Features
1) Verification regulation: Complies with the Level 2 requirements of the JJG-178 Verification Regulation for Ultraviolet, Visible, and Near Infrared Spectrophotometers;
2) Equipped with a multifunctional single colorimetric cell, compatible with 10mm, 20mm, 30mm colorimetric dishes and φ 16mm tube colorimetric. The upgraded limit function of the single colorimetric cell greatly improves the consistency and accuracy of sample measurement;
3) Easy maintenance: Unique socket type tungsten/deuterium lamp, light replacement without optical debugging, equipment maintenance is more convenient;
4) Professional total nitrogen determination: can be used as a professional total nitrogen analyzer, with automatic switching between UV dual wavelengths, simple and easy to use, flexible and efficient, good wavelength repeatability, precise results, and direct concentration reading;
5) Preset curves: 74 measurement modes and 360 curves are preset, including 277 standard curves and 83 fitted curves;
6) Supporting reagents: well-equipped professional consumables and reagents, greatly reducing work steps and making measurements simpler and more accurate;
7) Accurate measurement: Using imported high-quality holographic gratings to further reduce instrument stray light, making instrument analysis more accurate;
8) Easy to operate: 7-inch color touch screen, user-friendly design, direct reading of concentration, English display interface;
9) Data processing: It can store 12000 sets of data and can be freely viewed. It supports instant printing and can be uploaded to a computer;
10) Supporting digestion instrument: Equipped with a 30 hole dual temperature zone multi parameter digestion instrument, it can simultaneously digest water samples with two different temperature indicators, saving time.
