- Stock: Pre-Order
- Model: 0.3 μm, 0.5 μm, 0.7 μm, 1.0 μm, 2.5 μm, 5.0 μm, 10 μm
The PMS 31 is a high-precision remote particle
counter designed for professional cleanroom and industrial air quality
monitoring. Built for reliability and accuracy, it features a 7-channel
particle size detection system and a powerful built-in 28.3 L/min
vacuum pump for high-volume sampling.
Engineered with industrial-grade components, the PMS 31
delivers stable, long-term operation in demanding environments such as
semiconductor, pharmaceutical, and precision manufacturing facilities. Its
metal housing ensures durability and strong anti-interference performance.
All instruments are ISO 21501 and JJF
1190-2008 compliant, ensuring measurement traceability and consistency
with global standards.
