Each photometer is delivered in a cardboard box and is supplied with:
Sample cuvette (2 pcs.)
Sample cuvette cap (2 pcs.)
Plastic stopper (2 pcs.)
1.5V AA Alkaline batteries
Instrument quality certificate
Instruction manual
The optical system is sealed from outside dust, dirt and water. The meter uses an exclusive positive-locking system to ensure that the cuvettes are placed into the holder in the same position every time.
With the CAL Check functionality, users are able to validate the performance of the instrument at any time and apply a user calibration (if necessary). Hanna Instruments CAL Check cuvettes are made with NIST traceable standards.
The built-in tutorial mode guides users step-by-step through the measurement process. It includes all steps required for sample preparation, the required reagents and quantities.
The HI-97752 meter measures two important parameters in:
drinking water
surface water
ground water
wastewater
swimming pools
Calcium is a vital plant nutrient and helps to strengthen plant cell walls protecting against heat stress. The method for calcium is an adaptation of the Oxalate Method.
Magnesium is an essential nutrient and helps build a strong immune system. The method for magnesium is an adaptation of the Calmagite Method.
The HI-97752 photometer is a compact and versatile meter suitable for field or bench measurements, featuring a:
Sophisticated optical system
Meter validation using certified CAL Check cuvettes
Tutorial mode guides the user step-by-step
Auto logging
Waterproof IP67, floating case
GLP features
About Calcium and Magnesium
Calcium and magnesium both play important roles in the growth of plants. Calcium helps plant roots develop and increases the resistance and strength of plant tissues and stems. Magnesium is an indispensable mineral that helps in the production of chlorophyll, the light-absorbing green pigment that serves as an energy source for plants. It also increases vitamin concentrations and aids in uptake of phosphorus within the plant body.
