What is an inline thermal mass flow sensor for gases and how does it work? A thermal flow sensor uses the thermal properties of gases to measure their mass flow rate. To this end, heat is introduced into the flowing gas, and the (temperature) sensor measures how much heat is absorbed by the gas. A traditional way of accurately measuring low gas flow rates is to use a mass flow meter with the ...
Monitoring particle levels is crucial to maintaining cleanroom integrity and ensuring product quality across many industries. Among the tools used, handheld particle counters stand out for their versatility, ease of use, and practicality. Here’s a straightforward look at understanding handheld particle counting - what it is, why it matters, and when it’s the right choice. ...
Keeping compressed gases clean and contaminant-free is a critical step in maintaining product quality and compliance, especially in sensitive industries like semiconductors and pharmaceuticals.

In this application, total suspended particulate (TSP) samples were collected using a medium-flow air sampler with imported 0.8Dum glass fiber microfiltration membranes. After sampling, the filters were stored in a desiccator. Microwave digestion was employed as the pretreatment method, offering rapid sample decomposition while ...
Atmospheric NO and NOy monitoring during in-flight research missions has become an essential tool for understanding the complex chemistry of the upper troposphere and lower stratosphere. The ECO PHYSICS CLD780TR analyzer plays a crucial role in these measurements, offering high precision and reliability for airborne applications. ...
Thermal mass flow sensor for gases - inline principle A thermal flow sensor uses the thermal properties of gases to measure their mass flow rate. To this end, heat is introduced into the flowing gas, and the (temperature) sensor measures how much heat is absorbed by the ...
When it comes to viable sampling in cleanrooms and critical spaces, you’ve got two main media options: traditional petri plates and Rapid Micro Bio (RMB) cassettes. Both get the job done, but they do it in very different ways—and depending on your setup, timelines, and data requirements, one may be a much better fit than the other. Let’s break down the real-world reasons ...
It is estimated that every 30 seconds, somewhere in the world, one worker dies as a result of exposure to toxic chemicals, pesticides, radiation and other hazardous substances.1 The effects of exposure can develop quickly or take years to develop, leaving workers vulnerable to asthmatic and allergic reactions and longer-term illnesses such as cancer and cardiovascular, respiratory and nervous ...
