600 Series

Our easy-to-install 600 Series gas detectors have a built-in sensor and offer high performance and functionality at a surprisingly accessible price when compared to other industrial gas detection brands. Our industrial-grade sensors are designed and manufactured in house for reliable performance you can trust.

600 Series

Feature01

3 power supply options (excluding RI-600)

Supports three types of power supply: AC, DC or dry cell battery (excluding RI-600). Dry cell batteries allow for about one year of use in environments without access to a power supply. The battery unit itself is easy to remove, making maintenance a breeze.

Feature02

Gas detection even in remote locations

Equipped with a remote sensor, the 600 Series allows for detection of gas concentrations up to 20 meters away from the main unit. When using sample draw instruments, it takes time for the gas to reach the sensor, leading to delays in detection time. But with our 600 Series remote sensor, the sensor can be placed in the detection area itself, allowing you to obtain accurate measurements in real time.

Feature03

Oxygen sensor with compensation for pressure changes

Our OX-600 oxygen sensor compensates for changes in atmospheric pressure, eliminating issues with inaccurate readings due to fluctuations in pressure often experienced when using traditional oxygen sensors. Get accurate readings regardless of the weather with OX-600.
