Frequently Asked Questions
Q
What detection principles does the XM314 portable gas detector support?
The XM314 supports four detection principles: Catalytic, Electrochemical, Infrared, and PID. This allows it to detect a wide range of flammable and toxic gases across various industrial environments.
Q
What is the battery life of the XM314 gas detector?
The XM314 is powered by a 3.6V lithium battery with a capacity of 2400mAh. Under normal temperature conditions, the battery life is ≥10 hours, ensuring reliable operation throughout a full work shift.
Q
What is the IP rating and operating temperature range of the XM314?
The XM314 carries an IP67 protection rating, meaning it is fully dust-tight and can withstand temporary immersion in water. It operates reliably across a wide temperature range of -40°C to 60°C, making it suitable for harsh industrial environments.
Q
What alarm types are available on the XM314?
The XM314 features three types of alarms: audible alarm, LED light alarm, and vibration alarm. The sound intensity reaches ≥90dB at 0.3m, ensuring alerts are clearly noticeable even in noisy industrial settings.
Q
What is the difference between the XM314, XM314CGT, and XM314BCGT models?
All three models support 4 sensors. The XM314 uses diffusion sampling without 4G, GPS, or gyroscope. The XM314CGT adds diffusion sampling plus 4G, GPS, and gyroscope features. The XM314BCGT uses pump-suction sampling and also includes 4G, GPS, and gyroscope capabilities.
Q
What certifications does the XM314 gas detector hold?
The XM314 holds the explosion-proof certification Ex db ia IIC T4 Ga and metrological certification CPA. It complies with multiple executive standards including GB15322.3-2019, GB3836.1-2021, GB3836.2-2021, GB3836.4-2021, JJF1364-2012, JJF1368-2012, and JJF1421-2013.
