Radiometer UVX

For easy measurement of UV lamp irradiance. The most effective way to monitor the lifespan and quality control of UV light sources.

The UVX radiometer is equipped with the latest in solid state electronics. It features a rugged housing, over-ranging and a low-battery indicator.

Compact UV measuring instrument with three optional Sensors for:

  • UV 254 nm (shortwave), measurement range: 250-290 nm
  • UV 310 nm (medium wave), measurement range: 280-340 nm
  • UV 365 nm (longwave), measurement range: 335-380 nm

UV Measuring Instrument UVX

The digital readout is in radiometric units with a broad dynamic range from 0.1 μW/cm² to 20 mW/cm² with accuracy and precision traceable to the National Institute of Standards and Technology (NIST).

The UVX radiometer is suitable for a wide range of research and industrial applications.
Typical applications using UV light sources include genetic experiments, photochemical reactions, sterilization procedures, optical laboratory measurements, experimental biology, dermatological research, non-destructive testing, and graphics procedures.

The UVX's range switch provides selection from three intensity ranges:

  • 0 - 20 mW/cm²
  • 0 - 200 mikroW/cm²
  • 0 - 2000 mikroW/cm²

Unit includes a port for attachment of a chart recorder (user provided).

The UVX is powered by a 9-volt battery, making it completely portable. (Battery sufficient for up to 120 hours of operation)
Not included.

The UVX series sensors are designed and calibrated for measurement of radiant incidences from line type and phosphor coated mercury arc source. Depending on the measuring range, select an appropriate sensor for your radiometer.

Optional Attenuator
A 10:1 attenuator extends the reading range to up to 200 mW/cm2.
The attenuator is used to enable measurements that require high UV light intensity without overloading the detector or producing false readings.
