CEL-350 Personal Noise Dosimeter

CEL-350 dBadgeThe series personal noise dosimeter is an ideal tool for measuring personal noise exposure levels in the workplace. By adopting the latest digital technologyCEL-350 dBadgeThe various performance levels have reached a new level in the field of noise exposure dose measurement, which can meet the precise measurement of individual noise exposure levels in various occasions.

Unlike traditional wired noise dosimeters,CEL-350 dBadgeThe series of personal noise dosimeters extensively utilize intelligent technology, featuring easy operation, automatic measurement and data storage, wireless data transmission and export. The overall structure is lightweight and sturdy, without connecting wires, and weighs only71g. UseCEL-350No other external devices are required, and the entire operation process can be completed through the buttons on both sides of the instrument.

CEL-350The body integrates memory and battery, which can synchronously measure and store all noise parameters in the workplace. The data can then be downloaded toPCMachine, there is no need to set up the equipment before measurement and there is no risk of measuring incorrect parameters. Large capacity nickel hydrogen batteries can not only90Fully charged within minutes, while providing excellent battery life, coupled with large memory capacity to ensureCEL-350Continuous measurement of continuous shift work sites without frequent charging or data export.

In addition, for all different types of work environments,CEL-350Various auxiliary fixture options are also provided, enablingCEL-350It can be easily worn on employees' shoulders or safety helmets, and is comfortable to wear without affecting their work status.
