In synthetic turf fields, what is used primarily for measuring temperature?

1. Infrared thermometer

2. Digital gauge

3. Temperature strips

4. Clegg hammer

The correct answer is: Infrared thermometer

The primary tool used for measuring the temperature of synthetic turf fields is the infrared thermometer. This device works by detecting the infrared radiation emitted by the surface of the turf, allowing for a quick and non-contact measurement of temperature. Infrared thermometers are particularly effective for this purpose because they can provide instantaneous readings without the need to physically touch the surface, which is especially valuable in outdoor environments where surfaces can become hot. Other options, while related to measurements, do not specifically serve the primary function of measuring surface temperature as effectively as the infrared thermometer. Digital gauges can measure a variety of conditions but typically require a contact method that may not be practical for turf surfaces. Temperature strips generally indicate temperature ranges rather than providing precise readings. The Clegg hammer is used to measure surface hardness and impact resilience, making it irrelevant for temperature measurement in synthetic turf.
