Frequently Asked Questions
Q
What gases can the XM314 portable multi-gas detector detect?
A
The XM314 is designed to detect both flammable gases and toxic gases. It supports up to 4 sensors simultaneously and uses detection principles including Catalytic, Electrochemical, Infrared, and PID, covering a wide range of hazardous gas types. Please refer to the toxic gas list for detailed gas coverage.
Q
What is the battery life of the XM314, and what type of battery does it use?
A
The XM314 is powered by a lithium battery with a nominal voltage of 3.6V and a capacity of 2400mAh. Under normal temperature conditions and typical usage, the battery life is ≥10 hours, making it suitable for extended field operations.
Q
Is the XM314 suitable for use in explosive or hazardous environments?
A
Yes. The XM314 carries explosion-proof certification of Ex db ia IIC T4 Ga, and meets multiple executive standards including GB3836.1-2021, GB3836.2-2021, and GB3836.4-2021. It is designed and certified for safe use in hazardous explosive atmospheres.
Q
What is the difference between the XM314, XM314CGT, and XM314BCGT models?
A
All three models support 4 sensors. The XM314 is the standard diffusion-type model. The XM314CGT adds 4G connectivity, GPS, and Gyroscope features while retaining the diffusion sampling method. The XM314BCGT upgrades to pump-suction sampling and also includes 4G, GPS, and Gyroscope, making it ideal for confined space and remote monitoring applications.
Q
What self-diagnosis functions does the XM314 support?
A
The XM314 features a comprehensive self-diagnosis system that monitors: low battery status, calibration prompts, sensor life, sensor failures, calibration signal lock, insufficient register memory, air pump blockage, and air pump air leakage. These diagnostics help ensure reliable operation and timely maintenance.
Q
What environmental conditions is the XM314 rated for?
A
The XM314 is built for demanding environments. It carries an IP67 protection rating, operates across a wide temperature range of -40°C to 60°C, handles humidity between 10%~95%RH (non-condensing), and functions within an atmospheric pressure range of 86kPa~106kPa. Its casing uses anti-static TPU and anti-static PC materials for added durability.
