Titan Fixed Benzene Detector

The world’s first continuous, benzene-specific monitor!

Set to change the game in refinery applications, Titan is the first truly selective fixed benzene monitor on the market.

Titan is a fixed, continuous, real-time, benzene-specific monitor designed for petrochemical environments, providing the ultimate device for plant and worker safety.

The instrument is wall-mounted with a dynamic detection range or 0 – 20 ppm with 0.1 ppm sensitivity to benzene. Titan samples gas from the environment once per minute and within just 60 seconds an accurate benzene measurement is displayed.

Titan provides an immediate warning alarm system with two operator configurable levels, ensuring workers are kept safe and protected to the standards required on site. The instrument incorporates two relay outputs allowing you to install your own required alarm system.

Titan’s continuous, real-time measurement allows trends to be monitored over time, and communicated via 4-20 mA or RS485. Data is stored internally and can be downloaded remotely for analysis.

Designed to be easily installed and serviced, the modular design allows the Ex d case to be installed well in advance of commissioning. The internal service module can be removed and replaced as a remotely serviceable plug and play cartridge.

Titan incorporates Ion Science patented photoionisation detection (PID) sensor technology with proven resistance to humidity and contamination, ensuring optimal performance, however challenging your environment
