Fixed Benzene Specific Gas Monitor: Titan

The fixed benzene specific gas detector possesses a dynamic detection range or 0–20 ppm with 0.1 ppm sensitivity to benzene. The Titan can be wall-mounted and it samples gas from the atmosphere once per minute, offering a precise and accurate benzene measurement in under a minute.

This fixed benzene specific gas monitor’s immediate warning alarm system offers two operator configurable levels, safeguarding your workforce ensuring they are safe and well protected according to on-site regulations.


Titan fixed benzene specific gas monitor features continuous, real-time measurement that facilitates the constant monitoring of trends that are communicated via 4-20 mA or RS485. Data is internally stored and is always available for analysis with the remote download feature.

Developed to be easily installed and serviced, the modular design enables installation of the Ex d case well in advance of commissioning. Removal and replacement of the internal service module is possible due to the remotely serviceable plug and play cartridge feature.
