M300S near red moisture meter
The principle of infrared light absorption The molecular structure inside a substance, such as the oxygen-hydrogen bond in water and the carbon-hydrogen bond in organic matter, will absorb near-infrared light of a specific wavelength. At a specific wavelength, the reflected near-infrared energy is inversely proportional to the number of molecules it contains that absorb near-infrared rays. The moisture meter analyzes the change of near infrared energy at a specific wavelength based on the principle that near infrared wavelengths are absorbed by water molecules. The company also specializes in the production and sales of non-woven moisture meters , sintered moisture meters and other products
The near-infrared moisture meter collects near-infrared beams of multiple wavelengths on the surface of the object to be measured, and the near-infrared beams reflected on the surface are received and processed by an infrared optical detection system. This infrared optical detection system can quickly process data. An embedded ultra-performance miniature digital signal processing chip is used to process, store and display the required data, and its accuracy and stability are outstanding.
The composition of the M-300S near-infrared moisture meter: The M-300S is an online moisture analyzer with a 304 stainless steel case added to the M-300S. It meets the sanitation permit requirements of the food industry and has the characteristics of anti-corrosion. The instrument adopts a dual-core design, and the main components are two parts, a near-infrared probe and a display.
Near-infrared probe: Imported light-guided PBS detector is used. The detector is packaged independently. The external light does not interfere with the reference measurement; the reference measurement light of the optical path structure and the product measurement light use the same optical path to eliminate the influence of detection errors. The probe has a built-in single-chip microcomputer for signal analog-to-digital conversion, which avoids the problem that the optical signal is easily interfered by the analog signal transmission. The probe uses DC24V power supply and low voltage is safer. These can improve the measurement accuracy and stability of the near infrared moisture meter.
The display adopts an industrial touch screen, which can switch between Chinese and English display, with graphical curve display, up to 6 months of history, and the USB interface supports data export and software upgrade functions. The host also has analog quantity (DC4-20MA), digital output (MODBUS-RTU, MODBUS-TCP), and digital signal (two passive contacts). The signal output is more flexible and convenient,
The M-300 online near-infrared moisture meter is mainly used in industries with high-end requirements, such as steel ore, food and other industries. The M-300 probe signal is transmitted using a digital protocol. The distance between the probe and the human-machine interface can be up to 50 meters. , It is suitable for the working condition where the measured moisture point and the distance between workshops are far.
