Overview

This specification refers to the Sound Level Meter TYPE6236.It covers ost easurands corresponding

to JIS and –ISO. TYPE 6236, provided with any functions usually ounted in equivalent products, has

been realized at an extre ely low price.

Measure ent of ost easurands, such as Equivalent continuous A-weighted sound pressure level (LAeq),

Sound exposure level (LAE), A-weighted sound pressure level (LA), etc., is possible.

The 6236 was developed to keep co fortable sound environ ent as well as safe and healthy life of people,

both to be realized by the evaluation of environ ental noise such as traffic noise or industrial equip ent

noise, or by better understanding of the labor health environ ent at offices, factories, etc.

The i pressive design of 6236 sy bolizes satisfactory operations and any perfor ances related to JIS

and/or IEC. It sure is a highly efficient and highly reliable sound level eter, to be supported by the next

generation.

Features

● Excellent cost/perfor ance ：covers ost easurands in current criteria

● Percentile sound pressure level (LN) ：any 5 selectable values is available

● Measure ent of Equivalent continuous A-weighted sound pressure level (LAeq)

：Measure ent of environ ental noise required to

secure occupational heal

● Wide linearity range of 100dB over ：Covers wide range of 20~130dB

● Equipped with an USB Ver2.0 function：allows data processing for PC

● Equipped with a e ory function ：recording to e ory card(SD card)

● Backlight LCD screen for high ：visibility and easy-on-the eye display

● Ti er function ：easure ent can be paused or restarted at any

point of ti e by installing the function.

● Abundant progra cards ：1/1and 1/3-octave Real-ti e analysis card,

FTT Analysis Card
