The IRtech Radiamatic IR40 series is a Smart 2-wire process infrared thermometer. The instrument is powered by the loop directly on the wires of the 4-20mA analog output which is programmable on the temperature range.

A USB interface is available for direct connection to PC to read data digitally in continuous mode or set parameters. An output is also available to drive an alarm setpoint.

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

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 emissivity can be adjusted directly on the selectors on the rear panel where the removable terminal block is located.
