Description
Technical data
Description
The fast and versatile infrared thermometer with 2-point laser marking and 30:1 optics. The surface temperature, also of smaller objects, can be measured at a safe distance. The diameter of the measurement spot is only 36 mm at a distance of 1 m. Possibility of connecting external temperature probes. This universal infrared thermometer is designed to perform fast and accurate surface temperature measurements in the HVAC area and industry. At a distance of 1 m the point diameter is only 3.6 cm. From a secure distance even smaller, difficult to access or dangerous targets can be measured without any problems. The new high resolution processor enables measurement results of unbelievable accuracy. And due to the min./max. function you can define your temperature limit values according to your needs. To control the limits with the help of an audible and visual alarm has never been easier.
  • Even more accurate measurements thanks to the new processor
  • Improved control of limit values due to min./max. function
  • Adjustable emission factor 0.1 to 1.0
  • 30:1 optics for measuring temperature at a distance, even on small objects
  • 2 laser beams for marking the measurement spot
  • Display of current value and Hold value
  • Emissivity determination with external temperature probe
  • Audible and optical alarm when limit values are exceeded
  • Fast measurement value recording at two measurements per second
  • Display illumination
  • Contact measurement with connectable probe
  • Input of upper and lower limit value
