Frequently Asked Questions (FAQ)
What gas detection principles are utilized in the XM314 series?
The XM314 gas detector supports multiple advanced sensing principles including Catalytic, Electrochemical, Infrared, and Photoionization Detection (PID), allowing high-accuracy monitoring of both flammable and toxic gases.
What type of alarm system is integrated for safety warnings?
It features a triple-layer alarm warning system: a loud audible alarm (≥90dB at 0.3 meters), bright LED light flashing alerts, and a physical vibration alarm to guarantee operators are alerted in noisy environments.
What is the battery capacity and runtime of the XM314?
The device is powered by a 3.6V 2400mAh rechargeable lithium battery with low power consumption (≤1W), delivering a continuous operating battery life of ≥10 hours at normal ambient temperatures.
What environmental and explosion-proof ratings does the device hold?
The unit carries an IP67 water and dust ingress protection grade, Ex db ia IIC T4 Ga explosion-proof certification, and CPA metrological verification, operating effectively in temperatures ranging from -40°C to 60°C.
What self-diagnostic capabilities does the unit have?
The instrument automatically performs health diagnostics including low battery, calibration reminders, sensor lifespan, sensor failure alerts, calibration lock, memory status, and pump blockage/leakage monitoring.
What is the difference between standard and "CGT" or "BCGT" models?
Models designated with "CGT" include advanced wireless and tracking modules (4G connectivity, GPS positioning, and Gyroscope motion detection), while "BCGT" models integrate pump-suction sampling alongside these features.
