ZH-800 Infrared Spectrophotometer is mainly used in the measurement of oil content in surface water, groundwater and industrial wastewater. This instrument is a professional instrument for measuring oil content in water, gas and solid.

High accuracy: the error of each measurement does not exceed ±2% (40㎎/L)

Baseline drift is less than 0.005AU/60min

Electrically modulated light source to improve instrument reliability

Automatic zero adjustment, automatic adjustment of instrument full scale value

The instrument uses RS232 or USB2.0 interface, which is convenient to connect with computer

With mathematical statistics, spectrum display, storage, printing and other functions

With the function of measuring instrument correction factor

Direct reading of non-dispersive measurement results without conversion

Can test the purity of carbon tetrachloride

Other non-carbon-chlorine organic solvents such as S-316, carbon tetrachloride, tetrachloroethylene, trichlorotrifluoroethane can be used as extractants

It can be extended to field-type infrared spectrophotometer, which can be driven by 220V AC power supply or external DC power supply (it can be charged for 8 hours). After expansion, it can be applied to the measurement of oil concentration in water in the field or emergency accident site, and can also perform accurate qualitative and quantitative analysis of oil samples in laboratories using AC power.
