I. Overall Product Positioning
BW Ultra Portable Multi-Gas Detector (with Built-in Sampling Pump)
This is a high-end BW gas alarm instrument specifically designed for confined spaces, under the Honeywell brand. It can simultaneously detect 5 types of gases. It comes with an electric suction pump as standard, which can extract gas from pipelines, deep wells, and internal tanks for remote sampling. It is a mainstream equipment for safety detection in chemical, oil and gas, municipal sewers, and confined space operations.
Complete Model Segmentation Explanation: HU-X1W1H1M1Q1-Y-N
Segmented breakdown of the code meaning:
HU-X1: Product series = BW Ultra’s new-generation multi-gas detection instrument mainframe platform
W1: Equipped with an internal electric sampling pump (for remote gas sampling)
H1: Standard H₂S (sulfur dioxide) sensor
M1: Standard CO (carbon monoxide) sensor
Q1: Fifth gas: VOC (volatile organic compounds) (PID (photodetector) sensor)
Y: Body shell color: Yellow standard industrial model
N: Standard configuration, no additional customization options
✅ The entire machine can detect 5 types of gases:
O₂ (oxygen) + LEL (lower explosive limit) combustible gas + H₂S (sulfur dioxide) + CO (carbon monoxide) + VOC (volatile organic compounds)
Measurement Range and Resolution of Each Gas Table
