Introducing the RS PRO RS-8861 infrared (IR) thermometer. This RS PRO infrared temperature detector is a handheld device that can detect the environmental temperature by using a non-contact method of measurement. This instrument also measures surface temperature using an infrared sensor and includes dual laser pointers for better and more accurate targeting. This non-invasive and non-contact method of temperature measurement removes the issue of having to rely on using a physical contact on the item to get a reading from it, making it ideal for use in industrial environments like steelworks, oil and chemical production, environmental testing, gas production industries and much more. This dual laser temperature detector provides fast sampling with high accuracy, making it an incredibly useful and versatile tool across a range of applications.

Infrared thermometers are instruments that measure the surface temperature of an object. They generally use a laser to point at the surface for the reading to be taken, whilst others include a temperature probe that measures the inside temperature of an object. Infrared thermometers are an essential device for individuals who need to measure the temperatures of something without physically touching the item. They can be found in the following areas:

• HVAC


• Industrial processes


• Environmental testing


• Scientific and Educational

Most IR laser thermometers have a measurement error specification, which shows their best accuracy. The surface being measured can also affect accuracy. Reflective objects result in lower measurements than the actual temperature, whilst non-reflective surfaces give a higher measurement. The emissivity of a surface is how effective it is at emitting energy as thermal radiation, as such some IR thermometers have adjustable emissivity settings.

Distance to spot ratio is also essential in providing accurate temperature measurements, if an infrared thermometer is too close to its target area, heat can build up in the device. This can give false readings or damage the temperature sensors
