Single point Chemcasette tape-based gas detector - SPM Flex

The Chemcassette technology

Gases sampled by a sampling pump are sent to a strip of chemically impregnated paper. In reaction with the target gas, the paper strip will change color to be analyzed by a very powerful optical system. It is a very precise method for analyzing the most sensitive toxic gases, such as hydrides, mineral acids, oxidants or amines.

Optical toxic gas analysis system SPM FLEX

• Chemcassette patented technology insensitive to interference
• Integrated sampling pump - Rapid response for target gas detection
• Sensitivity to gas (in ppb) with physical proof
• Interchangeability of Chemcassettes
• Reduced maintenance and no dynamic calibration
• Digital concentration display
• Ethernet computer communication (MODBUS TCP / IP)
• USB port for data recovery
• More than 50 available gases (toxic, corrosive or pyrophoric)

A configuration for each application

The SPM FLEX toxic gas optical analysis system has many options ensuring reliable detection for each particular application:

• Fixed or portable version on battery
• The sampling pump capacity can go up to 30 meters for certain gases
• Possibility of adding a remote display and a remote alarm acknowledgment.
