Used MET ONE R4000 #9104201 for sale

MET ONE R4000 is a laser particle counter designed for industrial and commercial air quality monitoring applications. Equipped with a single-head, non-dispersive infrared (NDIR) optical particle sensor, this particle counter is capable of measuring particles in six size classes between 0.3 μm and 20 μm to offer real-time monitoring of air quality in many environments. R4000 features a data logging function that can store up to 180 days of real-time particle counting data. Data can be downloaded via the MET-ENV software, which also provides intuitive graphical displays for easy analysis. Additionally, this particle counter is easily connected to a building automation system, allowing it to send data to remote locations in real time, as well as enable automated responses to changes in particle counts. This particle counter is designed to be easy to use, featuring an informative OLED graphical display. The OLED display includes an adjustable setpoint alarm, which triggers an audible alarm based on user-defined particle count thresholds. Additionally, a password function restricts unauthorized tampering with settings or data, ensuring that only authorized personnel can make changes to the counter. To ensure accuracy, MET ONE R4000 is built with an integrated temperature and humidity sensor. These measurements are taken before, during, and after every run to compensate for temperature and humidity variations that could affect particle count accuracy. R4000 is designed with highly accurate, reliable pulse discrimination technology, which is essential in particle counting applications. The device measures particle counts in six size classes and provides a linear response regardless of air flow conditions. This particle counter also features a low-flow sensor that automatically adjusts the flow rate needed to accurately detect particle concentration levels. MET ONE R4000 is designed with ease of use, portability, and durability in mind, making it suitable for a wide array of industrial and commercial air quality monitoring applications. It is lightweight and compact, allowing it to be easily installed in tight spaces, while the integrated filter assembly guarantees reliable and accurate results. Furthermore, this particle counter is certified to meet a variety of international standards.
