Basic General Purpose Sound Level Meter
The Casella CEL-240 is a low cost Type 2 sound level meter with the power of digital signal processing! Get a digital meter at an analog price. In need of a basic sound level meter? This is the unit. Possessing two measurement ranges that reach as low as 30dB and high as 130dB, it has the ability to capture A & C weightings at a Slow, Fast, and Impulse response timed. This makes the Casella CEL-240 ideal for industrial hygiene measurements whether it be a machinery noise surveys or a general purpose workplace noise level measurement.
The meter features the instantaneous sound level plus the maximum hold feature on all screens plus a real-time bar graph display. In a situation where noise levels are constantly varying, the time history trending graph will be useful for seeing the noise levels of short events.
The Casella CEL-240 features a 128 x 128 pixel LCD screen with two large buttons for simple operation. Calibration is as simple as well: connect the calibrator to the unit and turn both the calibration device and CEl-240 on. The Casella CEL-240 will instantly recognize the calibrator and perform calibration. The simplicity of this unit is great for both experienced and new users.
This Casella unit has a low-power consumption microprocessor. In fact, a set of 3 AA batteries will last for more than 35 hours in this Casella unit at room temperature. Not only is the Casella CEL-240 a quality unit but it is inexpensive to run.
The Casella CEL-240 series possesses different configurations for your specific application.
The Casella CEL-240 series contains 4 different models The Casella CEL-240 is the base version in the series which satisfies the accuracy standards of ANSI S1.4 and IEC 61672 type 2. The Casella CEL-242 is the data logging version of the CEL-240. The CEL-244 has all of the features of the CEL-240 with the addition of time averaged values Leq or Lavg. The CEL-246 is the data logging version of the CEL-244. View a model comparison chart here. Standard measurement kits denoted by K1 or optional computer output kits denoted by K2 are available, which are complete monitoring packages that include a calibrator, storage/travel case, and accessories (visit Casella).
