TUNI is the new generation of rechargeable and combustible gas detector from mPower. It can detect various combustible gases such as methane, ethane, propane, and hydrogen. To ensure the compliance of combustible gas detection, an oxygen sensor can be selected simultaneously to guarantee the accuracy of on-site combustible gas detection. Mengpu'an energy control technology ensures that it can work continuously for 24 hours after a single charge. TUNI is designed to be lightweight, compact and portable, with a protection level of up to IP68, which is suitable for any harsh working environment. The sturdy and durable design is simple to operate, providing effective personal safety protection for on-site workers and can be applied in industries such as chemical engineering, emergency rescue, industrial safety, and petroleum and petrochemicals.
