Welcome: U-THERM INTERNATIONAL (H.K.) LIMITED
The whole machine adopts the integrated mold design, the appearance of fashion; application of the latest keyboard-type operating technology, the realization of the instrument features of practical intelligence, with acid and alkali resistance, corrosion resistance and other characteristics; also supports colorimetric and colorimetric tube two color comparison the way.
Features
-Accurately determine chemical oxygen demand (COD), ammonia nitrogen, total phosphorus (turbidity) indicators in various water bodies
-At the same time support colorimetric and colorimetric tube two colorimetric methods
-Memory 100 curves, 15 standard curves, 85 expansion curves can be freely applied under different conditions, different waste water and other conditions
-Temperature setting room temperature ~ 200 °C, the user can adjust according to need, more compatible
-The instrument can calculate the storage curve according to the standard sample
-Built-in printer, can print current data, query historical data
-USB interface, connect the computer to the host operation, automatically generate a chart (optional)
-Cold light source, narrow band interference, light source lifetime up to 100,000 hours
-Digestion power automatically adjusts with the load quantity, intelligent constant temperature control, delay protection
-Temperature and time can be adjusted and saved
-First domestic rear-mounted splitter technology to avoid external light interference and test data is more stable and reliable
