Handheld infrared thermometer Raynger® 3i Plus for high-temperature applications

Raynger® 3i Plus handheld thermometer for flexible monitoring of critical processes and quick verification of fixed sensors (PresseBox) (Berlin, ) Raytek presents a new handheld thermometer series for flexible temperature monitoring in high-temperature industrial applications from 400 to 3,000 °C, for instance in steel production and processing, the chemical and petrochemical industry, as well as heat treatment and power plants. Raynger® 3i Plus 1M and 2M models measure infrared radiation in the shortwave spectrum (1 µm and 1.6 µm) and provide high precision (+/- 0.5%, 1 °C). Thanks to the superior resolution of 250:1, critical plant parts and products can be reliably monitored from longer distances. For exact aiming, the measurement spot is highlighted with two laser beams. Moreover, even red hot objects can now be easily targeted by means of a new "Red Dot" scope sighting function (patent pending). Additionally, the use of a "Red Nose" heat-resistant warning detector and alarm reduces the risk of the sensor overheating, minimizing repair costs while averting costly accidents and ensuring operator safety.

The robust handheld devices withstand drops of 1 m. A powerful firmware supports display, analysis, and trending within the device. Up to 4,900 data points can be recorded. The scope of delivery furthermore includes the Raytek DataTemp® Windows PC software which supports real-time communication and further data processing. In addition to on-board USB and Bluetooth interfaces, a mobile app allows for comfortable data storage and sharing. The display can be set to degrees Celsius or Fahrenheit. The devices are equipped with a Lithium-ion battery that can be easily recharged and enables an operational cycle of 24 hours.
