Q-meter low-e glass, window and film testing equipment (solar energy analyzer or light measurement)

Based on existing beam splitter type of instrument in the market, UTS developed its Q-meter with revolutionary new features:

• transmit UV (ultraviolet) light/transmit visible light/transmit IR (infrared) light (Tuv/Tvis/Tir) and reflection of visible light/ reflection of IR (Rvis/Rir) measurement, the first instrument in the market
• 3xAA 4.5V battery operation LED device, fully portable
• DC 5V socket available for long time operation with AC/DC adaptor
• Stable signal processing circuitry for non-drift readings under strong stray light
