Simpson 897 Sound Dosimeter Measuring System

Simpson 897 Sound Dosimeter Measuring System 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 and record, then view 
and print reports from the computer by using HyperTerminal 
program for later use during OSHA or other official inspections.
NOTE: Microsoft no longer includes a HyperTerminal program 
on Windows 7.
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. You can then 
print data up to 8 hours of recorded readings.
