TEL-FAST thermometers are hand-held, battery-operated devices that safely and accurately measure temperature using non-contact infrared technology. Infrared sensors consist of optics, detector, display, and output. Special optics gather infrared energy from a target and focus this energy onto a custom detector. The detector converts the infrared energy into an electrical signal proportionate to the temperature of the target surface being measured and is displayed as a digital temperature measurement in °F or °C within milliseconds. Tel-Fast thermometers are ideal for food preparation, automotive, science, electronics, plant maintenance, construction, and HVAC markets.
Rugged plastic design and one button operation combine for ease of use. Simply point the unit at the desired target and hold the "on" button for the temperature to display.
Optional laser sighting feature makes aiming very precise.
One special feature of the QT418LD is a Type K thermocouple port, which will accept the 50426-K thermocouple. This item is designed for use in insertion/immersion applications for a quick response, or for measuring high temperatures. Other Type K probes are also available, please contact the factory for price information.
