Overview

This sturdy and durable DR70C-O2-25 oxygen detection alarm is a new intelligent high-performance oxygen detection alarm launched by WOST company. The shell is made of high-strength aluminum alloy material, with an overall explosion-proof design, a brand new circuit board, low-power high-performance components, program optimization, and stable performance; Adopting industrial grade sensors imported from Japan, it can resist acid and alkali gas interference and is completely unaffected by CO2, CO, H2S, NOx, and H2; Long service life of 5-10 years or more; The DR70C-O2-50 model has a 10-year lifespan and an accuracy of ± 2FS, with a full range accuracy of ± 1%. Detection range: 0-5% VOL, 25% VOL, 30% VOL, 100% VOL, resolution 0.001% VOL, 0.01% VOL, three wire 4-20mA, RS485 RTU dual signal output. The instrument is compatible with various types of PLC, DCS and other control systems, and can easily complete monitoring, alarm, signal transmission, remote monitoring, and emergency equipment startup. Unique remote control and status detection allow you to easily collect data analysis and activate alarm plans even without being on site. WOST company has launched various sensor optional solutions. For detailed information, please call for consultation.
