Air Quality Detection Meter

Air quality monitors detect the concentration of pollutants such as particulate matter and volatile organic compounds in the air through sensors, and are used for indoor and outdoor environmental monitoring as well as air quality assessment in industrial settings.
Selection
When selecting, consider whether the detection parameters cover common pollutant types at the site, pay attention to sensor accuracy and calibration cycles, check the equipment's protection rating to ensure it suits the usage environment, and compare data output methods to see if they meet recording requirements.

Determination of Thermal Decomposition Temperature and Inorganic Filler Content in Ink by Thermogravimetric Analyzer
This article introduces how to determine the thermal decomposition temperature and inorganic filler content of ink using a thermogravimetric analyzer. During the test, a small amount of ink sample is heated in a nitrogen or air atmosphere, and the mass change curve is recorded.
Rotation Speed of Sample Rack in Hot Air Aging Test Chamber on Color Fastness of Textiles
This article explores the influence of the rotation speed of sample racks in a hot air aging test chamber on the color fastness testing of textiles. The rotation speed affects the flow of hot air and temperature uniformity inside the chamber, thereby altering the heating conditions of the samples and leading to variations in color fastness results.
Difference between Black Panel Temperature and Black Standard Temperature in Light Aging Test Chambers
In the light aging test chamber, black panel temperature and black standard temperature are two distinct temperature indicators. The black panel temperature is measured using a black metal panel sensor, reflecting the immediate heating effect on the material surface under light exposure and is significantly influenced by air convection.
Hot air aging oven measures the long-term thermal-oxygen life of engineering plastics.
This article introduces how to use a hot air aging oven to test the long-term thermal-oxidative lifespan of engineering plastics. The test is based on the Arrhenius equation, which accelerates material aging at high temperatures to simulate performance changes under actual usage conditions.
Positive pressure method seal tester evaluates packaging pressure resistance
This article introduces how the positive pressure method sealing tester evaluates the pressure resistance of packaging. The instrument simulates actual pressure conditions by injecting compressed air into the packaging and then monitors pressure changes to determine if there is any leakage.
Negative pressure method leak detector for testing vacuum packaging seal integrity
The negative pressure leak detector evaluates the seal integrity of vacuum packaging by simulating a pressure differential environment. The instrument places the sample in a testing chamber and creates a vacuum to form negative pressure. If there is a leak, air or liquid will seep into the packaging, and the result is determined by observing pressure changes or the presence of bubbles.
Sheffield Smoothness Tester for Analyzing Paper Printing Surface
This article introduces how the Sheffield smoothness tester analyzes the printing surface of paper. The instrument quantifies paper smoothness by measuring the air leakage time, with a longer time indicating a smoother surface.
Schopper air permeability tester measures paper air permeability.
The Schopper air permeability tester measures the air permeability of paper based on Poiseuille's law, calculating the permeability by either the air flow rate under a constant pressure difference or the pressure difference at a fixed flow rate.
What is the difference between the Bendtsen method and the Gurley method for measuring paper air permeability using an air permeability tester?
The air permeability of paper is a key indicator for evaluating its structural compactness and suitability, especially crucial in fields such as packaging, filtration, and specialty papers. The Bendtsen and Gurley methods are two classic and widely used techniques for determining paper permeability.
What are the differences between a vacuum oven and a conventional oven?
The main difference between a vacuum oven and a conventional oven lies in their working pressure. Conventional ovens operate at atmospheric pressure, heating through air convection, making them suitable for routine drying tasks. In contrast, vacuum ovens are evacuated to low pressure to reduce air presence, primarily relying on thermal radiation for heat transfer. This makes them ideal for processing heat-sensitive, oxidation-prone materials or those requiring thorough drying.
