Thermal Master P1 Thermal Camera vs Thermal Master Thor002 Thermal Imager

Buy the P1 if you want a tiny plug-in module for phone-based electronics work and already own a good phone. Buy the Thor002 if you want a standalone tool for home inspection, with its own screen, battery and tougher body. The Thor002 has the better sensor (256×192 native, 512×384 enhanced) and a 3.5-inch IPS display, so it reads clearly without a phone. The P1 is lighter and cheaper to own, but its 160×120 detector and phone-dependent app draw the most complaints. Owners of both rate them highly; the Thor002's 4.9 from 83 ratings edges the P1's 4.7 from 301.

• Choose the Thermal Master P1 if you do electronics repair or quick troubleshooting and want a pocket module that plugs into your phone or PC.
• Choose the Thermal Master Thor002 if you inspect houses, HVAC or equipment and want a self-contained camera with its own screen, battery and drop-rated body.
