Product Description
The Honeywell 00705-A-1735 Model 705 is a specialized sensor for detecting flammable gases in high-temperature environments. With its UL-approved explosion-proof assembly, this sensor is designed for use in hazardous areas. It employs poison-resistant Sieger detectors that provide reliable low-level alarms and stable detection across a wide temperature range.
- High-temperature performance for hazardous locations.
- Poison-resistant detection for consistent reliability.
- Provides mV bridge output for seamless connection with control equipment.
Product Highlights
This sensor is ideal for applications like turbine enclosures and drying ovens. The configurable measuring ranges allow for monitoring from zero to twenty percent LEL or up to one hundred percent LEL, contingent on the connected controller.
