Description
Global Water® Refrigerated Composite Water Sampler Model WS700R, CD0500Features:
- Refrigerated Single bottle system is ideal for wastewater, industrial and environmental sampling — easy and reliable sampling method
- State-of-the-art design gives full control over sampling — does composite or discrete sampling
- Refrigerated sampler requres two 120 V outlets to power the peristaltic pump and refrigerator
- Rechargeable battery powers the control panel
- Refrigerator does not have a compressor and is coolant free
- Pump and bottle is controlled to collect type, size, and timing of sample desired
- Simple to operate no programming required — great for field sampling
- Output provided for use with optional datalogger
- Lightweight and easy to carry — even with full bottle, can be suspended in manhole for storm or sewer water sampling
- Relatively small footprint is easy to hide or camouflage and can be chained and locked to prevent vandalism
- Rugged construction for harsh environments
- Meets federal, state and local wastewater regulations
- Timed and external event triggered flow proportional sampling
- Delay timer allows starting multiple samplers in the field at the same time or to delay drawing after a triggering event for a better representation
- Adjustable and repeatable sample volume
- Peristaltic pump prevents sample contamination — automatic 15-second backflush clears pickup strainer and hose and empties hose so next sample is not contaminated
- Float switche located in bottle protects unit against overflow by turning off perstaltic pump when bottle is full
- Adjustable peristaltic pump collects 1 to 15 composite sample sizes from 50 mL to 2 L plus full bottle discrete setting or to a single sample time interval from 5 min. to 12 hrs. plus and external trigger mode for flow proportional samples
- CE Certified
- Optional external pulse-type flow meter can control water sample interval for true flow proportional sampling — Global Water® Open Channel Flow Monitor can provide flow proportional output signal for triggering the WS700 samplers; check for other options for third party flow meter with 4-20 mA output
