|Accuracy / Class:||Type II designed for field use Conforming to BIS 15575 (Part1) 2005|
|Measurement range:||34 to 134 dBA in three 50 dB overlapping ranges|
|Error indication:||Over Range, Under Range and Low Battery|
|Frequency Weighting:||“A” type as per IS 15575 (Part1) 2005|
|Time Weighting:||SLOW and FAST as per IS 15575 (Part1) 2005|
|Measurements:||Sound Pressure Level (SPL), MIN SPL, MAX SPL, LEQ, Sound Exposure Level (SEL)|
and run time continuously available on the display by selecting appropriate display screen
|Display:||LCD 16 Character, 2 Line Display with 0.1 DB resolution|
|Operation Modes:||Continuous and Recording|
In Continuous Mode SLM100 displays the current SPL level, LEQ, SEL etc. for the duration of current session of operation.
In Recording Mode, current values of above parameters are displayed on the screen and LEQ, MIN SPL, MAX SPL,
and SEL values integrated over a minute are recorded in the built-in data logger.
The SLM100 allows the user to record multiple files making it possible to make
a detailed survey at several locations before downloading data to a PC for Analysis
|Memory Capacity:||In built data logger can store more than 24 hours data (at 1 minute intervals) in non-volatile Flash Memory|
|Data Download:||In-built RS232 Serial Port for direct interface to a PC|

PC and makes the data available in an Excel Spreadsheet for analysis and report preparation
|Battery:||A re-chargeable NiMH battery pack allows operation for 10 hours or more. |
A built-in battery status facility allows the user to check useable battery
hours and automatically prompts the user when the battery is running low.
To prevent battery damage the instruments
SLM 109 is a Class 1 integrating sound level meter. It complies with the IEC61672 as well as ANSI S 1.4 standards. The instrument features an industrially designed housing and offers a high level of comfort and style.
The SLM 109 has a dynamic range of 100 dB and does not require range selection. It can measure three parameters simultaneously with the A, C, and Z frequency weightings and with Fast, Slow, and Impulse time weightings. The integration time for Leq, Ln and other integral sound quantities can be programmed from 1s to 24 hours.
The SLM 109 is the ideal choice for performing many kinds of noise measurement tasks, for example, in environmental noise, vehicle noise, industrial application, etc – specially where Class 1 accuracy is required.
