Gas detector tube LPG-1

Product overview
Uniphos dosimeter tube measures the concentration–time product (dose) of phosphine over the full fumigation period. The device is similar in principle to gas detector tubes but captures integrated exposure by natural diffusion into the tube. Available pre-calibrated and supplied with a safe tube holder for handling.

Application

• Assessment of fumigation efficacy
• Mapping phosphine distribution inside fumigated spaces (silos, storage, containers)
• Proof of fumigation for shipping containers and exported goods

Features

• Measurement principle: diffusion-based integrated sampling
• Available ranges: 1–200×10³ PPM·hr (LPG-1) and 1–200×10² PPM·hr (LPG-2)
• Pre-calibrated tubes for immediate use
• Maintenance-free handling; supplied with safe tube holder
• Simple, field-compatible procedure
