ILT77 Germicidal UVC Light Meter / Radiometer

The use of germicidal low-pressure mercury lamps for UV disinfection has rapidly expanded into a wide array of industrial, commercial, and municipal applications such as HVAC, food processing and water treatment.

The increasing popularity of these UV disinfection lamp systems has created a requirement for a simple, economical, yet highly accurate means of monitoring the lamp output to ensure their peak germicidal effectiveness.

The ILT77 Germicidal UV-C Light Meter / Radiometer was specifically designed to easily and directly measure the output from conventional low pressure mercury germicidal lamps only. The included XP77 detector comes with three foot cable and a teflon diffuser.

The system measures a spectral range of 214 to 360 nm ("UVC") with a NIST traceable calibration.

The meter has a 4½ - digit display handling up to 199.99 mW/cm2, with a resolution of 0.01 mW/cm2. Readings are taken using a single button, and the meter shuts off automatically after 2 minutes to preserve the life of the 9 volt battery. It is enclosed in a removable cushioning boot (not shown) that protects the unit from accidental falls and acts as an instrument stand or hanger.

Each system is individually calibrated to NIST-traceable standards and is supplied with a calibration certificate.
