Profile
The TP-301E instrument adopts ergonomic design, imported tungsten light source and excellent optical structure. The optical performance is stable and the detection effect is accurate. There are 19 kinds of test parameters such as COD, total phosphorus and total nitrogen. At the same time, it has powerful scientific research procedures such as wavelength scanning, photometric measurement and curve fitting. It is equipped with large-screen color LCD screen for direct reading. The measurement results are straightforward and can be widely used in water quality testing in industrial, municipal, environmental protection and education fields.
Principle
TP-301E multi-parameter water quality analyzer, the principle of routine detection (COD / total phosphorus / total nitrogen / turbidity / suspended matter), the determination of COD using digestion tube closed catalytic digestion colorimetry, the determination of total phosphorus using closed digestion Colorimetric method, the determination of total nitrogen using alkaline persulfate digestion photometric method, are all US EPA approved methods. After the data is processed by the imported tungsten light source and the microcomputer, the COD, total phosphorus and total nitrogen values of the sample are directly displayed, and the unit is displayed in units of mg/L.
Features
1. It adopts ergonomic design, ABS material case, anti-oxidation, acid and alkali resistance.
2, built-in water quality analysis, wavelength scanning, photometric measurement, curve fitting and other detection functions to meet the needs of scientific research and daily testing.
3, large-screen color LCD screen, user-friendly operation interface, direct reading of concentration.
4, the instrument uses a multi-function colorimetric pool, can be used to digest colorimetric tube (Φ16mm) colorimetric, can also be used in multi-standard cuvettes.
5, with data storage, query, print function.
6, the instrument is equipped with a full set of operating procedures and instructions
7, equipped with pipettes and special reagent supplies, the operation is simpler and safer.
8, using an integrated button, the button is not easy to damage, the operation is more sensitive.
