Features
- The twin laser sight for the IT-500 Series non-contact thermometers allows the user to see that the thermometer is focused on the target.
- The Models IT-550F and IT-550L have a target area of Ø 24 and a range of 1000 mm. The maximum target and range of these models is Ø 80/2000mm.
- The IT-550S has a measurement spot size of Ø 2.5mm and a range of 73mm.
- The IT-550 Series thermometers are splash-resistant. The thermometers can be safely used with wet hands, humid environments and rain. IECIP54 rating (splash resistant): no adverse effects resulting from exposure to splashed water from any direction.
- The IT-550 Series thermometers are equipped with a data hold function, and have both digital and analog outputs for connection to computers and printers for flexible data manipulation and output.
- Data printout is possible by connecting the expansion kit to the IT-550F model.
- The IT-550L and IT-550S units have an analog output that can be used to record data on a data logger or to process data using a personal computer. The expansion kit is sold separately.
