Plain-language explanations of the measurements, sensors and numbers behind environmental monitoring.

Pins measure at the point they pierce; pads scan without marking. Most inspectors carry both.

Right conditions, locked span, square-on framing and a visible reference. The camera is the easy part.

Sun, wind, rain and the inside-outside difference all rewrite what a wall looks like in infrared.

Often, because wet materials evaporate and cool. But a cold patch needs a moisture meter to prove it.

No. It sees the wall's surface. But what is behind the wall changes that surface, and that is the trick.

One pixel versus thousands. A spot thermometer reads a temperature; a camera shows where the temperature is.

Polished metal is an infrared mirror. The camera sees the room, the lights and you, not the metal.

How well a surface radiates heat compared with a perfect emitter. Set it wrong and the temperature is wrong.

The smallest temperature difference the camera can distinguish from noise. Lower is better; under 50 mK is good.

The native detector array is the real number. Everything else is upscaling or the visible camera.

Everything warm glows in infrared. The camera has a sensor that sees that glow and a lens that lets it through.

Measures how much light lands on a surface. Useful for workplaces, plants, photography and checking a "bright" room.
