SIA-3000 series is a new generation mini-water quality online analyzer with high integration, easy operation, and high accuracy; it is suitable for micro water stations and mobile water stations. This system is a series online facility for chemical oxygen demand(COD), total nitrogen(TN), total phosphate (TP), ammonia, and heavy metals.

Product features
  • Due to its excellent anti-interference capabilities, its’ dual-beam design efficiently limits the impact of factors such as chromaticity and turbidity of the water body that may impair measurement results. 
  • With a reagent and waste liquid volume that is 80% less than similar products, SIA-3000 has lower operation and maintenance costs.
  • Continuous measurement, periodic measurement, manual measurement, remote control measurement mode available.
  • Capable of performing automatic calibrations at any time, with 1-240h regular intervals.
  • Capable of performing multi-point calibration for linear, quadratic and cubic fitting.
  • Capable of performing automatic cleaning cycles based on the complexity of the on-site water sample.
  • It detects reagents and water samples, determines whether there is a shortage of liquid, generates a warning alarm, and has functions such as reagent residual warning, instrument log, and fault alarm systems.
