Volatile Organic Gas Detector

Volatile organic gas detectors capture gas molecules through sensors, generating changes in electrical signals to achieve concentration measurement. They are used for rapid on-site monitoring of the volatilization of organic solvents such as benzene and ketones, ensuring workplace safety, and are commonly employed in environments like printing workshops and paint production lines.
Selection
When selecting, consider matching the sensor type to the types of gases being detected, clarify the range and resolution requirements, pay attention to the explosion-proof rating and protection standards, check the calibration cycle and data logging capabilities, and combine these factors with the adaptability to the environmental humidity and temperature, as well as the need for portable or fixed installation.

Circle method adhesion tester for evaluating the bonding strength of organic coatings
This article introduces how the circle method adhesion tester evaluates the bonding force between organic coatings and substrates. The instrument uses a stylus to draw a spiral line on the coating surface, and the adhesion level is assessed based on the number of circles before the coating begins to peel off. A smaller number indicates stronger adhesion.
Muffle furnace is used for the determination of coating loss on ignition and ash content.
A muffle furnace is a laboratory heating device used to determine the loss on ignition and ash content of coating materials. By incinerating the sample at high temperatures, the organic components decompose and volatilize, leaving behind inorganic residues as ash.
Thermogravimetric Analyzer for Determining the Solid Content of Varnish
The principle of determining the solid content of varnish using a thermogravimetric analyzer is as follows: when the sample is heated, volatile solvents and moisture evaporate, leading to a decrease in mass, while the remaining solid mass stabilizes. The solid content is calculated by comparing the initial and final mass ratios.
Use of Muffle Furnace for Ash Determination in Pulp Inorganic Matter Testing
This article introduces the application of the ash determination muffle furnace in the detection of inorganic substances in pulp. The muffle furnace removes organic matter in the sample through high-temperature combustion, and the remaining inorganic residue, known as ash, is used to analyze the content of fillers and metal ions in the pulp.
Operation procedure of hot melt adhesive ash content determination instrument
