Indoor Air Monitor

Indoor air quality monitors use sensors to detect the concentration of pollutants such as formaldehyde, PM2.5, and TVOC in the air. They are used for air quality monitoring in homes, offices, and other spaces to help understand environmental conditions and take appropriate measures.
Selection
When selecting, focus on whether the detection items cover common pollutants such as formaldehyde and PM2.5. The sensor type affects accuracy and response speed. Check the calibration cycle and error range. Consider data recording capabilities and ease of operation, and make a decision based on the usage scenario and budget.

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.

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.
