Last updated 2026-10-02. The editor keeps equipment until it gives trouble, so this list changes slowly.

Current

• Klein Tools ET110 CO Meter: a portable carbon monoxide meter.
• Protmex PT6508 digital psychrometer: a handheld meter that reads temperature, relative humidity, dew point and wet bulb temperature.
• Calculated Industries 7440 AccuMASTER XT: a pin-type moisture meter (the editor uses this model or a nearly identical one).
• TOPDON TC001: a thermal imaging camera that plugs into an Android phone or tablet.
• Fulljion dual-lens borescope (semi-rigid cable, for iPhone/iPad/Samsung): the editor's own note: "ok for the price, but the built-in light can be inadequate in very dark spaces. Might move up a category." Currently unavailable at the retailer as of 2026-10-02.

Past

• Extech MO55 (pin/pinless moisture meter): used previously.
• General Tools Digital Pin/Pinless Moisture Meter: used previously.

Considering

Items here are gear the editor is looking at but has not used, so they carry no opinion from us. Information as of 2026-10-02.

• FLIR ONE Pro (Android, USB-C): a plug-in thermal camera for Android phones. The editor mainly uses Android, and FLIR's other plug-in models are for iPhone. Check FLIR's device compatibility page and current availability before buying.
• FLIR C5: a standalone handheld thermal camera that does not depend on which phone you have. Listed by Bob Vila among thermal cameras worth considering.
