1/2 Infrared Temperature Sensors DATASHEET Product Overview The DX501-RS features: • Handheld Precision IR Thermometer • High Accuracy • High Speed • NIST Traceable • Interchangeability ±1% • Resolution 0,1°C • Repeatability 0,1°C • Remote Sensor Technical Data Temperature Range Operating Temperature Calibration Requirement Minimum Spot size Response time Spectral Response °F/°C Conversion Linearity Error Emissivity Adjustment Automatic Emissivity Compensation System Remote Sensor Emissivity Error ± 1% maximum of difference between target temperature and instrument temperature when touching, for emissivity of 0,8 to 1,0 Automatic Emissivity Compensation System The DX-Series is an entirely different type of instrument than conventional temperature measuring devices. Designed specifically for the highest possible accuracy, it is the only infrared instrument whick can be certified with NIST-traceable accuracy on real surfaces of unknown emissivity, while remaining completely free of the contact errors and heat sinking errors of contact devices. Recessed cone traps all emitted surface radiation, adn blocks out any radiation from environment Actual measurement area is in the center, well away from the area contacted by the edge of the cone Reflective cone automatically corrects for emissivity variations by creating an actual blackbody at the precise location of measurement Only a thin lip of material actually contacts the target, thus minimizing heat transfer Figure 1. Unique Automatic Emissivity Compensation System (AECS) produces accurate temperatures everywhere the infrared probe is placed by creating in own blackbody The sensing area of the DX Scanner is equipped with a reflective surface to correct for emissivity variations Exergen Global offices: The Netherlands Pastoor Clercxstraat 26 5465 RH Veghel Tel: +31 (0)413 376 599 Fax: +31 (0)413 379 310

2/2 Infrared Temperature Sensors DATASHEET 8 reasons the DX Series of handheld infrared scanners from EXERGEN are Superior to Conventional Devices 1. No emissivity The true emissivity of a surface can never be accurately determined by conventional infrared devices. Without Exergen’s Automatic Emissivity Compensation System, IR devices with a pre-set emissivity setting can only display an approximate temperature over their entire temperature range. The accuracy specifications given by most manufacturers are only for a “blackbody” calibration and do not hold outside laboratory conditions. Blackbody...
