Non-Invasive Moisture Detection: Protect Your Property from Hidden Water Damage

The Klein Tools ET140 Pinless Moisture Meter is an essential diagnostic tool for homeowners, contractors, and inspectors looking to identify hidden water issues without damaging surfaces. Utilizing advanced Electromagnetic Field (EMF) technology, this meter provides non-destructive moisture detection up to 0.75 inches deep. It is perfectly calibrated for testing drywall, masonry, hardwood, and softwood, making it ideal for pinpointing leaks behind walls, assessing subfloor conditions before flooring installation, or checking lumber for woodworking projects. The intuitive mode button allows you to switch between materials instantly, ensuring accurate relative moisture readings every time.

Engineered for clarity and durability, the ET140 features a high-visibility, reverse-contrast display paired with a nine-segment LED bar graph for quick visual references. An integrated audible alert provides immediate feedback in hard-to-reach areas where the screen might not be visible. Built to handle the rigors of the jobsite, this meter is constructed from rugged ABS plastic and is rated to withstand a 6.6-foot drop. With convenient functions like data hold, auto-power off to conserve battery life, and a low battery indicator, the ET140 is a reliable partner for preventing mold and structural damage caused by undetected moisture.

For work or casual wear, this polo is a great choice.
Material Type: Recycled Polyester, Color: Port Stripe, Size: X-Large
I really like this polo. I've been wearing it once a week or every other week since November. Its very comfortable and breathable. This polo feels like it should last a while. The fit is good. I typcally wear XL and this XL fits great. I've pruchased it in both burgundy and black so far. I definitely recommend this shirt. For work or casual wear, this will look good.

Great value: These are my go-to work from home shirt
Material Type: Recycled Polyester, Color: Blue, Size: X-Large
I’ve been pleasantly surprised by these shirts and wear them weekly for Zoom calls, since I’m still working from home these days. I figured at the price point it was worth trying them out, and now I’ve bought several in different colors. They aren’t super soft, but they are comfy and look nice. I’m 6’1” ~220 pounds, and the XL slim fit still has plenty of room. I imagine the regular cut is incredibly boxy and oversized. The difference between polyester vs recycled polyester is inconsequential. I typically buy expensive golf shirts, and these definitely aren’t as nice. They are a fraction of the cost though and a great “beater” work shirt / hang out shirt. It’s nice wearing something that looks and feels decent, but if something happens to it, you can toss and it and pick up another for the cost of a chipotle burrito.

Great price, not great quality
Material Type: Recycled Polyester, Color: Black, Size: Small
Simple, straight forward all black polo. I am a size medium woman (with some room since I don't like form-fitting) and bought a men's small. Fits perfectly for my frame. Long enough to tuck in for my part-time extra weekend job uniform. Also suitable for the golf course. A little thin, and if you hold it up to light you can sort of see through it. *Not* flowy, soft and smooth fabric like a rash guard/sun shirt - more structured than that. But it's cool and does the job for the price under $10.
