Milwaukee-based GLI/Manning’s Model PSB is a completely self-contained sampler designed to help you meet your stormwater runoff monitoring requirements. It’s easily programmed for sampling based on a rainfall event and/or rise in storm drain water level. A tipping bucket rain gauge eliminates site visits after a rainfall and an RS-232 output enables convenient retrieval of the daily rainfall event log. The PSB is lightweight (18 lbs. with battery and empty bottle) and has a convenient carrying handle.
