Basic Accuracy: Air Velocity, ± ( 2% + 0.2 m/ s) , ± ( 2% + 0.8 km/ h) , ± ( 2% + 0.4 knots) , ± ( 2% + 40 ft/ min) , ± ( 2% + 0.4 mph) ; Temperature, ± 1.5° F ( 0.8° C) 

Personal Noise Dosimeters EXTECH 407355

The Extech 407355 personal noise dosimeter is a low cost, lighweight and easy-to-use instrument for measuring total sound exposure over an 8-hour period. The Extech 407355 personal noise dosimeter is perfect for performing OSHA and IEC noise accumulation surveys. The Extech 407355 personal noise has an adjustable criterion level, exchange rate, and threshold. Up to 5 dosimeter surveys can be stored in the Extech 407355 personal noise dosimeter, and the data includes start/ stop time, % dose, TWA, and peak flags when in dosimeter mode.

When used as a sound level meter, the 407355 Extech 407355 personal noise dosimeter datalogs up to 4500dB readings. An optional 94/ 114dB calibrator is available to perform " before " and " after " calibration checks. The bi-directional RS-232 interface and the Windows ® 95/ 98/ NT/ 200/ ME/ XP compatible software can be use to control setup and retrieve stored events or analyze real time measurements. Included with the Extech 407355 personal noise dosimeter is an RS-232 cable, complete with 9 or 25 pin adaptor.
