Natural Gas Detector vs Propane Detector: Why Placement Decides
Most consumer gas detectors sense both natural gas and propane. What separates the two products is mounting height: high for methane, low for propane.

Can a Moisture Meter Detect Mold?
No. It detects the water mold needs. High readings say where mold could be, not where it is.

Why Moisture Meter Readings Vary by Material
The meter measures electricity, not water. Every material turns water into a different electrical signal.

What Makes a Good Thermal Image for Building Inspection?
Right conditions, locked span, square-on framing and a visible reference. The camera is the easy part.
Read Article→Why Thermal Images Change With Weather Conditions
Sun, wind, rain and the inside-outside difference all rewrite what a wall looks like in infrared.
Read Article→Can Thermal Imaging Find Water Leaks?
Often, because wet materials evaporate and cool. But a cold patch needs a moisture meter to prove it.
Read Article→Can a Thermal Camera See Through Walls?
No. It sees the wall's surface. But what is behind the wall changes that surface, and that is the trick.
