The whole machine adopts a mold design, with a trendy and fashionable appearance; The application of keyboard based operation technology has achieved the practical intelligence of the instrument, which has the characteristics of acid and alkali resistance, corrosion resistance, etc.
It can be widely used in scientific research institutes, sewage engineering, water environment testing, petrochemicals, metallurgy and steel, biomedicine, food and dairy industry, wool textile printing and dyeing, electronic machinery, municipal water conservancy, aquaculture, photovoltaics, leather, papermaking, electroplating and other industries.
Intelligent digestion device, test tube rack, water cooling rack, solid reagent, reaction tube, colorimetric dish rack, semi-automatic liquid dispenser, etc
[Functional Features]
❖Accurately measure the chemical oxygen demand (COD), ammonia nitrogen, and total phosphorus (turbidity) indicators in various water bodies
❖Simultaneously supporting two colorimetric methods: colorimetric dish and colorimetric tube
❖100 curves in memory, 15 standard curves, and 85 extended curves can be freely applied in different environments, wastewater, and other conditions
❖The temperature is set between room temperature and 200 ℃, and users can adjust it according to their needs, making it more compatible
❖The instrument can calculate the storage curve based on standard samples
❖Built in printer, capable of printing current data and querying historical data
❖USB interface, connected to the upper computer for operation, can automatically generate charts (optional)
❖Cold light source, narrowband interference, light source lifespan up to 100000 hours
❖The digestion power is automatically adjusted according to the number of loads, with intelligent constant temperature control and delay protection
❖Temperature and time can be adjusted and saved freely
❖Rear mounted spectroscopic technology avoids external light interference and ensures more stable and reliable test data
