SENSYX

Handheld detection instruments

Sense the unseen.Then point at it.

Most handheld leak detectors give you a rising beep and nothing else — no sense of how close you are, no way to tell a real leak from sensor drift. Every SENSYX instrument shows leak intensity in ppm on a color screen as you sweep, so you can pinpoint a leak instead of guessing at it.

SENSYX handheld gas leak detector with flexible gooseneck probe

The range

Three instruments, one readout

Same color ppm display, same 14-inch gooseneck, same USB-C battery. What changes is which gases the sensor answers to.

Why these and not the other ones

Built around the two things that actually slow you down

Reaching the joint, and knowing whether the reading means anything.

14 in

Gooseneck that reaches

355 mm of flexible stainless probe holds its shape where you bend it — behind the condenser, under the dash, above the line set.

ppm

A number, not a noise

The color screen shows intensity as you move. Back off until it settles, press ZERO, move in again — that is how you narrow down to the source.

2500 mAh

USB-C, no disposables

Rechargeable lithium battery and a USB-C port. No alkaline cells to carry, and no consumable sensor tip to replace.

JP

Japan-made sensor
