The latest LSI circuit design and display technology is used to achieve the lowest possible component count. This, in turn, assures reliability, accuracy, stability, and rugged dependability. In combination with its functional and aesthetic design, the Gould-Bass DLM-1000 is the easiest to handle blacklight, and visible light measuring instrument available today. The “DigiGlo” LCD display provides constant fluorescent illumination with no battery draw.

Hocker Inc. is a manufacturer’s representative that serves many industries, including Aerospace, Petro-Chemical, Testing Lab, Turbine, and Drilling. We repair magnetic particle equipment, automatic film processors, and blacklights. Also, we provide our customers with certification and calibration services.

The light waves are refractedcloserefractionProcess by which a wave changes speed and sometimes direction upon entering a denser or less dense medium, eg a light ray changes direction when refracted by a lens. as they enter and leave the prism. The shorter the wavelengthclosewavelengthThe length of a single wave, measured from one wave peak to the next. of the light, the more it is refracted. As a result, red light is refracted the least and violet light is refracted the most - causing the coloured light to spread out to form a spectrum. This is called dispersionclosedispersionSpreading out of the different wavelengths of light, caused by refraction of light as it passes through a prism..

The Gould-Bass DLM-1000 Digital Radiometer is a portable, 3-1/2 digit instrument that measures either blacklight intensity in the spectral range of 320-400 nanometers in microwatts per square centimeter or visible light intensity of 380-700 nanometers (photometric response) in Lux or foot-candles, depending upon the sensor selected.
