EFC-F economical COD speed measuring instrument Introduction
EFC-F economical COD speed measuring instrument is developed and improved according to the latest national standard "Fast digestion spectrophotometry (HJ924-2017)", which is suitable for many testing standards at home and abroad. It is fast, efficient, accurate, intuitive, direct reading, and microcomputer control technology. It is widely used in the determination of chemical oxygen demand (COD) in surface water, groundwater, domestic sewage and industrial wastewater. The application of cold light source technology makes the life of light source lamps up to 100,000 hours. The instrument has the advantages of high detection accuracy, wide detection range and powerful functions, and is an ideal choice for water quality analysis.
Feature
(1) Rapid, efficient and accurate detection of the concentration of chemical oxygen demand (COD) in water.
(2) A practical instrument that is improved, upgraded and developed according to the latest national standard “Fast Dissolution Spectrophotometry (HJ924-2017)”. The high and low ranges are measured with different wavelengths, which makes the high and low range measurement accuracy higher.
(3) It adopts imported high-brightness and long-life cold light source, and the life of the light source is up to 100,000 hours.
(4) Direct reading of concentration, large-screen LCD Chinese display, user-friendly operation interface, simple and time-saving operation.
(5) Digestion and detection The same digestion colorimetric tube is used, and the operation is simpler.
(6) 100 standard curves and 5000 measured values (date, time, parameters, test data) can be saved.
(7) Memory standard working curve, the user can also calibrate the curve as needed.
(8) The operation interface is more user-friendly, with the standard curve missing and factory reset function.
(9) It has data power-off protection function and data storage function, so that the measurement record can be queried at any time.
(10) The outer casing is made of sheet metal, which is beautiful and durable.
(11) The analyzer and the digestion device are separated to avoid the influence of the high temperature portion on the optical system.
(12) The digestion instrument is used for the digestion of COD, total phosphorus, total nitrogen and other items; intelligent PID temperature control technology, uniform heating and fast heating.
(13) Automatic temperature control of the digestion instrument, anti-over temperature protection system, display current temperature, set temperature, time.
(14) Digestion temperature: adjustable from room temperature to 200 °C, and better compatibility.
(15) The protective cover is made of fully transparent heat-resistant material, which can directly observe the state of the water sample and ensure the safety and reliability of digestion.
(16) The setting time of the digestion device can be adjusted freely within the range of 0-999 minutes, and the function is more powerful.
(17) has a USB interface to transfer current data and all stored history data to the computer.
