Overview

Standard Features

Overall diameter is only 16.5 inches (42 cm), so GLS fits easily into manholes as small as 18 inches (46 cm), and also easily drops into most offset manholes.
Dry weight is less than 25 lbs (12 kg), the lightest sampler in the ISCO line.
Hinged handle makes one-handed carrying a breeze.
The patented LD90 Liquid Presence Detector and ISCO pump revolution counting system deliver accurate, repeatable sample volumes time after time.

Applications

Wastewater effluent
Stormwater monitoring
CSO
Permit compliance
Pretreatment compliance

Options and Accessories

Composite Sampling bottle configurations (1-gallon or 2.5 gallon glass or plastic; 2 gallon ProPak disposable sampling system)
