4 in 1 Colorful Portable Gas Detector
H2S/O2/CO/ Ex
Diffusion Type | With hose and probe | Multi Gas Clip

Clearance measurement was never this easy and convenient!
ZLT850 4 in 1 portable multi gas detector monitor CO, H2S, O2 and combustible gas simultaneously.
The instrument with large Colorful LCD Display, audio/visual and vibratory indicators, rechargeable battery, and simple use.
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.

• COLOR DISPLAY: Adopt high resolution TFT display, color display speed is faster, contrast and brightness are also greatly improved.

• POLYMER BATTERY: 2500mAh, full charge about 8-12 hours, full charge can be used for about 10-12 hours.

• HIGHLY SENSITIVE SENSORS: Effectively predict dangerous gases, ensure the safety of personnel and property.

• ALARM STATUS: When the concentration of dangerous gas is higher than the minimum alarm value, the detector will immediately sound to remind "Please pay attention to the gas concentration exceeds the limit ", and the alarm will continue until the dangerous gas concentration returns to the lowest value, the alarm will disappear.
