The 897 Dosimeter Sound Measuring System...
conducts personal noise surveys to meet IEC and OSHA requirements. Used as a
sound level meter, the 897 provides a quick survey of targeted areas and identifies
suspect locations. The 897 is also ideal for industrial and environmental sound level
measurements and checking noise areas for excessive dB exposure.
Use the 897 to take measurements, or to view and print reports using a PC
computer or printer. Reports are automatically printed on a compatible PC printer
for later use during OSHA or other official inspections. Recorded data can also be
viewed on a personal computer monitor by using an accessory cable and other
manufacturer's software.
The 897 computes dosage and records up to 31 hours, at one minute intervals, of
Lavg and Lmax readings and the number of detected 140 dB peak occurrences per
minute.
