Multi-gas monitor fumigates safely

OXON-BASED Crowcon now offers a multi-gas monitor designed to allow easier and safer fumigation of grain shed and silos.

The Custodian device has been developed to monitor levels of phosphine and oxygen, warning the user with audible and visual alarms if concentrations become unsafe.

Weighing 500g, the Custodian also monitors the "time weighted average exposure" to phosphine over 15 minute and eight-hour intervals, triggering the alarm if safe levels are exceeded.

The unit features an LCD display and a keypad which, according to Crowcon, enables quick and easy calibration.

Protected to IP66 safety standards, the Custodian costs £542 (01235-553057).
