(5~50) ℃ (manual or automatic)

B1 calibration solution -2.00 × 10-2 mmol/L

B2 calibration solution -2.00 × 10-1 mmol/L

B3 calibration solution -2.00 mmol/L

(B3 calibration solution is also used as an immersion solution for activating electrodes)

(a) B1/B2 calibration - using B1 and B2 calibration solutions for calibration, suitable for low concentration water quality<2.00 × 10-2 mmol/L, such as boiler water.

(b) B2/B3 calibration - using B2 and B3 calibration solutions for calibration, suitable for general water quality.
