• Bright LED’s (red flashing or green) alert user when sound level is too high or too low – LEDs can be read from 30m
• Continuous Monitoring of Sound Level
• Ideal for industrial, hospital, auditoriums, schools, and other areas where there is a need for being alerted when sound level reaches a set point
• Meets ANSI Type 2 and EN 60651 accuracy specs – compliant to OSHA
• User settable high or low limit (30 to 130dB) indication with output to drive external relay module
• Wall, desk, or tripod mount
• Microphone rotates 180° for desired placement. Optional 5m microphone extension cable for remote monitoring
• Complete with AC adaptor, microphone wind cover, wall, desk, or tripod mount (optional Tripod)

Extech SL130G Features Overview

Users can set the SL130G so the Red LEDs flash when the sound level is below the LO set point where people in the audience may not be able to hear. When the sound level is above the LO set point, the Green LEDs indicate the sound level is acceptable. You can reverse the Red and Green LEDs activation per user color preference.

Connectivity Options

Optional 5-meter microphone extension cable for remote monitoring.User settable high or low limit (30 to 130 dB) with output to drive an external relay module that can power a larger, remote indicating device such as a “Quiet” sign, or enable connection to an alarm system. Mount on a wall or tripod or set on a flat surface. Meets ANSI Type 2 and EN 60651 accuracy specs.

FLIR VP50 Non-Contact Voltage Detector Feature:

Enhanced Detection:

The FLIR VP50 Non-Contact Voltage Detector uses a low-profile probe tip that gets the sensor closer to electrical sources and enhanced sensitivity to help detect voltage in the latest safety outlets.

Powerful Worklights:

Intense (60-lumen) LED light source illuminates dimly lit locations – dual-LED convenience light at the probe tip lights up inspection targets.

Tactile Alarms:

Multi-color flashing LEDs and vibration alarms make it harder to miss the presence of voltage (up to 1000V) in noisy environments.

High/Low Sensitivity:

Detect voltage in electrical systems in large industrial facilities, residential low voltage installations, and systems located behind obstructions (using High Sensitivity mode).

Rugged & Durable:

Robust battery door and pocket clip design is engineered for long product life cycles, and the low profile detection tip bolsters a common weak point.

Technical Summary

Voltage Ranges 90 to 1000V
24 to 1000V
Category Rating CAT IV-1000V
Frequency Range 45 – 65Hz
Drop Test 3m (9.8’)
Built-in Flashlight Yes
Vibrating Indication Yes
On/Off Switch Yes
Warranty Limited Lifetime*

Using the Auto Power Off function
This instrument will shut off automatically in approx. 20 minutes for every power on. For recording or operating over longer periods of time, you can disable the sleep mode before power on.

Choosing the units
Pressing the “Unit” button, the units will cycle through “bar” ,”mmHg”,”ozin2″,”kgcm2″ ,”psi”,”inH2O”,”kPa”,”ftH2O” ,”inHg” ,”cmH2O” ,”mbar” ,which indicated on the bottom of the display.

Using the Differential Pressure Function
Simply press the DIF button and the “DIF” appears on top of the LCD and the display indicates the relative zero (Relative zero causes the value of the display to show as “0.0”)-only the amount of pressure change will be indicated. Press the DIF button again and the unit returns to the normal mode of pressure differential.
