The GX-Force Sample Draw 4 Gas Monitor is a portable multi-gas monitor designed for personal monitoring, confined space entry, leak investigation, and field safety applications where remote sampling is needed before entering or working near a potentially hazardous area.
The unit monitors common confined space gases, including combustibles, oxygen, carbon monoxide, and hydrogen sulfide, and includes an internal sample pump for drawing air samples from a distance.

Its lightweight design, rechargeable battery, and field-replaceable sensors and filters make it a practical option for industrial teams that need portable gas detection with sample draw capability.
