Frequently Asked Questions
Q: What is the measuring range of the LAOLAU GM550 infrared thermometer?
A: The GM550 measures surface temperatures from -50°C to 500°C (-58°F to 932°F), making it versatile for both sub-zero cold environments and high-heat industrial applications.
Q: Does the GM550 infrared thermometer come with batteries?
A: No, batteries are not included. The thermometer requires 2 × AAA batteries, which are available separately. Once installed, the battery life is approximately 12 hours of use.
Q: What does adjustable emissivity mean and why does it matter?
A: Emissivity refers to how efficiently a surface radiates heat. Different materials (e.g., metal, plastic, ceramic) have different emissivity values. The GM550 allows you to adjust the emissivity from 0.1 to 0.99, ensuring accurate readings across a wide variety of surfaces and materials.
Q: Is the LAOLAU GM550 suitable for home use as well as industrial use?
A: Absolutely. While designed with industrial applications in mind, the GM550's ease of use, compact handheld design, and wide temperature range make it equally practical for home tasks such as checking cooking surfaces, appliances, HVAC vents, and more.
