The MUYA WT8801 is a rugged, industrial-grade combustible gas monitor suited to petroleum, chemical, and pharmaceutical work environments. It measures 0-100% LEL with 0.1 resolution and better than +/-5% full-scale accuracy, responding in under 30 seconds, and raises the alarm through combined sound, light, and vibration alerts. Its color-screen interface can log up to 120,000 readings and runs 8+ hours on a rechargeable lithium battery inside a dust- and explosion-resistant housing.
