Handheld Particle Counter – Portable device for measuring airborne particles in real-time to ensure air quality in industrial and cleanroom environments

Handheld Particle Counters

The handheld particle counter is an advanced instrument designed for precise particle counting in critical environments such as cleanrooms, operating rooms, filter testing, and indoor air quality (IAQ) investigations. Known for its innovation and accuracy, this model features advanced measurement technology for superior performance. The devices are equipped with a 4.3-inch full-color LCD touchscreen, ensuring a user-friendly interface for easy data interaction and interpretation. They support data transfer via USB, allowing effortless downloads of up to 10,000 records for analysis. Both models comply with ISO 21501-4 and are RoHS compliant, meeting global standards for particle counting and environmental safety. Key features include a minimum sensitivity of 0.3 microns, the ability to display multiple particle sizes simultaneously, and storage for up to a week’s worth of data. The models are compact, lightweight, and ergonomically designed for comfort during extended use. They also offer remote control software, allowing for monitoring and control via PC. Key Points: Measures multiple particle sizes, for upto 6 channels with a minimum sensitivity of 0.3 microns 0.1 CFM flow rate with ±5% accuracy Up to 10,000 measurements stored Large, 4.3-inch color touchscreen for easy data interpretation ISO 21501-4 compliant and RoHS compliant Ergonomically designed for extended use Remote control and easy USB data transfer
