This is a self-contained system for use with standard sound level meters and is intended for temporary installations. Supplied with 3-metre cable and Lemo connector, includes desiccant unit (Gras-AL0001) and coupler (Gras-RA0010) for calibration with Nor-1251 or B&K 4230 acoustic calibrators and a mini-tripod for attended measurements. For unattended measurements, the CA-4007 heavy-duty tripod must be specified. Extension cables Nor-1408A are available in 5, 10 and 30-metre lengths

NOR-1212E Electret Outdoor Microphone Kit - £9 day rate

Comprises an assembly of a GRAS or B&K class 1 (precision) electret measurement microphone, a Nor-1201 preamplifier, Nor-1212 weather protection enclosure and a Nor-1408A 5 metre extension cable. It is therefore suitable for direct connection to a wide range of precision sound level meters from Norsonic or B&K as well as those from other manufacturers that use Lemo 1B connectors. The electret microphone is well suited to applications in damp environments. To prevent problems with the polarization voltage that may be supplied from the associated sound level meter the cable has been modified to remove this supply to the preamplifier.

The Nor-1212E microphone system is designed for temporary outdoor measurement situations using the Norsonic range of Sound Level Meters. It is supplied with an Electret type microphone and pre-wired 5-metre cable and designed for use with the CA-4007 tripod stand.

If used with the Nor-131 or Nor-140 Sound Level Meters the MTG-TA202 or Nor-1284 dehumidifier must also be specified. Also requires an extension cable to be specified on the order; type Nor-1408A (5, 10 or 30 metres) for use with Nor-116, 118, 140 or 121 or type CA-4532/5M when using the Nor-131.
