Features the sensitivity of larger instruments and easy handheld operation. Counts two sizes of particles; the second size is user-selectable. Configure sample times from one second up to 24 hours. Automatic shutoff when the battery charge drops below a safe operating level to maintain power to preserve data.
-0.3 micron sensitivity (227B) or a 0.5 micron sensitivity (227A)
-Counts two sizes of particles
-Compatible with PortAll Version 2 software
