GENERAL PURPOSE METERS The GOLDILUX range of ultraviolet meters are robust hand-held instruments, developed for measuring UV-A, UV-B and UV-C levels and doses. The meters are available as dedicated self-contained units or with remote, interchangeable plug-in probes. The highly stable UV-enhanced silicon detectors and the probe electronics ensure excellent linearity and stability. Good cosine response enables accurate measurements on extended sources. Features:

The GOLDILUX phototherapy instruments were developed for use during the therapy of neo-natal jaundice, caused by high Bilirubin levels in the blood. Exposure to blue light radiation in controlled intensities and for defined periods is the recommended treatment. The most efficient wavelength for treatment is around 450 nm. The lifetime of the lamps used for treatment is limited and the output of the lamps changes significantly with lamp age. To compensate for this change, exposure levels in incubators should be checked with a suitable meter on a regular basis to ensure consistent doses for the patients. BLUE LIGHT MEASUREMENT For effective treatment, the amount of therapeutically effective blue light to which the infant is exposed should be in the order of 5-10 W/cm. This quantity, in units of W/cm, is the therapeutically effective power from the lamp (in W) falling on each square centimeter of skin of the infant. The length of the exposure of the infant to the blue light depends on the age and condition of the baby, its response to the exposure and other factors as determined by the responsible physician. The factory calibration of the probe is performed at a distance of 800 mm from a spectroradiometrically calibrated phototherapy lamp, at a level of approximately 40 W/cm.The calibration lamp has its peak output at a wavelength of 450 nm. In order to ensure continued accurate readings from the probe, it should be re-calibrated by a competent laboratory at suitable intervals (yearly or as determined in accordance with the company quality system or as specified in applicable Government regulations).
The GOLDILUX range of smart radiometers or Smartmeters combines all the features of the existing general-purpose product range into microprocessor – controlled, hand-held units. The GRP-1 series of Smartmeters are designed for use with all types of CW radiation sources. Standard probes include photopic (light), UV-A, UV-B, UV-C and bilirubin. New probes for other UV, near UV and IR applications are under development (contact your representative for the latest details). All probes have a good cosine response, while the visible probes possess excellent photopic correction. As the probe’s nonvolatile memory stores its characteristics, one Smartmeter in combination with any of the above probes is sufficient for all measurements. Features:

Models:
TRANSMISSOMETERS Made for measuring the tint, or light transmittance, of transparent materials, such as car windscreens. Clear vision saves lives and road safety is important. Road traffic regulations in South Africa and in other countries have set minimum light transmittance levels for windows and windscreens of motor vehicles. The GOLDILUX transmissometer is currently being re-designed to update the light-source geometry and the electronics. The all-new instrument will be available by the end of 2003.
