ST-1B water quality detector (4 items)

Introduction:

ST-1B water quality detector (4 items) use for detecting chromaticity,chloride,sulfate and Ozone of water quality

Features;

* The standard curve is built in, with the special reagent directly to carry out quantitative detection.

* The results showed that the concentration, the absorbance and the transmittance.

* Imported super bright light emitting diode light source and detector.

* Advanced light source drive and calibration technology. After the instrument is started, the light source is automatically calibrated to the optimum state, which ensures the stability, precision and a wider measurement range of the instrument.
