Gigahertz X9-6

Measuring instrument for UV-A and UV-B

Instrument for UV-A, UV-B and UV-B311 irradiance and dose measurements.

Beside it´s precise measurement capability the X9-6 most outstanding feature is its easy handling. To measure, the user simply switches on the meter and selects either the CW (W/cm²) or Dose (J/cm²) mode. The LCD characters are 9 mm high for easy viewing. The X9-6 is a compact handheld battery operated instrument.

The irradiance detector head houses separate UV-A and UV-B detectors whose spectral sensitivity and cosine corrected field of view meet accepted UV-A and UV-B spectral standards.

The instrument calibration is traceable to the ISO EN 17025 accredited part of the Gigahertz-Optik´s Calibration Laboratory for Optical Radiation Quantities. Calibration of UV-A and UV-B irradiance sensitivity as well as an additional narrowband UV-B calibration at 311 nm for TL-01 type sources is supplied. Individually measured plots of the UV-A and UV-B spectral sensitivities are provided as part of the calibration certificate.
