Thermometers/Hygrometers (Product Type: Radiation thermometer)
Thermometers and hygrometers are measuring equipment used to measure temperature and humidity. Depending on the product, they can measure indoor temperature and humidity, surface temperature of objects, temperature of liquids, and the like. Thermo‑hygrometers, which can measure temperature and humidity at the same time, come in 2 types: analog and digital. Bimetal thermometers are products that have 2 strips of metal with different thermal expansion coefficients bonded to sense temperature by the expansion of the metals. The structure is simple, so maintenance is easy, and durability is high, so they are often used for industrial purposes. Radiation thermometers can measure without contacting the object to measure by radiating infrared rays. Remote thermometers measure temperature of distant objects, and analog and digital types can be selected. The temperature range that can be measured is determined by the measuring equipment, so the product must be selected according to its purpose.
