1 Method basis: resorcinol spectrophotometry
2 Measurement range: (0~100.0)mg/L
3 Accuracy:when ≤2.0mg/L,≤±0.2mg/L;when>2.0mg/L,≤±10%
5 Measurement period: The minimum measurement period is 50 minutes (depending on the length of the digestion time). According to the actual water sample, the digestion time can be arbitrarily modified at (10 ~ 45) min
6 Sampling period: The time interval (1~999min) can be adjusted arbitrarily and the whole point is Selected
7 Calibration cycle: manual calibration or set cycle for automatic calibration.
8 Maintenance period: usually once a month, about 30 minutes each time.
9 Environmental requirements: indoor temperature adjustable, recommended temperature (5 ~28)ºC; humidity ≤ 90% (no condensation).
12 Other: Abnormal alarm and power failure will not lose data;
Touch screen display and command input
After abnormal reset and call after power failure, the instrument automatically discharges residual reactants in the instrument and automatically resumes working condition.
