    • Description

  • UNIVERSAL LIGHT MONITOR & DATA LOGGER Type LSE774 -------------------------------------------------------------------------------- Replaces 4 separate instruments Thermal Radiation (IR) Ultra Violet (UV) level Visible Light (Lux or Foot-candles) Temperature (¡ãC or ¡ãF) Sized like a small mobile phone Easy one handed operation Large, easy to read display Maximum & minimum with time Optional data logging Thermal Radiation (IR) The measurement of thermal radiation (shown as W/M2 or btu/hour/ft2) allows the user to estimate how much solar heat is coming through windows, check the performance of heat reflecting films, measure the heating effect of lamps on objects etc Visible Light The amount of visible light is important, not only to check illumination in work areas, galleries etc but also to control damage to light sensitive objects that is also caused by normal light. Measurements can be displayed as Lux or Foot-candles. Ultraviolet (UV) For many years it has been recognised that one of the major causes of damage to museum objects and other sensitive objects, soft furnishings etc is the fading and rotting effect of light on the object. The most damaging part of the illumination is its ultraviolet content. Data Logging The optional data-logging function enables over 10,000 readings of all four parameters to be automatically taken at selectable intervals (every 10 seconds to 1 hour). The saved data can then be transferred to a computer by a wireless infra-red link (IrDA compatible). Many modern computers have an infra-red interface built in; for those that do not, adapters are available. When logging data the 774 can be turned off to save power and the built in clock will turn the unit on whenever a reading needs to be taken, this enables a 774 to be left taking readings for months at a time. Software is provided to display the measurements and save the logged data in CSV format that can be accessed and displayed by many programs (e.g. Microsoft Excel). SPECIFICATIONS Visible wavelength range 400-700nM (CIE response). No correction required for different light sources. Visible power range 0.1 - 200,000 Lux (0.1 - 20,000 Foot-candles) UV wavelength range 300 - 400 nM UV power range 2 - 50,000 mW/M2 UV proportion range 0 - 10,000 mW/Lumen Thermal radiation sensor Bismuth/Antimony thermopile with KBr window IR/Thermal wavelength range 350nM - ~40¦ÌM Thermal radiation range 0-1000 W/M2 Display resolution Lux: 0.1 up to 100 then 1 Foot-candles: 0.1 up to 100 then 1 UV: 0.1 up to 100 then 1 Proportion of UV: 1 mW/Lumen Temperature: 0.1¡ãC or ¡ãFIR: 0.1 up to 100 then 1 Accuracy Visible: 5% ¡À1 displayed digit IR: 5% ¡À10W/M2 UV: 15% ¡À1 displayed digit Temperature: ¡À0.5¡ãC (¡À0.9¡ãF) Angular response (Light, UV & IR) Cosine Readout 8 line graphical Liquid Crystal Display with automatic backlight Data logging time intervals(Time till full) 10 seconds (30 hours), 1 minute (7? days) , 10 minutes (75 days),1 hour (454 days) Data logging storage capacity 10,900 readings of all 4 parameters Computer Interface IrDA compatible wireless infra-red link.
