Gas detector tube MBr

Overview
Colorimetric gas detector tubes are sealed glass tubes containing a specific reagent that changes color when exposed to target gases. Air is drawn through the tube with a compatible sampling pump; the length of the resulting stain is proportional to the gas concentration and is read against the tube scale. MBr (Methyl Bromide) detector tubes provide quick spot measurements for fumigation monitoring and leak detection. Tubes are available in Uniphos (thick/thin) and KwikDraw (thin) formats and cover low-level to high-level ranges from 0.2 ppm up to several thousand ppm depending on the tube model.

Applications

• Spot checks and leak detection in fumigated structures and storage areas to support worker safety and operational control.
• On-site verification during fumigation, remediation or compliance inspections.

Features

• Pre-calibrated, single-use colorimetric tubes
• Wide measurement range across tube variants
• No routine maintenance required (consumable product)
• Lightweight and portable for field use
• Uniphos tubes compatible with ASP-40 air sampling pump
• KwikDraw tubes compatible with KwikDraw Deluxe Pump
