Mechanics, technicians, and maintenance pros, this Extech RPM10 is like having two essential tools in one handy device! It measures RPMs both ways - contact method for direct readings and non-contact using the laser for hard-to-reach spots. But wait, there's more - it also has a built-in infrared thermometer that reads surface temperatures from -4 to 600°F (-20 to 315°C). The laser pointer helps you target exactly what you're measuring. It even calculates linear surface speed from 0.2 to 6560 ft/minute using the included wheels. Whether you're checking motor speeds, bearing temperatures, conveyor belt speeds, or machinery performance, this tool handles it all. It comes with reflective tape for the non-contact measurements, four AA batteries, and a carrying case that keeps everything organized. The data logging feature is super useful for tracking measurements over time. If you're tired of carrying multiple tools or need something versatile for various troubleshooting tasks, the RPM10 delivers professional-grade functionality in one compact package. It's one of those tools that pays for itself quickly by making diagnostics faster and more accurate.
