SL355 Personal Noise Dosimeter/Datalogger by Extech
Features
- Perform OSHA and IEC Noise accumulation surveys
- One user-defined measurement setup
- Adjustable Criterion Level, Exchange Rate, and Threshold
- Applications include Personal accumulated noise exposure measurement, Workplace noise assessment, OSHA and other regulatory agency compliances
- Measures frequency weighted noise exposure and peak sound level simultaneously
- Datalogs up to 12,000 readings when used as a sound level meter with sampling times between 1sec and 1hr
- In sound level mode, meter displays sound level, time-averaged sound level (Leq), peak, and sound exposure level (SEL)
- Optional 94/114dB calibrator to perform "before" and "after" calibration checks per ANSI standards
- Stores up to 20 dosimeter surveys. Data includes Start/Stop Time, %Dose, %Dose projected for an 8 hour period, and peak level when used in the Dosimeter mode
- USB interface with Windows® XP/Vista/7 compatible software to control setup and retrieve stored events or analyze real time measurements
- Includes belt clip, clip-on 0.5" microphone with 2.6ft (0.8m) cable, 3 AAA batteries, mini screwdriver, software, USB cable, and carrying case
| Applicable Standards | IEC 61672-1:2005, IEC 61252:2000, ANSI S1.25 – for dose meter and sound exposure meters IEC 60651 – 1979 Type 2 for sound level meters IEC 60804 – 2000 Type 2 for integration sound level meters ANSI S1.4 – 1983 Type 2 for sound level meters ANSI S1.43 – 1997 for integrating sound level meters |
| Microphone | 1/2-inch electret condenser microphone with 31-inch integral cable. |
| Display | Liquid Crystal Display |
| Measurement Ranges | Linearity and Indicator ranges at 4 KHz (IEC 60804): 60 – 130: 60 – 130dB (A and C); 70 – 140: 70 – 140dB (A and C) Peak Ranges: 'C' Frequency Weighted Peak or Linear (Z) Peak over the top 40dB of each range: 60 – 130db: 93 – 133dB Peak; 70 – 140db: 103 – 143dB Peak |
| Frequency Weighting | RMS Detector: 'A' or 'C'; Peak Detector: 'C' or 'Z' (flat or linear). |
| Response Time Weighting | Fast and Slow (RMS detector). |
| Exchange Rate (Q) | 3, 4, 5 or 6 db |
| Stabilization Time | 10 seconds after the meter is switched on. |
| Threshold and Criterion Levels | Threshold Level: 70 – 90dB in 1dB steps; Criterion Level: 80, 84, 85 or 90dB. |
| Overload Indication | 0.1dB above the selected measurement range. |
| Under–Range Indication | 1dB below the selected range. |
| High Level Detector | 115dB |
| Clock | Real-time clock with calendar. |
| Memory | 20 noise surveys can be stored. |
| Measurement Control | Measurement Duration may be set to 5, 10, 15, or 30 minutes or 1, 2, 4, 8, 10, 12, or 24 hours. |
| Timers | Up to 5 timers (automatic start and stop) can be set (maximum up to one month ahead of measurement time). Timer Controlled Start/Stop: Configured using PC software or meter keypad. |
| Logging | All measurement parameters values can be logged, if the Logging Period is ≥ 1 minute. |
| Logging Period (LP) | Seconds: 1, 2, 5, 10, 15, 20, or 30; Minutes: 1, 2, 5, 10, 15, 20, 30, or 60. |
| Logging Capacity | The meter can log 14400 total values spread over 20 memory locations (RUNS). |
| PC Interface method | USB interface (meter-to-PC cable included in kit) |
| Battery | Three (3) 1.5V 'AAA' batteries |
| Battery life | Typically > 35 hours at room temperature. The instrument will automatically stop measuring and store its data before the battery voltage falls below the cut-off value. |
| Battery Indicator | Battery voltage level is represented in 4 stages using a displayed battery symbol. |
| Battery Backup | 3V lithium battery (CR1220) |
| Operating Temperature & Humidity | 0 – 50°C (32 to 122°F); 10 - 90%RH |
