You can count on our General Tools 4-in-1 Digital Moisture Meter to give you the most accurate readings when it comes to tracking down pesky mold in your home. Our humidity tester provides a moisture level range of 5% - 50% in wood and 1.5% - 33% in building materials, such as concrete and drywall. It has an auto diagnostic check and auto power off after 3 minutes and includes a solid 9-volt battery. The gauge also comes with a lanyard, 2 sets of spare pins, and a user's manual. The sturdy, ergonomic shape and rubber side grips allow for comfort even when using for multiple measurements. Every mold detector has a hold function, saving a read to view later. At General Tools, we offer over 1,000 products to choose from. We're proud to provide merchants, artisans, and DIYers worldwide with a broad range of affordable, specific-purpose mechanical hand tools and precision measuring and inspection gear.

  • HUMIDITY SENSOR: Our combo meter tool can quickly determine what level of remediation is needed to keep your family safe from black mold. High levels of dampness that go untreated are the leading cause of harmful fungus growth in the home.
  • WATER LEAK DETECTOR: Finding the moisture content in your floors, plastered walls, and wood is the first step in early prevention. Continuously check and test suspicious water stains around the house so you can determine if the area is wet or dry.
  • MOISTURE READER: The mold test features 2 dedicated displays, moisture percentage, ambient temperature, and relative humidity. Our mildew scanner includes audible and visual indications of high, medium, and low moisture levels with a °F/°C switch.
  • MOLD TESTER: This tool features both pin-type and pinless (flat pad) surface sensors for an accurate test read on larger areas. Once moisture patches are detected, flip open the cap to expose the pin sensors for more exact content readings.
  • GENERAL TOOLS: We're a recognized leader in designing and developing specialized precision tools dedicated to delivering exceptional customer service. We encourage artisans and DIYers to work smarter, measure better, and repair more productively.
