Main Features
 
 
Innovative design
 
CB012 calibrator is portable and very easy to use, which makes it useful for the verification of sound level meters (class 2) and dosimeters at the point of measurement and in the laboratory.
Its ergonomic design prevents the calibrator rolling when placed on a flat surface.
The CB012 is managed with just one button. And it has two LEDs (ON and 94 dB), both visible throughout the verification process, which keep the user informed of the level stability and also the state of the batteries.
 
Feedback loop
 
The operation of the CB012 is based on a feedback loop system. In this way, the level generated is independent of the environmental conditions in which the equipment is located.
In addition, this calibrator has a protection system that prevents the equipment from being turned on involuntarily, both after use and due to accidental power on.
