3.1 UV254 Sensor
3.1.1 General Information
3.1.1.1 Health and Safety
The UV254 Sensor is designed to measure the absorbance and transmittance of UV light at a
wavelength of 254nm in water. The sensor is often used in clean water and waste water applications.
Health and safety precautions should be taken to protect against waste water when handling a used
sensor.
Before making or breaking any electrical or signal connections, ensure that the instrument
is isolated from the electrical supply.
Visually inspect the sensor prior to installation. If the quartz flow cell or UV lamp is broken or
damaged in any way, do not use. Contact your supplier for replacement parts.
Ensure that all responsible personnel carefully read this manual before installing or servic-
ing the UV254 sensor. Failure to properly install and maintain this device may impact the
effectiveness of the sensor.
The UV254 Sensor sensor contains a UV lamp, which emits light at the ultraviolet (UV) 254nm
wavelength.
Never look directly at the UV light source, as it may cause permanent eye damage and harm
unprotected skin.
3.1.1.2 Environmental Considerations
The sensor includes a mercury lamp and a ribbon cable that are replaced periodically. Please use
this product in a manner sensitive to the environment and at the end of its life dispose or recycle in a
manner appropriate at that time in compliance with local regulations.
