Sentrac Strix Hydrogen Leak Detectors

High sensitivity
Low maintenance costs
Wide measurement ranges
Fast recovery time

By using diluted hydrogen gas (95 % nitrogen, 5 % hydrogen), minute leaks can be detected.
Using inexpensive general industrial gas (95 % nitrogen, 5 % hydrogen) as a tracer gas and a sensor that does not react to gases other than hydrogen gas realizes highly sensitive measurement.
Even immediately after detecting a large leak, sensitive measurement can be made immediately.

Features / Functions

Features of diluted hydrogen gas

Hydrogen gas is not easily affected by the atmosphere because it is present at only 0.5 ppm in the air.
It is cheaper than helium gas.
A mixture of 5 % hydrogen and 95 % nitrogen is not flammable.
Since it is not a natural resource, a stable supply is possible.

Features of the product

It does not react to gases other than hydrogen, so it is not affected by other gases in the measurement environment.
The sensor at the tip of the probe reacts to hydrogen in a short time.
Use the OLED on the hand probe to check the leak and other information without having to check the main unit.
Wide measurement range for large and small leaks.
It will recover quickly even after detecting a large leak.
The portable model does not require a power supply and can be used in the field.
Can be used for leak testing not only in manual operation but also in automated systems.
