TopTes PT-990 Gas Leak Detector – 11-inch Probe, 0–10,000 ppm, Data Logging & 3 Alarms

Enhance safety with TopTes PT-990 Gas Leak Detector

Designed for on-site confidence, the PT-990 is a rechargeable gas leak detector that blends a rugged form factor with precise sensing. Featuring an 11-inch flexible probe, it lets you look into crawl spaces, ceilings, and machine rooms without moving the detector itself. The integrated Figaro sensor for combustible gases covers a broad range from 0 to 10,000 ppm, translating subtle hints of a leak into clear data that you can act on.

Fast, precise readings that matter

Response time is a key advantage. The PT-990 delivers instant feedback in as little as 0.5 seconds, and the 0–10,000 ppm range enables a meaningful view of concentration levels as you inspect. A built-in fan helps draw in ambient air, improving sampling and accuracy in real-world environments.

Data logging, control, and flexible operation

Beyond simple alerts, this detector records critical details such as the exact alarm time and the ppm reading when an alert triggers. A one-button quick mute and manual calibration offer practical control during busy inspections. The unit provides both real-time PPM and a dynamic trend line to help you see how readings evolve over time.

Clear, customizable alarms

Three independent alert channels let you tailor your warning system. A 90 dB audible buzzer, visible indicator lights, and optional vibration alerts can be enabled or disabled to match your environment, from quiet offices to noisy industrial floors.

Built for real-world use

The PT-990 ships with an 11-inch flexible gooseneck for reaching tight corners, a long-lasting 4000 mAh battery (nine hours or more per charge), and USB-C charging with a dustproof cover. A vibrant TFT display with adjustable brightness keeps readings legible in bright sun or dim workspaces, and auto sleep helps conserve energy when idle.

What you get

Inside the box you will find the PT-990 detector, USB-C charging cable, a zippered storage case, and a multilingual user manual all designed for quick setup and immediate use.
