= NEW Digital Concrete Air-Meter =: Air content in fresh concrete is commonly measured in the field using the pressure method. The pressure method is practical for field-testing most concretes.Original volume of Air in the sample is determined by the principle of Boyles Law.This Meter(DY-300) quickly determine percentage of entrained air in freshly mixed concrete. And has a multi-range feature to accurately measure entrainedair up to 9.9% by Digital Measuring System.1.Technology:-Measuring Target:Air content in freshly mixed conc-Measuring Method: Digital Measuring System by Micom-The principle of Measurement:Boyles Law-Air pressure sensor: Ceramic pressure cell, Max.200.0kPa-Air pressure Resolution: 0.1kPa-Measuring Range(Air content): 1>0.0%-9.9% 2>0.00%-9.99%(Selectable)-Accuracy(Air content): 25C.1>0.1% 2>0.01%-Resolution(Air content):0.1% / 0.01%-Measuring Temperature:0C-70C-Operating Temp/Humidity:0C-50C / 80% RH-Air content Calibration:2 points (0%-Zero / 4.5%-Span)-I.P Line:1>Water filled:100kPa 2>Waterless:98kPa-Air meter Bowl: 7L,Lightweight cast aluminium alloy-Compressor(compressed air pressure): Automatic pump up the air pressure(Compressed air pressure system by motor-operating: Max.120.0kPa/20 Sec.)-Display:128 x 64 LCD Graphic Display1>Air pressure:4 digit 2>Air content: 2 digit(3 digit:Selectable) 3>Temp.: 3 digit-Power Supply: Ni-MH x 8 Pcs, rechargeable-Battery Life: 20 consecutive times use-Adapter: AC110/220-60Hz, DC12V/500mA-Interface: 9,600 bps,8 data bit,No parity,1 stop bit-DIMS(LxWxH)/Weight:120x110x 125mm /Abt.1.0kg-Printer(Thermal): (Option)
