OLLI is a multiple gas pressure and measurement detector.

Designed with today's conditions and technological considerations in mind, OLLİ is a functional gas detector with a working area and ergonomic appearance as well as technical features.


OLLI can edit ppm/lel/volume measurements regularly in the same menu.

You can measure different values ​​such as CH4/CO/CO2/O2/H2S at the same time.

OLLI is the only system where you can perform pressure testing, stabilization and reporting up to 1 bar at the same time.

Thanks to its patented filter technology, OLLI absorbs harmful substances such as dust, moisture, etc. that can enter the device 2 times faster than other devices, ensuring a longer-lasting and healthy operation of the device. 

With its jack problem options, it is the only system where you can solve the problem without going to technical service in case of a possible problem, malfunction or replacement.
