America intrinsic OLCT IR infrared fixed gas detectioninstrument
OLCT IR infrared fixed gas detection instrument
The offshore platform, petroleum chemical industry,marine equipment and waste water treatment places the work environment is usually considered the most severe,infrared technology often become the only solution.OLCT IR is a can adapt to the harsh environment, andfire and gas detection instrument with high efficiency.
Leading technology recognized
"Zero maintenance" efficiency
• OLCT IR semiconductor electronic componentsguarantees very accurate and stable.
• cost greatly reduced:
Initial calibration, instrument life-long stability
Almost no maintenance
The false alarm processing
• misinformation often bring economic losses, OLCT IR can cause discrimination and neglect the external factorsof false positives.
