Where to Place a Natural Gas Detector (and How High)
Mount a natural gas detector high, within about 12 inches of the ceiling, in the room with the gas appliance, away from the range, vents and windows.

Plain-language explanations of the measurements, sensors and numbers behind environmental monitoring.
What Is True RMS on a Multimeter?
The way a meter calculates AC values. Averaging meters guess a sine wave; True RMS measures what is there.

Gas Detector vs Smoke Detector: What Each One Senses
A smoke detector senses particles from a fire that is already burning. A gas detector senses unburned fuel before it ignites. Neither responds to what the other is built for.

Thermal Camera vs Borescope: Which Inspection Tool Does What?
One finds where to look from outside; the other looks inside. They are a sequence, not a choice.
Read Article→Plug-In vs Battery Gas Detector
For a combustible gas alarm, plug-in with battery backup is the default and usually the right choice. Battery-only gas alarms are rare because the sensor heater drains batteries too fast.
Read Article→Does a Carbon Monoxide Detector Detect Natural Gas?
No. A CO detector cannot sense natural gas, propane or methane, and a smoke detector cannot either. Only a combustible gas sensor responds to a fuel leak.

What Is a Borescope and When Is It Useful?
A camera on a cable that goes where your eyes cannot: cavities, ducts, drains, engines.

A fixed alarm guards a room around the clock; a handheld sniffer finds a leak you already suspect. Buy the alarm first; add the sniffer for specific jobs.
Read Article→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.

A gas leak detector senses unburned fuel before it can ignite; a CO detector senses the poison left by fuel that burned badly. Neither covers the other.

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