Outdoor Noise Measurement Kits
Cirrus Research provides a range of outdoor measurement kits suitable for use with the CR:800A, CR:800C and CR:700B Sound Level Meters. These measurement kits can be purchased either as a complete kits which includes the appropriate Sound Level Meter and all of the accessories or as an individual kit which can be added to an existing Sound Level Meter.

These products form a complete package which includes the Sound Level Meter and the Outdoor Measurement Kit along with all of the accessories. This will mean that one order code will give you all the instrumentation and accessories needed. For example, EK:411C which will consist of CR:811C Sound Level Meter and the CK:408C Heavy Duty Outdoor Kit.
Each of the new “EK” Outdoor Measurement kits will contain the following items:
• Sound Level Meter
• Outdoor Microphone
