Welcome: U-THERM INTERNATIONAL (H.K.) LIMITED
This instrument can quickly determine the COD, ammonia nitrogen, total phosphorus in waste water three indicators, has a print function, fast measurement, simple operation, is the user's three-parameter analyzer preferred products.
Features
-It can accurately test chemical oxygen demand (COD), ammonia nitrogen, total phosphorus (turbidity) indexes in various body of water
-It has memory of 100 curves, 15 standard curves, 85 extensive curves, and they all can be used in different environment, different waste water and other conditions
-As for the digestion of indoor temperature-200℃, the users can adjust by themselves according to requirement, which has more compatibility
-The instrument can be calculated and stored curves according to the standard sample
-The built-in printer can print the current data and check historical data
-USB interface can connect computer to implement online operation and can automatically generate the chart (optional)
-Cold light source, narrow band interference, and the light resource life is 100,000 hours
-Digestion power and load quantity can be adjusted automatically, and it also has intelligent constant temperature control and time delay
-It can adjust and store temperature and time at will
-Rear-mounted spectral technology is domestic initiative, which can avoid external light interference and make the test data more stable and reliable
