Weiss Infrared Thermometer | IR921 | -58 to 750°F / -50 to 400°C
Product Description
The IR921 allows for instantaneous temperature readings without physical contact, making it ideal for measuring moving parts, electrified components, or hard-to-reach surfaces in Dubai and Abu Dhabi’s massive plant rooms. With a wide temperature range of -58°F to 750°F (-50°C to 400°C), it is versatile enough to monitor everything from chilled water lines to hot water boilers and industrial motors.
This handheld device features a built-in laser pointer for precise aiming and a high-contrast backlit LCD screen for easy reading in poorly lit mechanical spaces. Its compact, ergonomic “pistol grip” design ensures comfort during extended use, providing technicians with an essential tool for identifying thermal anomalies and system inefficiencies.
Key Features
- Non-Contact Precision: Measures surface temperatures safely from a distance, protecting the user from heat or rotating equipment.
- Laser Aiming: Features a built-in laser pointer to ensure the user is targeting the exact spot intended for measurement.
- Wide Range: Covers a broad spectrum from sub-zero temperatures to high industrial heat (750°F / 400°C).
- Backlit Display: The digital LCD is easy to read in dark mechanical rooms or under bright direct sunlight in the UAE.
- Data Hold & Auto-Off: Automatically freezes the reading on the screen for easy logging and shuts down to conserve battery life.

Frequently Asked Questions
- Q: Can this be used to measure the temperature of water inside a pipe?
- A: Infrared thermometers measure the surface temperature of the pipe. However, if the pipe is not insulated, the surface temperature is usually a very close indicator of the fluid temperature.
- Q: Is it effective on shiny or polished metals?
- A: Shiny surfaces have low emissivity and can reflect surrounding heat. For the most accurate reading on polished pipes, it is best to place a piece of dark electrical tape on the surface first.
- Q: Why is the 12:1 ratio important?
- A: This means that at a distance of 12 inches, the thermometer is measuring a spot 1 inch in diameter. The further away you are, the larger the area being averaged.
