BGT-PM2512 Detecting the concentration of particulate matter with diameter less than 2.5 microns and less than 10 microns in theair.The principle of laser scattering is adopted, that is, the laser is irradiated on the suspended particulate matter in the air to generate scattering, and the scattered light is received by the detector at a certain Angle,and the generated photocurrent is amplified to obtain a corresponding curve of the electrical signal and the particulate matter.After data collection by microprocessor, the particle mass with different particle size per unit volume is obtained through a series of algorithms.This product is an industrial standard output (RS485) PM monitor, mainly used in environmental protection, scenic areas, parks and other fields. It detects changes in dust concentration trends, enables long-distance transmission, and can be connected to various standard secondary instruments. Monitor air temperature and humidity.

The Multi-Plate Radiation Shield protects temperature,relative humidity or barometric pressure sensors from error-producing solar radiation and precipitation. This shield relies on a combination of plate geometry, material and natural ventilation to provide effective shielding. The radiation shield reflect sunlight from any direction, prevent sun direct radiation and reflection on the ground to the sensor radiation, to protect the instrument from the effects of strong winds, rain, snow, etc.Freely through the air, making instrument work in ventilated environment, to ensure the accuracy of measured data.Products with high reflectivity and low thermal conductivity, resistance to ultraviolet ray function, can be used in extreme weather conditions.

The pH value is one of the most commonly used water quality testing indicators. The pH value of natural water is mostly in the range of 6-9; the pH value of drinking water is required to be between 6.5 and 8.5; the pH value of some industrial water should be guaranteed to be between 7.0 and 8.5 Otherwise, it will have corrosive effects on metal equipment and pipelines. pH value and acidity, alkalinity are both different and connected. The pH value indicates the strength of the acidity and alkalinity of the water, and the acidity or alkalinity is the content of acid or alkali substances in the water. The change of pH in water quality indicates the degree of water pollution.

Electrical Conductivity Sensor is a new generation of intelligent conductivity sensor independently researched and developed by our company, with patent rights. It has the characteristics of high stability, superior repeat-ability, high measurement accuracy, etc. It can accurately measure the EC value, temperature value and TDS content in the solution, with 0~2V, 0~5V, 0~10V analog and voltage output, 4~20mA simulation Measure current output, digital RS485 communication output and other functions.

TSS Sensor integrated online suspension sensor is designed and manufactured using the principle of scattered light suspension measurement. When a beam of light is incident on a water sample, the light is scattered by the suspended matter in the water sample, and the scattered light in the water sample is calculated by measuring the intensity of the scattered light perpendicular to the incident light and comparing it with the internal calibration value , linearized to output the final value.

The BGT-SR rain and snow sensor is a qualitative measuring device that measures whether there is rain or snowfall outdoors or in nature. It can be widely used in the qualitative measurement of rain and snow in environment, greenhouse, aquaculture, construction, building, etc. It is safe and reliable, beautiful in appearance and convenient to install.

The Optical Rain Sensor  senses water hitting its outside surface using beams of infrared light. It uses the same sensing principle used in millions of automotive rain sensing windshield wiper controls. The Sensor  is optical-- not mechanical, chemical, or conductive.  Consequently, it is far more rugged, sensitive and reliable than any other technology. And the sensor is extremely sensitive, and virtually immune to false trips.In addition, it is completely unaffected by jostling and motion. There are no exposed conductors to corrode, and no openings for bugs to crawl into. And there is no place for leaves or other debris to collect.

The instrument adopts advanced and reliable integrated circuit which designed to complete the internal signal measurement part.

The series is FMCW radar operating at 76-81 GHz, which has a maximum measuring range of 120m and a minimum blind zone of 8cm. It supports 4-wire and 2-wire applications. Higher operating frequency and shorter wavelength make it ideal for solid applications,including those with extreme dust and high temperature to + 200?. The radar consists of an electronic circuit coupled to a lens antenna and flange for quick and easy positioning.
