Used MET ONE 227B #46655 for sale

MET ONE 227B is a state-of-the-art particle counter that is designed to effectively and accurately measure the concentration of particles in the air. This particle counter operates by drawing in ambient air samples and counting the total number of particles that are 0.5 μm to 20 μm in size. The air is then sampled multiple times and the results are averaged and reported as an ambient air concentration of particles. This particle counter is equipped with a particle-detecting laser, and a multi-channel optical head for counting particles of multiple sizes. It also has a built-in pump for drawing air samples and a thermostatically-controlled incubation chamber for maintaining a high level of accuracy in particle detection. The accompanying software allows operators to adjust the sample flow rate, set thresholds for high and low particle counts, and save results to a USB drive or to a computer. 227B is constructed from durable, corrosion-resistant materials, and its operating temperature range is between -20°C and +60°C. It also includes a detector temperature control that monitors the output of the optical channels to stabilize the detector output. Furthermore, it features an Auto-Flow Control System (AFCS) to ensure that the system is operating within the preset flow rate range. Furthermore, MET ONE 227B is designed to meet the highest federal and state air monitoring requirements, and is capable of producing results that are accurate to the ISO 21501-4 standard, even in challenging environments. The particle counter continuously tests the environment, and in the event of any conspicuous changes in the particle concentration, an alarm will sound. Overall, 227B is an efficient and accurate particle counter that enables users to evaluate airborne particle concentrations over a wide size range. It is tailored to strict international environment standards, and is built to perform reliably in challenging conditions.
