for environmental analysisfor detectionfor industrial use

Product Overview
FumiSense Pro PH3-Hi is a handheld phosphine (PH3) gas monitor designed to verify fumigation concentrations inside stacks, silos and ships. It features an inbuilt air sampling pump capable of drawing a sample from up to 30 m and an electrochemical sensor measuring up to 2000 ppm (optionally 5000 ppm). The backlit 20×4 OLED display provides clear readings in low light. The device supports user-configurable datalogging with date, time, warehouse/silo location and USB data transfer via supplied GUI.
