General Information about UV Light
Vilber_ Lourm UV Light Meters use a superior silicon photo-electric cell sensor with a pass-band filter which screens out infrared and visible light and allows in only UV light . This filter is protected by a quartz disk. The sensors contain no electronic components to avoid any possible temperature disparity and are attached to the meter via a 1m long carbon shielded cable. Vilber Lourmat meters are therefore completely insensitive to Infra red and visible light resulting in more accurate UV measurements than other meters on the market. These sensors also provide a very fast response time. All our UV light meters come with a hard shell carrying case, batteries, instructions, and a certificate of calibration to the standards of the Laboratoire National D’Essais the French equivalent of the U.S. N.I.S.T.
The following meters are considered "special order items." Allow four to eight weeks for delivery. Delivery times are approximate and additional shipping charges may be applicable. For quotes, please E-mail jsi@jsits.com, Call 88-31-479-4211 .
