The Drager Polytron IR is an explosion-proof infrared Gas Detector for continuous monitoring of combustible gases and vapors. With its stainless steel body and drift free optics this Draeger Gas Detector is built for harsh offshore environments.
Features
Body of SS 316 stainless steel
Accessories bump test adapter/flow cell
Heated optics
Connector for handheld terminal.
Benefits:
Configuration
Flexible is the configurable measuring range for the Drager Polytron IR: Type 334 offers 0 to 20 %LEL and up to 100 %LEL, alternatively 0 to 100 %v/v for methane. For the type 340, the full scale is configurable from 5 to 100 %LEL. Configuration is menu guided and easy to perform, using a HART handheld terminal.
Calibration
For the easy calibration of the Drager Polytron IR, one gas needs to be selected from an internal list and this gas can differ from the gas to be measured. All data will be converted automatically to the substance to be monitored. So, the intricate use of factors for cross sensitivity calibration is no longer necessary. So for all Draeger Polytron IR Transmitters there is only one calibration gas required, independent of the substance to be monitored.
