## Long description

The Thermometer TFA-Dostmann Beam is a handheld infrared thermometer for contact-free surface temperature measurement. It measures temperatures from -38 to 365 °C (-36 to 689 °F), includes a laser pointer for aiming, a rectangular backlit display that shows the current and highest temperature, and runs on a single 1.5 V AAA battery. Its compact dimensions (40 mm × 85 mm × 175 mm) make it easy to hold and operate for a variety of measurement tasks.
Advantages
The device provides fast readings (measuring time approximately 1 second), a clear visual target with the laser pointer, and a backlit display for use in low-light conditions. Accuracy varies by range, typically ±1.5 °C to ±3 °C depending on the measured temperature. The 12:1 distance-to-spot ratio helps determine the measured area at different distances, and the compact form factor supports portable use.
Suitable for
Checking surface temperatures of cooking surfaces and appliances
Quick temperature checks on HVAC components and radiators
Maintenance diagnostics for motors and electrical panels (surface only)
General-purpose surface temperature measurements in workshops and homes

How to use
Aim the laser pointer at the surface to be measured and keep the thermometer within a distance appropriate for the 12:1 distance-to-spot ratio to ensure the target area is within the sensor field. Press the measurement button and read the result on the backlit display; the device updates the current temperature in about one second and also records the highest measured value. Replace the AAA battery when the display indicates low power or readings become unreliable.
Usage recommendations
Allow the instrument and the measured object to acclimatize to the same ambient temperature for the most accurate results. Avoid measuring through glass or transparent surfaces and do not use the device to measure body temperature. For small or distant targets, move closer to ensure the spot size fits the target according to the 12:1 ratio.
