897 Sound Dosimeter/SMS-2 Kit
Designed for conducting personal noise surveys, the897 Dosimeter is versatile enough for the experienced hygienist butsimple enough for the novice technician. The data storage featureallows you to view reports on the computer or print them for uselater during inspections. Purchase the 897 by itself or in theSMS-2 kit with all of the relevant accessories, includingcalibrator, nose cone, microphone clip, wind screen, and serial andparallel printer cables.

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 oftargeted areas and identifies suspect locations. The 897 is alsoideal for industrial and environmental sound level measurements andchecking noise areas for excessive dB exposure.
Use the 897 to take measurements, or to view and print reportsusing a PC computer or printer. Reports are automatically printedon a compatible PC printer
for later use during OSHA or other official inspections. Recordeddata can also be viewed on a personal computer monitor by using anaccessory cable and other manufacturer's software.
The 897 computes dosage and records up to 31 hours, at one minuteintervals, of Lavg and Lmax readings and the number of detected 140dB peak occurrences perminute.
