9000 Series

This portable multi-gas monitor is equipped with a strong sample pump and various sensors to enable simultaneous detection of multiple gases. Its explosion-proof, durable design and lineup of detectable gases make this versatile device ideal for use in a wide array of applications in a variety of settings, such as the petrochemical, marine, automotive and fumigation industries.

9000 Series

Feature01

Detect multiple gases at the same time

Select the gases you want to detect for use in a wide range of applications. The GX-9000 detects 4 standard gases (O₂, H₂S, CO and hydrocarbons), and even up to a total of 6 different gases (including VOCs) simultaneously when used with up to 2 additional sensors (some 1000 sensor combinations in total). The SC-9000 allows for simultaneous detection of up to 3 out of 15 different toxic gases (over 300 sensor combinations in total).

Feature02

MED-approved

Both the GX-9000 and GX-9000H are MED-approved devices. Designed for use in the marine industry, both models are adapted to meet the needs of a range of settings and applications in the marine industry.

Feature03

Manage data easily from your smartphone

Equipped with BLE (Bluetooth Low Energy), allowing for fast, wireless transmission of data. Download the free RK Link app to check data easily on your smartphone or tablet.

Feature04

Equipped with the most powerful built-in pump of any portable gas detector

Use with a sampling tube attachment of up to 45m to measure various gas levels within tanks or during gas freeing.
