Máy đo Kali Hanna HI97750 (0.0 to 100 mg/L)

Potassium Portable Photometer - HI97750

The HI97750 Potassium Portable Photometer combines accuracy and ease of use in an ergonomic, portable design. Using the HI93750-0 ready made reagents a user can accurately determine the potassium concentration in samples within a low and medium range. The low range measures from 0.0 to 10.0 mg/L potassium; the medium range measures from 10 to 100 mg/L potassium. Users can simply choose the appropriate range depending on their expected sample concentration. The HI97750 offers many advanced features including the exclusive CAL Check^™ function used for performance verification and calibration of the meter.
