UV integrator PCE-LM 100UV

Description
Precise UVC intensity and energy meter for professional UVC measurements and validation of disinfection processes. Designed for accurate measurement of UVC radiation (spectral sensitivity 230 nm to 280 nm, peak at 254 nm). High-precision UVC filters and a professional UV sensor minimise interference from other wavelengths. The instrument displays real-time, maximum, minimum and average values and reports measurement duration and accumulated energy for reliable monitoring and documentation of UVC exposures. Automatic data logging secures readings during long or unattended measurements. A USB-C port enables connection to a PC; dedicated PC software supports data export and report generation. Suitable for testing and monitoring UV disinfection systems in medical facilities, laboratories, pharmaceutical production, food processing and water, air and surface disinfection installations. Complies with standards JJG 879-2015 and WS/T 367-2012.
