K400 Four-in-One Gas Detector adopts imported sensor and micro
control technology and has fast response, high measurement
accuracy, good stability and reproducibility. Built-in 1800mA high
capacity rechargeable lithium battery, long standby, 2.0 inch
industrial grade high resolution color screen, perfect display of
various technical indicators and gas concentration values,
historical alarm data display on screen, data storage function
there is. The rubber casing is industrially non-slip design,
compact and easy to carry. Suitable for dry prevention, toxic gas
leakage and rescue, underground pipeline, mine, metallurgy, power
plant, chemical industry, tunnel, tunnel, etc. Effectively prevents
the occurrence of poisoning accidents, guarantees that workers'
safety is not violated and production facilities are not damaged.
