FEATURES
Frequency and time weighting meet IEC 61672 class 1.
A & C weighting networks comply with standards.
0.5" standard microphone head.
Time weighting (Fast & Slow) dynamic characteristic modes.
Build External calibration VR.
Auto range & Manual range selection.
Available for external calibration adjustment.
Condenser microphone for high accuracy & long-term stability.
Memory function to store the Max. & Min. value.
Hold and Peak Hold functions.
Real time SD memory card Datalogger, it Built-in Clock and Calendar, real time data recorder , sampling time set from 1 second to 3600 seconds.
Manual datalogger is available ( set the sampling time to 0 ), during execute the manual datalogger function, it can set the different position ( location ) No. ( position 1 to position 99 ).
Innovation and easy operation, computer is not need to setup extra software, after execute datalogger, just take away the SD card from the meter and plug in the SD card into the computer, it can down load the all the measured value with the time information ( year/month/date/ hour/minute/second ) to the Excel directly, then user can make the further data or graphic analysis by themselves.
