Description
The quality of the air we breathe, whether in offices, hospitals, manufacturing facilities, or residential buildings, has a profound impact on health, comfort, and operational processes. While many air quality parameters are measured, the concentration of airborne particles is one of the most critical yet often invisible factors. These particles, ranging from dust and pollen to mold spores and microscopic contaminants, can affect respiratory health, interfere with sensitive manufacturing processes, degrade product quality, and even impact the efficiency of HVAC systems. Visually inspecting air offers no insight into the microscopic world of particle pollution. HVAC and Indoor Air Quality (IAQ) professionals require sophisticated, reliable tools to accurately quantify airborne particle concentrations, enabling them to identify sources, assess risks, verify filtration performance, and ensure compliance with standards. Addressing this need requires an instrument that is not only accurate and sensitive but also practical for use in diverse, real-world environments, moving beyond simple presence detection to precise quantification and analysis of particle levels to inform necessary actions and maintain healthy and productive environments for occupants and sensitive processes alike in various commercial and industrial settings.
Comprehensive Measurement Across Particle Sizes
Accurately assessing air quality necessitates the ability to count and size particles across a significant range, identifying both larger, visible dust and pollen as well as smaller, respirable particles that pose health risks or impact critical manufacturing processes. The Fluke 985 Particle Counter is engineered with this comprehensive measurement capability in mind, featuring six channels that simultaneously count particles in distinct size ranges from 0.3 to 10.0 µm. This wide particle size range is particularly crucial as different particle sizes behave differently and have varying impacts. Particles in the 0.3 µm range are often associated with combustion or manufacturing processes, while larger particles like pollen or mold spores fall into higher ranges. By analyzing concentrations across these six specific channels, the 985 provides a detailed profile of airborne contaminants. This granular data is essential for understanding the composition of particle pollution and is a fundamental requirement for assessing and certifying critical locations according to international cleanroom standards, specifically ISO Class 5 through 9. The accuracy provided by measuring distinct size ranges assures that professionals have the precise data needed to meet stringent regulatory requirements and confidently verify the performance of high-efficiency filtration systems designed to control particle levels in sensitive environments like pharmaceutical production areas, electronics manufacturing, or hospital operating rooms, ensuring compliance and safety standards are met with reliable data.
Designed for Professionals, Engineered for Ergonomics
Fieldwork, whether investigating an occupant complaint in a cramped office or monitoring a large cleanroom, demands tools that are not only powerful but also easy and comfortable to use over extended periods. The Fluke 985 Particle Counter excels in this regard with its ultra-lightweight and ergonomic design. Weighing just over a pound, the meter minimizes strain during prolonged use. Its shape and balance are carefully designed to promise easy single-hand operation, a critical advantage when navigating tight spaces, reaching into ductwork, or maneuvering in awkward positions that are common in HVAC and IAQ investigations. Reducing operator fatigue is a direct benefit of this thoughtful design, allowing technicians to perform more tests over the course of a day without discomfort. This ergonomic superiority means the tool feels natural in the hand, enabling more stable sampling and reducing the likelihood of errors caused by awkward positioning or fatigue. By focusing on the user’s physical experience, the Fluke 985 ensures that its advanced measurement capabilities are fully accessible and can be utilized effectively in any environment the job demands, from elevated platforms to confined mechanical rooms, making it a practical and indispensable tool for professionals who spend significant time performing measurements in varied and sometimes physically challenging locations within buildings or facilities.
Endurance and Clarity for a Full Workday
Reliability in the field means having a tool that lasts as long as the job does and presents information clearly. The Fluke 985 is built for endurance, offering a long battery life of ten hours of standard use. This extensive operating time is designed to easily last a full work day on a single charge, allowing technicians to complete comprehensive site surveys or multiple investigations without the interruption of needing to recharge the device. This sustained power capability is essential for maintaining workflow efficiency and ensuring the tool is always ready for use throughout the day’s tasks. Complementing its battery life is a large 3.5 QVGC color display. This bright and spacious screen significantly enhances usability, providing easy navigation through the meter’s functions using intuitive icons. The display also features large font options, ensuring that measurement data is clearly visible, even in varying lighting conditions or when viewed from a slight distance. The combination of long-lasting power and a clear, easy-to-read display ensures that the Fluke 985 is a reliable partner in the field, ready to capture and display critical particle data throughout lengthy inspection cycles without causing eye strain or requiring frequent pauses for recharging.
Intelligent Data Handling and Customization
Effective particle monitoring involves not just taking measurements but also managing, analyzing, and interpreting the collected data to identify trends, pinpoint problem areas, and document findings. The Fluke 985 is equipped with intelligent data handling capabilities to streamline this process, featuring a substantial 10,000 record storage capacity. This ample storage allows technicians to save a large volume of historical data directly on the device, providing quick access to past readings for comparison, trending analysis, or reporting purposes without the immediate need to offload data. The meter also offers versatile on-screen data presentation, allowing data to be viewed in either a traditional tabular format for detailed numerical review or as a trend graph view, enabling users to quickly visualize changes in particle concentrations over time or across different locations. Further enhancing its usability are personalized settings and configurations, allowing customization of the display, sample methods (e.g., sample duration, delay), and alarm settings for sample count thresholds. These customizable settings ensure the meter can be tailored to specific testing protocols, alarm based on defined particle limits, and present information in the user’s preferred format, making data collection and initial analysis highly efficient and user-driven directly in the field.
Streamlined Data Export and Enhanced Security
Getting data off the device and into reports or analysis software should be a seamless process. The Fluke 985 offers multiple convenient data export options to ensure flexibility and ease of use. Users can easily download collected data to a PC using a standard USB memory stick, a direct USB cable connection, or via an Ethernet connection. A significant advantage is that no special software is required to download or view the data once transferred; the files are typically in a universally compatible format that can be opened with standard spreadsheet or text editing programs, simplifying the review and analysis process anywhere, anytime. This accessibility streamlines the workflow from measurement to reporting, reducing administrative burden. For environments requiring data integrity and restricted access, the Fluke 985 includes an optional password control feature. This confirms security when required, preventing unauthorized access to settings or stored data, which is particularly important in regulated industries or multi-user environments where maintaining data security and preventing tampering is paramount. Acquiring a genuine Fluke 985 with these integrated data handling, export, and security features functioning as designed is crucial for reliable operation and data integrity.
