The PyroUSB is an industrial infrared temperature sensor with a 2-wire 4-20 mA output and USB interface.

A choice of 3 types is available:
- General purpose (8-14 µm) for measuring non-reflective non-metals from -40°C to 1000°C
- Short wavelength (2.2 µm) for measuring bare iron and steel surfaces from 45°C to 2000°C
- 5 µm for measuring glass surface temperature with minimal reflectivity

• Two-wire, loop-powered 4-20 mA output
• Compact housing - only 61 mm long including cable glands
• Temperature ranges from -40°C to 2000°C
• Fully configurable via USB using Calex or third-party Modbus software.
• Removable USB cable included
• Peak and valley hold mode for measuring objects on conveyors
• Stainless steel housing, sealed to IP65
• Quick and easy installation
