The MC-85 provides fast, accurate measurements of Sound Level from 30 to 130 dB. The A & C frequency weighting networks conform to the IEC 651 type 2 standard. 'A' weighting simulates the response of the human ear while 'C' weighting has a near flat response for checking vibration noises.
Fast and slow time weighting is also provided. 'Fast' response is similar to the response time of the human ear. 'Slow' response is used to obtain an average reading of vibration sound levels. The MC-85 can be calibrated from an external calibrator. An internal source is also provided for quick checks.
The LCD display has large, easy to read digits. A low battery warning is displayed when the battery requires replacement. A NiCad battery and charger option is available.
