-Multi-functional suitcase makes carrying more convenient

-It uses big screen Chinese LCD display, and digestion, measuring display become integrated

-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 use national standard samples to calculate and store curve

-The instrument can use national standard samples to calculate and store curve-print the current data and all saved historical data

-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

-USB interface can connect the computer making online operation (optional)
