Crystal IS UVC LEDs can improve environmental monitoring over mercury-based lamps by offering ease of use across multiple water treatment environments because of the smaller footprint, the company says.
The LEDs fit directly in a pipe, in an open channel or used offline as a battery operated handheld instrument.
The company says they also offer high spectral quality for measurement linearity over a wide range and a long lifetime and simple drive electronics that enable maintenance-free, continuous remote operation.
Sensorex, which manufactures sensors for water applications, evaluated Crystal IS UVC LEDs as a light source replacement to mercury-based lamps. It is now introducing the first family of ultraviolet transmittance monitors using UVC LEDs.
Testing confirmed that brighter, longer lifetime UVC LEDs were a significant contribution to a UVT monitoring instrument that:
- is able to achieve full intensity instantly,
- optimizes UV disinfection dosage guaranteeing that systems are not under- or over-dosing water and
- reveals cost savings greater than the one-time cost of purchasing the UVT monitor.
