Temtop PMD 351 aerosol monitor offers selected sensors and handheld devices useful in ensuring HVAC systems operate smoothly and efficiently. It can monitor particulates in the system to help ensure it is running cleanly and efficiently. Data from our monitors can help determine when maintenance is needed—whether that be duct cleaning, a filter change or other intervention. Temtop aerosol monitor is affordable and reliable.


Clean rooms and controlled environments rely on a limited presence of particulate matter to function properly. To confirm compliance in a controlled space, and to monitor conformance on an on-going basis, Temtop offers a range of portable handheld and small footprint bench-top particle counters. Our devices are reliable, cost-effective, and capable of measuring a range of particulate sizes from 0.3 to 10.0 microns. Temtop particle counters are used to qualify environments for certain manufacturing processes.


In certain manufacturing processes, reducing the number of airborne particles is critical. Yields drop dramatically when components and processes interact with dust, airborne microbes, aerosol particles, and trace moisture. To minimize defects and ensure consistent quality, Temtop offers a range of portable and small footprint particle counters and mass monitors. These devices are used to monitor facility functions and process controls. They are often an essential element of manufacturing quality assurance and control programs.

Temtop PMD 351 aerosol monitor can also work in Biological Monitoring, Controlled Environments, Dust Monitoring, Filter Testing, Food & Beverage, HVAC Applications (HVAC Control), Indoor Air Quality Monitoring. Industrial/Occupational Hygiene and Public & Workplace Monitoring.
