Products Description
LPC-550 Large Flow Airborne Particle Counter
LPC-550 Airborne Particle Counter is a new particle counter with big flow rate,friendly interface and high-resolution color touch screen.LPC-550 Airborne Particle Counter is used to measure the particle size and count the number of particles. LPC-550 can finish sampling a cubic meter quickly and exactly in 20 miniutes,which is widely used in testing particles of clean rooms.
PRODUCTS FEATURE OF LPC-550 Large Flow Airborne Particle Counter
• 316L stainless steel housing, resistant to common disinfectants used in cleanrooms.
• 8-inch touchscreen for easy operation.
• Room names can be named in Chinese.
• By entering the cleanroom area, the system can automatically calculate the number of monitoring points required for the cleanroom.
