RBB methanol concentration Alarm Kaifeng, Luoyang, sensor or transmission line failure detection and fault alarm the concentration alarm status can be automatically stored, using the main equipment dual power works, to ensure the continuity of the work. The machine work status is stable and reliable, low power consumption. The methanol gas alarm of fixed and portable methanol alarm, handheld leak detector methanol. RBB Alarm methanol concentration, methanol is a colorless, transparent, flammable, toxic volatile liquid at room temperature metal except corrosive lead, aluminum), slight odor of alcohol vapor and air mixture explosion limit 6 ~ 36.5% {volume ratio}, when reached methanol gas explosion limit concentration of 1/4 of the gas alarm controller outputs a corresponding alarm signal and control signal, the linkage solenoid valve or an exhaust fan to prevent gas leakage after accidents. RBB are methanol concentration Alarm features: 1. imports sensor high precision detection accuracy 3 anti-poisoning, stable performance 4. probe explosion-proof structure design suitable for factories and other kinds of dangerous places, high degree of protection, dustproof, waterproof corrosion resistance can be strong measuring range, able to work in an acidic environment. 6 small size, easy to carry, methanol detector main technical indicators of long service life. detection principle: catalytic combustion. sampling methods: diffusion detect gas: methanol gas 4. :0-100% LEL 5. precision: ± 5% F?
