Envco – Environmental Equipment

The full-featured 3700 Sampler collects sequential or composite samples based on time, flow rate, or storm conditions. 

·         Full-size performance and flexibility 

·         Accurate, repeatable, sample delivery 

·         Automatic compensation for changes in head heights

·         Automatic suction line rinsing to eliminate sample cross contamination.

·         User-friendly programming for all applications 

 
The exclusive LD90 Liquid Presence Detector and patented* pump revolution counting system deliver accurate, repeatable sample volumes time after time. This system gives you: 

The LD90’s non-contacting design is not affected by conductivity, viscosity, temperature, or liquid composition. There are no internal tubing connections, so cleaning and tubing replacement are fast and easy.

Basic and extended programming modes provide the versatility for practically any collection scheme: 

- Uniform time intervals

- Non-uniform time intervals

- Storm water runoff sampling

- Multiple bottle compositing

- Split sampling  


Superior sample preservation  

The ISCO 3700 automatic sampler has a thermal resistance of R-11 which allows maximum effectiveness for cooling samples. The base of the sampler is insulated by one inch thick foam, keeping the unit more rigid and less affected by ambient temperatures.

 The 3700 Sampler controller components are protected in a tough environmentally sealed enclosure. The enclosure meets NEMA 4X and 6 (IP67) requirements for submersible, watertight, dust-tight, and corrosion resistant operation. To give you added flexibility, the 3700 Series controllers are fully interchangeable for portable or refrigerated sampling.
