UVC Light Meter for 253.7nm Germicidal Lamp Intensity Measurement – GAOTek
Description
Description
Overview
GAOTek UVC is also known as short wave sterilization ultraviolet light. 253.7nm wavelength ultrav iolet radiation from low pressure mercury lamp is widely used in ultraviolet sterilization industry. The UV light meter is specially designed to measure UVC intensity and energy values, which is widely applied in hospitals, CDC, pharmaceutical companies, F DA, etc for UV intensity and energy measurement.
Features
- Specially designed for 253.7nm UV germicidal lamps (low pressure mercury lamps).
- Rich statistical functi ons, simultaneous display of current value, maximum value, minimum value, average value, measurement pe riod, and energy value
- Data storage automatically before timing shutdown, which makes unattended measurements possible.
- High precision UVC optical filters and professional UV sensor, which allow the instrument to almost give no response to other wavebands
- Equipped with USB interface and dedicated PC software featured with parameter configuration, data reading, exporting of UV power data to EXCEL, report generation functions.
- Advanced digital probe technology, by which analog signal conversion to digital signal on the probe.
