Time counter

digitallaseroptical

This instrument is a hand-held, battery operated optical particle counter. It uses laser technology to measure particle concentrations (solid and liquid) in ambient air up to 0,0003 mm (0,3 µm) in diameter. The measuring result is clearly shown on a digital display. The data will be updated every six seconds as the instrument continuously measures the concentration of airborne particles. Ideal for the air testing before inspections and for exhaust air tests of filter units. Technical filter measurements Leak tests of HEPA filters Monitoring of filters in room ventilation systems Monitoring of release efficiency of indoor air cleaners Monitoring of dust retention capacity of vacuum cleaners Room air and environmental measurements Monitoring of clean rooms Assessment of airborne dust concentration indoors Detection limit: 0,3 µm Quantity measuring channels: 1 Measruing channels (µm): 0,3 Flow volume: 0,7075 l/min Measurement duration: 6 seconds, renewal every 6 Sec Measurement shown as: Particle per cubic foot or per liter Remote access: no Data storage: no Measuring time per battery charge: up to 4 hours Rechargeable battery: NIMH, charging time ca. 3 hours Dimensions: 10 x 19,5 x 5,5 cm Weight: 0,8 kg Scope of delivery: Transport case, isokinetic probe, purge filter, battery charger, instruction manual, calibration certificate
