Light MetersDecreased radiant power related to the degradation of UV lamps, light guides and reflectors results in declinesin process efficiency or incomplete curing of UV light curing products. Loctite® ZETA® Light Meters are used tocheck the intensity of ultraviolet light emitted from a light source. These units are useful for quality measures,maintenance, and troubleshooting of ultraviolet emitting light sources. Selection of a Loctite® ZETA® LightMeter is based on the type of light source that is required to be measured.LIGHT CURE Light MetersLOCTITE ® ZETA ® 7011-A DOSIMETER-RADIOMETER Item Number: 98086LOCTITE ® ZETA ® 7011-V DOSIMETER-RADIOMETER Item Number: 98089The Loctite® ZETA® 7011-A and 7011-V Dosimeter-Radiometers are self-contained, electro-optic metersthat measure and display total energy (J/cm 2 ) and irradiance (W/cm 2 ). They are designed to withstandthe extremes of UV light and high temperature that are part of the UV curing environment. Thecarefully designed optical sensing system measures only certain wavelengths, rejecting those that arenot relevant to the process. The output of the sensing system is converted to digital form and displays aliquid crystal readout. The Loctite® ZETA® 7011-A measures across the ultraviolet spectrum from 320 to400 nanometers (UVA region). The Loctite® ZETA® 7011-V measures across the ultraviolet spectrum from350 to 500 nanometers (UVV region). These units are designed to monitor the performanceof a light curing system.Features:• Measures energy and irradiance lampperformance to determine lamp efficiency• Establishes energy and irradiance level forproper curing when implementing a new process• Calibration is required only once per year• Meets ISO-9000 requirements by providinga device that will allow for recordingof lamp performance data• Dual display of energy and irradianceallows for convenient, same screen viewing• Centrally located sensor allows for easy alignment• Calibration is traceable to theNational Institute of StandardTechnology (NIST)OperatingTemperatureTheory of OperationAn operator will turn the radiometeron, reset the unit, and place the eyeof the unit under the light source forno more than 5 seconds. The readingwill be displayed on the liquidcrystal readout.TECHNICAL SPECIFICATIONS0°C to 75°C internal temperatureNote: tolerates much higher external temperatures for short periods;audible alarm indicates when temperature is too high.5 minutes (if no buttons are pressed)4 digit LCDAutomatic Shut-offDisplayMeasured Spectral 98086 – ZETA ® 7011-ARange320 to 400 nmDimensions4" L x 4" W x 0.52" DWeight 8.6 oz.
