Product Description Product Description HM-930 ultraviolet spectrophotometer is a special ultraviolet spectrophotometer used to measure oil in water. The instrument is an efficient, environmentally friendly, accurate and fast oil measuring instrument developed according to the requirements of national environmental monitoring technical specifications. The product is simple to operate, has good precision, high sensitivity and stable performance, and can meet the application requirements of customers. The instrument should be widely applied to environmental monitoring stations at all levels of the environmental Protection Bureau, water conservancy and hydrological monitoring stations, Marine environmental monitoring, water supply companies, agriculture, animal husbandry and fishery water quality testing, third-party environmental testing companies and many other fields. It is suitable for the determination of oil in surface water, groundwater and seawater. Water samples were extracted with n-hexane at PH≤2 to determine oil. The extraction liquid was dehydrated with anhydrous sodium sulfate and then adsorbed by magnesium silicate to remove polar substances such as animal and plant oils. The absorbance was determined at 225nm wavelength. The oil content and absorbance values were in accordance with Lambert-Beer law. Product Parameters 1. 7-inch LCD screen, easy to operate, with printing function, no need to upload PC side operation; 2. Using ultraviolet light for detection, the instrument automatically measures the absorbance, sets the measurement parameters according to the current national standard, and can directly read the measurement results of oil in water without manual conversion; 3. Adopt advanced and reasonable optical path system design, high-quality optical components and low noise circuit design, optical path debugging structure, optical system for double beam proportional monitoring, the instrument has the power on self-test function, can correct the instrument system and possible fault judgment; 4. With n-hexane transmittance detection function: using water as a reference, using 2cm quartz colorimetric dish to determine n-hexane at 225nm, the analysis software automatically gives the purity of n-hexane reagent qualified or unqualified judgment; 5. In addition to being used as a special ultraviolet oil detector, the software is easier to operate, more flexible, and has a strong range of application; Technical parameter StandardNational Environmental Protection standard "HJ970-2018 Determination of petroleum in Water quality by ultraviolet spectrophotometry (Trial)";Method detection limitWhen the water sample volume was 500ml and the extraction liquid volume was 25ml, a quartz cuvette of 2cm was used, and the detection limit was 0.01mg/L.

After working for a long time, the following parts may fail or fail. Please go to the designated repair point for maintenance or ask the user to repair under the guidance of professional personnel. 1.1 Filter After a period of use, the transmittance of the filter will decrease. When the instrument can not work normally, the instrument will automatically give a display to remind the user to replace it in time. The replacement method is as follows: open the upper cover of the instrument, find the filter disc, find the failed filter, take out the old film that has failed, and replace it with a new film of the same specification. 1.2 Light Source When the light source lamp is damaged, the instrument will automatically give the display, then you can open the cover of the instrument, after inspection to determine the lamp is damaged, unplug the lamp socket, gently remove the lamp from the bottom up with the hand, replace the new lamp of the same specification. If the instrument still indicates fault after replacing the new bulb, please inform the professional staff of the division to debug in time. Packaging & Shipping
