  • Official site

It can measure over a wide range! Linear scan type infrared thermometer.

The LTH1 series linear sensor radiation thermometer is a radiometric thermometer that can simultaneously measure multiple points along a straight line. It can measure at a maximum speed of 1 kHz, allowing for measurements of moving objects without missing them! It is possible to distribute 46 sensors across up to 8 sectors, and since it can output analog signals for each sector, it can be freely utilized on production lines. Additionally, by using the dedicated PC software LTMS, it is possible to process and display temperature data as images, similar to thermography. *Custom orders and modifications are available even for just one unit! Please feel free to contact us. We have numerous achievements in measuring the temperatures of randomly flowing workpieces on conveyors, temperature distributions of various workpieces such as steel plates and films, and sealing temperatures of bag-shaped packages for food products. 【Features】 ■ Simultaneous measurement of multiple points along a straight line ■ High-speed scanning at a maximum of 1 kHz ■ Relatively inexpensive compared to thermography ■ Outputs analog signals for 8 points, making it usable for controlling production equipment ■ Measurement through windows is also possible ■ The included PC software can save all pixel sampling data ■ Continuous measurement of upper limits, lower limits, average values, etc. ★ Please apply for a free demo unit using the link below.
