IRtech Radiamatic IR20 LS series is an advanced process infrared thermometer composed of a measuring head and separate electronics. The control unit makes start-up and maintenance easy.

All settings including emissivity are available via the panel and can be changed with the integrated keyboard.

The double laser pointer facilitates the alignment of the pyrometer by indicating the actual measurement area. The laser can be turned on directly from the keyboard or remotely with the digital interface.

The temperature of the measuring head is monitored and the laser is automatically switched off above 50°C.

The modular expansion slot will allow you to add expansion cards such as USB, RS232, RS485, Profibus, Can, Ethernet digital interfaces and the card with two alarm relays. This allows you to avoid installing an additional indicator.

The advanced signal processor allows the use of functions such as averaging, peak picker, remote emissivity programming, ambient temperature compensation and many other functions.

Analog input: external emissivity, ambient temperature compensation, trigger

Including remote control unit with display and keyboard.
