The KR-12A portable particle counter is a high-performance air particle detection device produced by RION, a renowned Japanese company. Widely used in cleanrooms, pharmaceutical industries, electronics manufacturing, food processing, and aerospace fields, it monitors airborne particle concentrations to ensure environmental quality meets relevant requirements.

The KR-12A features a six-channel particle size range, capable of detecting particles of 0.3, 0.5, 0.7, 1.0, 2.0, and 5.0 micrometers. Its optical system employs a 90° sideway light-scattering method with a laser diode light source, ensuring high-precision and reliable measurement results. The device is equipped with an integrated temperature and humidity sensor, providing users with comprehensive environmental information.

The particle counter uses a pressure sensor feedback circuit to automatically control the flow rate, maintaining a stable sampling flow of 2.83 liters per minute. Its internal battery supports continuous operation for up to eight hours, with a charging time of only two hours, making it suitable for long-term outdoor or mobile monitoring. Additionally, the device can store 500 data sets and transfer data to a computer via an RS-232C interface, facilitating data analysis and record-keeping for users.

The KR-12A portable particle counter also has the capability to connect to multiple monitoring systems and serial printers, allowing users to expand according to their actual needs. With dimensions of 116 mm (W) × 211 mm (H) × 65 mm (D) and a weight of approximately 1 kg, it is easy to carry and operate.
