TopTes PT-990 Rechargeable Gas Leak Detector — 0-10,000 ppm, 11" Probe, Data Logging, 3 Alarms

Overview

The TopTes PT-990 is a rechargeable gas leak detector designed for home use, workshops, and industrial spaces. It pairs a high-quality Figaro sensor with an 11-inch flexible gooseneck to sample air precisely where you need it. It can detect combustible gases across a broad range from 0 to 10,000 ppm (0% LEL to 20% LEL). An integrated air-flow fan helps bring samples into the sensor for fast, reliable readings, with an exceptional response time as quick as 0.5 seconds.
