It’s a great little sampler!
The GLS Sampler is designed for general purpose or priority pollutant sampling in municipal and industrial applications where a full-size sampler is too large. It collects composite samples, based on time or flow intervals, in 1- or 2.5-gallon glass or polyethylene bottles, or in 2-gallon disposable ProPak bags.
With GLS’s simplified programming, setup takes less than a minute. In the field, the operator simply calls up the program with two keystrokes, presses the “go” button – and the sampling routine begins. You can also key in an alternate program in the field, without losing your stored program.
- 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.
