesium in water. The instrument employs advanced microprocessor technology and a full automatic ion-selective electrode to provide fast, accurate, and reliable measurement results.
The Hanna Instruments HI96752 is a high-range ISM (Indicating Spectrophotometric) instrument designed to measure Calcium and Magnesium concentrations. It utilizes the Orolate method for Calcium and the Calmogite method for Magnesium, featuring an LED light source and a silicon photocell detector with a narrow band interference filter at 466 nm.

The instrument uses the Orolate method adaptation for Calcium and the Calmogite method adaptation for Magnesium.
For Calcium, accuracy is +/- 10% of reading; for Magnesium, it is +/- 3 mg/l or +/- 3% of reading.
A 'Battery low' warning appears, indicating the battery must be replaced soon. If dead, normal operation is interrupted.
No, you should not validate or calibrate with other standards as it will result in erroneous readings.
