Water Quality Analyzer

We are offering water quality analyzer.
Summary:
water quality analyzer is designed specially for testing water quality in laboratory or outdoors. It not only can meet the accuracy requirement of laboratory but also has the advantage of portability to carry on quick and emergent testing at site.
Key features:
· very easy to use, without drawing standard curve
· high testing speed, results displayed automatically
· calibration-factory setting and 5 user programmable methods
· connects to different types of printers and pc
· results are displayed in concentration, absorbance or percent transmittance
· wavelength- automatic select ion and calibration
· portable, dustproof, waterproof, fireproof and chemical resistance
· data logger-automatic data storage of at least 99 analysis results
· conforms to cj3020-93, gbt14848-93, cjt206-2005, gb3838-2002,
· gb11607-89
principle:
the light from led lamp source penetrates the sample cell, and is caught by the detector. After magnetization, disposal, modulus change, calculate ion and analyses, display the final result controlled by the mpu. The sample gets chemical colorific react ions with some special reagent, and then the mixture can absorb visible light at some wavelength obviously. The absorption intensity have direct ratio with the concentration of the sample. We detect the signal change between the two results before and after the sample cell, and then get the sample concentration by calculate ion.
