Infrared Oil Meter
This instrument is mainly used to measure the oil content in surface water, groundwater, and industrial wastewater. It can also be used to monitor oil in flue gas and solids in the catering industry. This instrument is a professional instrument for measuring the oil content in water, gas, and solids.
Instrument Features:
◆The instrument comes with an embedded 10.8-inch win10 system tablet computer with full HD display;
◇Built-in professional oil measurement software, the software spectrum is clear and can distinguish various interference phenomena;
◆The software has functions such as infrared spectrum analysis, spectrum storage, data query, statistical calculation, and printing;
◇Opto-mechanical and electrical integration design and electrically modulated light source improve instrument reliability;
◆High accuracy: the error of each measurement does not exceed ±1.5%;
◇Baseline drift is less than 0.005AU/60min;
◆Has the function of direct reading of non-dispersion measurement results without conversion;
Fundamental:
According to the national standards GB16488-1996 and HJ637-2018, use tetrachlorethylene to extract oil substances in water, then use anhydrous sodium sulfate to isolate impurities and moisture, separate the solution of oil and tetrachlorethylene, and measure the total oil content of the extract.
