Features & Applications:
The Casella Digital Impulse Sound Level Meter is ideal for the user who is new to noise measurement and those who only require an overall reading of the noise level to gain a better understanding of a noise problem.
The Casella Digital Impulse Sound Level Meter has all the capabilities of the Casella Digital Sound Survey Meter with the added benefit of a maximum hold facility to capture the highest level during the reading. The Impulse time weighting is also provided together with an on screen overload indicator that warns of any noise readings above the current range of the instrument.
The battery voltage level is switch selectable to allow the operator to monitor the condition of the batteries at any time during the measurements. In addition to the standard 'A' weighting the Casella Digital Impulse Sound Level Meter is also provided with the 'C' broadband weighting allowing the meter to be used for a wider range of measurement tasks that call for both 'A' and 'C' frequency weightings.
Features:
- Lightweight and slim design fits in the pocket
- Two wide measurement ranges cover all noise levels between 30 and 135 dB(A)
- Slow, Fast and Impulse responses available
- 'A' and 'C' frequency weightings cover most applications
- Long battery life using 4 AAA alkaline cells
- Overload and battery voltage checks provided
- AC and DC outputs provide analog signals to other pieces of equipment
- Includes Certificate of Conformance
