Product features:
◆High range measurement of low concentration: using ring sampling to reducedilution times and improve repeatability. The new acceptance standard requiresthe instrument range to be 2-3 times the emission standard, but the actualconcentration of the discharged water sample is very low. In response to thissituation of measuring low concentration with a high range, the advantages areparticularly obvious
◆Innovative measurement method (patent) (1) with anti turbidity interferenceautomatic compensation function, which will not make measurement errors whencollecting turbid water samples; (2) with bubble elimination function, whichhas a significant effect on wastewater with bubbles, such as photovoltaicplants, printing and dyeing plants, etc
◆ Automatic range switching function: Choose any combination of low range andhigh range, and the instrument will automatically switch to the optimal rangebased on the actual water sample concentration
◆ Multiple quality control functions: zero point/span/standard sampleverification, blank testing, reserved parallel sample and spiked recoveryinterface
◆Multiple measurement modes, key parameter display, operation, verification,calibration logs, upper and lower limit warning
◆ Power on self-test, automatic reset, liquid shortage alarm, power-offprotection, waste liquid separation
◆ Supports 2-channel RS232/485, 2-channel 4-20mA communication interfaces, andreal-time data printing for printers
◆ (Optional) Cloud monitoring function: Real time monitoring of instrument statuson mobile phones, remote alarm, remote fault diagnosis
◆ (Optional) Reagent Refrigeration: Equipped with a reagent refrigeration boxto extend the reagent warranty period
