Fluke 985 | Six-Channel Airborne Particle Counter for IAQ & Clean Areas

Dust and airborne contamination can reduce indoor air quality, indicate poor HVAC filtration or compromise controlled production environments. The Fluke 985 Airborne Particle Counter measures airborne particles across six size channels from 0.3 µm to 10.0 µm, giving HVAC and IAQ professionals quantitative information for contamination assessment.

Its 2.83 L/min sampling flow supports repeatable particle measurements, with results displayed as raw counts or concentration units in cumulative or differential modes. It can store up to 10,000 records internally and export them via USB or Ethernet without specialist download software. The 3.5-inch colour display can present results as tables or trend graphs, while user-configurable alarm thresholds help identify locations exceeding selected particle limits.

Particle Counter Selection Guide

Choose the 985 when the application requires actual particle concentration and size distribution, rather than temperature/humidity measurements alone. Its six-channel design suits HVAC, IAQ, and controlled-environment investigations.

Market Relevance

The Fluke 985 is particularly relevant to Pakistan's pharmaceutical production, hospitals, laboratories, clean manufacturing, HVAC commissioning and critical facility environments. Buy the Fluke 985 from Kamadi Pakistan for professional airborne-particle monitoring and filtration assessment.

Professional Tip: Establish a clean baseline before investigating an IAQ complaint; one particle count is far more useful when you can compare it against a known normal condition for the same location.
