Thunder Magnetic DGB-401 multi-parameter Water Quality Analyzer is a special detection instrument used to detect chemical oxygen demand, ammonia nitrogen concentration, total phosphorus concentration value, using the principle of photoelectric colorimetric method for measurement, mainly used in the field of environmental protection to detect water quality, using the integration of 4 wavelengths of LED light source for measurement, high measurement accuracy.DGB-401 multi-parameter Water Quality Analyzer is divided into two ranges of high concentration and low concentration, which can be selected for different needs, and the analyzer shell has IP65 protection level, which is dustproof and waterproof.
a)DGB-401 multi-parameter Water Quality AnalyzerThe LED light source used integrates four wavelengths: 420nm, 470nm, 620nm and 700nm, and the analyzer is small in size and has high measurement accuracy.
b) Good human-machine interface, with absorbance value and concentration value displayed at the same interface; The LCD contrast is adjustable;
c) Two measurement modes are available, balance measurement and continuous measurement, to meet different usage needs;
d) The measurement is in accordance with the GLP specification, and 200 user operator numbers can be set, the viewing range can be set according to the absorbance/concentration value, the data can be deleted according to the current data/current display data/all data, 200 sets of measurement data can be stored at different wavelengths, and the data can be printed out.
e) Up to 20 calibration points can be calibrated, and users can create their own standard curves; Support users to edit the calibration results, optimize the calibration curve, and avoid repetitive work (users can manually modify the curve by themselves, including inserting data points, deleting data points, modifying the current concentration value, modifying the current absorbance value, etc.; )
f)DGB-401 multi-parameter Water Quality AnalyzerIt has the functions of automatic shutdown (in min) and power-off protection;
g) It has the function of automatic control of backlight time (in S) to prolong the battery life;
h) The shell has IP65 rating, good waterproof and dustproof, and has the design of a portable toolbox;
i) USB communication interface, which can communicate with the computer through the data acquisition software REX V2.0;
j)DGB-401 multi-parameter Water Quality AnalyzerSupport connection with power bank;
k) two data input methods: timer input method and keyboard input method;
l) Support alkaline battery power supply and USB port direct power supply (support to connect to mobile power supply) two power supply modes;
m) Restore default data, work efficiency;
1、DGB-401 multi-parameter Water Quality AnalyzerThere are 4 wavelengths to choose from, and through software upgrades, you can expand multiple environmental protection testing items;
2. The shell has IP65 protection level, standard 6-hole portable digestion, a variety of power supply methods, easy to carry and use;
3. Users can edit the calibration measurement results, optimize the calibration curve, and greatly improve work efficiency;
Chemical Oxygen Demand:potassium dichromate—spectrophotometry;
Ammonia nitrogen: Nessler's reagent—spectrophotometry;
Total phosphorus: ammonium molybdate—Spectrophotometry.
