“… this is a fantastic particle sensor!   Battery operated so it’s very easy to use, you can’t go wrong with the price. NC

    Dylos Makes excellent laser particle counters because they’re precise, durable, easy to read and the battery operated unit is portable. I’ve been using this meter for over 5 years and continue to use it for testing air filters, HVAC systems, carpeting, blinds, bedding, crawl spaces and attics.
