The CEL-254 uses a large digital display with full 0.1dB resolution to guarantee easy, precise reading.
Digital Impulse Sound Level Meter, Model CEL 254
The CEL-254 Digital Impulse Sound Level Meter is specially designed to meet the sound survey needs of industrial hygienists and safety professionals.
The CEL-254 uses a large digital display with full 0.1dB resolution to guarantee easy, precise reading.
The sound level meter is equipped with both ¡°A¡± and ¡°C¡± frequency weightings to take advantage of the increasing use of hearing protection Noise Reduction Rating (NRR) which simplifies the selection of Hearing Protectors.
Just two measurement ranges, both covering a 70dB span, are needed to achieve a 30dB-135dB(A) total measurement span so that a single range of 65dB-135dB is available for industrial surveys.
The meter complies with both the IEC 651 and ANSI S1.4 1983 in the Type 2 categories by providing both Fast and Slow response times. In addition, an Impulse response is available for those territories with extra legislative control over impulsive noise. The Impulse response is normally used in conjunction with the Maximum Hold function and this combination is equipped with a rapid reset facility. To optimize measuring opportunities ¡°maximum hold¡± is also operational on both Fast and Slow responses.

Digital Sound Survey Meter, Model CEL 231
The CEL-231 is a simplified version of the CEL-254 maintaining much of the specification. Fast and Slow time weightings are provided along with ¡°A¡± frequency weighting and a measurement range of 30dB(A) to 135dB(A). It will appeal to Safety Engineers and Occupational workers who require an easy-to-use survey instrument to check whether industrial noise exposure areas require more detailed investigation.
