1 lightness Brightness is the eye’s perception of the brightness of a light source and object surface. It is a visual experience mainly determined by the intensity of light. Generally speaking, the stronger the light, the brighter it looks; the weaker the light, the darker it looks. The extremes of brightness are white and black. The […]

Nitrogen oxides are one of the main pollutants of air pollution and are seriously harmful to human health. Relevant departments in various places have successively issued relevant policies for nitrogen oxide control and online monitoring of nitrogen oxide concentrations in gas boilers in key industries. At the same time, the data will be uploaded to

1. Overview of food safety detectors The food safety detector is an advanced equipment that integrates modern analytical chemistry, biology, optics, electronics and other multi-disciplinary technologies. It can quickly and accurately detect harmful substances in food, such as pesticide residues, heavy metal contamination, microbial content, excessive additives and illegal additives, etc., providing strong technical support

A hydrogen detector is an instrument specially used to detect hydrogen concentration. It can monitor the concentration of hydrogen in the environment in real time and issue an alarm when the concentration exceeds the standard. However, when we use hydrogen detectors, cross-interference sometimes occurs. Problems can affect the accuracy and reliability of the instrument. So

1. Brinell hardness tester: It is mainly used to test unquenched steel, cast iron, non-ferrous metals and soft bearing alloy materials, represented by HBW. 2. Vickers hardness tester: It is mainly used to measure the hardness of ferrous metals, non-ferrous metals, hard alloys (such as aluminum alloys) and surface carburizing and nitriding layers, represented by

Lumens meters, also known as light meters, are widely used in various industries to measure the brightness of light. With the advancement of technology, modern lumens meters are equipped with high-precision photosensitive sensors, which have fast response speeds and can accurately measure even the slightest fluctuations of light. Additionally, they come with large high-definition displays

Economy handheld combustible gas detectors are widely used in various scenarios. As a low-cost solution, these detectors have become popular in both residential and industrial applications. In home settings, combustible gas detectors are commonly used in kitchens, bathrooms, and laundry rooms to detect gas leaks from natural gas, propane, or butane appliances. These detectors are

Water quality analysis is an essential task for laboratory technicians and researchers. A key tool for such analyses is the handheld water quality analyzer. This type of device enables users to measure and monitor various water quality parameters accurately and reliably in the field or laboratory setting. One advantage of today’s handheld water quality analyzers

In recent years,  people have begun to pay more attention to the importance of air quality. To effectively monitor air quality, a portable dust quality detector has been developed that is capable of detecting 0.5um, 1.0um, 2.5um, and 10um dust particles. The detector has two detection modes: quality and quantity detection. In addition to dust

Pesticides are extensively used in agriculture for crop protection against pests, insects, and diseases. While these chemicals are essential for crop production, they also pose potential health hazards to consumers when residues remain in the fruits and vegetables during food processing and preparation. This is why it’s important to test for pesticide residues in produce
