My Real-World Test of Klein’s 69140 Pipe Clamp
I’ve been in the HVAC trade for over a decade, and I’ve burned through my share of pipe clamps and thermometers. When Klein released their 69140, I was skeptical-another tool promising accuracy and durability. But after six months of daily use on residential and light commercial jobs, this thing has earned a permanent spot in my bag. The K-type probe gives me reliable readings on refrigerant lines from 1/8″ to 2″, and the pipe clamp actually stays put, even on sweaty lines. No more holding probes in place while juggling manifold gauges. What surprised me most? The display remains readable in direct sunlight, and the auto-off function has saved my batteries more times than I’ll admit. It’s not perfect, but it does what I need without the headaches.
