HI-97752 Calcium and magnesium photometer: Range: 0 to 400 mg/L, Mg: 0 to 150 mg/L information
Hanna's extended description
Each photometer is delivered in a cardboard box and is supplied with:
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:
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:
