The S4000TH Intelligent Gas Sensor is a microprocessor-based transmitter designed for use with General Monitors' thin film metal oxide semiconductor (TFMOS) sensors to detect H2S gas. The unit features one person calibration and can virtually self-calibrate by simply activating a magnetic switch and applying gas.

Typical safety standards require that a gas detection unit give warnings at 10 – 20% of the LEL. Do not confuse the alarm level with the volume of gas required to reach the LEL. For example: Methane has an LEL of 5% by volume in air. For a gas detector to give an alarm at 10% of the LEL, it must trigger when it detects 0.5% by volume.

BH-4s portable multi-gas detector could detect combustible gas, O2 and other two types toxic gases continuously and simultaneously. It is widely used in the area where explosion-proof is required or toxic gas leaks, like underground channels or mining industry, so as to protect the workers' life and avoid damage on the relevant equipments.
