Description
Compare the Pumped Four-Gas Package
This four-gas listing combines internal pump sampling with a color LCD and the standard LEL, O2, CO and H2S channels. Compare it when the sample-drawing arrangement and pump-status display are part of the purchase decision. Other sensor combinations shown below require a separately confirmed configuration.
Listed Purchase Options
| Option | SKU |
|---|---|
| LEL + O2 + CO + H2S | GAS-R4K8-01 |
This online option is the listed LEL + O2 + CO + H2S combination. The additional sensor choices below are not extra channels included with this SKU.
Questions That Help You Choose
Is the standard gas combination suitable?
Start with the listed LEL + O2 + CO + H2S configuration. Do not treat every gas in the sensor-options table as an installed channel.
What distinguishes it from the diffusion model?
This listing includes an internal micro pump and displays pump status. Compare the diffusion model when an internal pump is not required by the plan.
What belongs in the package comparison?
Check the configured sensors, any required sampling accessories and the charging arrangement against the proposed package.
For the buying comparison, read portable multi-gas selection guide and pump vs. diffusion selection.
Compare four-gas diffusion option.
Compare a Model with Separate Pump Variants
The BH-4A product page offers standard and pump-assisted variants. This listing describes an internal micro pump and a color LCD. Compare the supplied pump arrangement, required channel combination and display information across the chosen variants instead of assuming the two packages have identical functions.
This portable pump 4 gas monitor draws air through a built-in micro sampling pump and simultaneously displays combustible gas (LEL), oxygen (O2), carbon monoxide (CO), and hydrogen sulfide (H2S) readings on one color LCD. It is suited to field and facility checks where active sampling is preferred over relying only on natural diffusion.
Four-Gas Pump Sampling
- Standard LEL + O2 + CO + H2S detection configuration
- Built-in micro sampling pump with 10 selectable suction levels
- Color LCD displays gas name, concentration, unit, time, alarm status, pump status, and battery level
- Chinese and English interface options
- Audible, visual, and vibration alarms with sound pressure above 90 dB
- Top flashlight, large back clip, and magnetic charging connection
Supported Sensor Options
The standard purchasable configuration combines LEL, O2, CO, and H2S sensors. Other four-sensor combinations can be customized from the supported options below; contact us to confirm the required gases and measuring ranges.
