Description
Global Water® WS750 Automatic Wastewater or Stormwater Sampler, CT0000
Features:
- 2-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, discrete or both types of sampling
- Each pump and bottle is controlled independently to collect type, size, and timing of samples 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
- 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
- Rechargeable battery or AC powered — low power consumption; battery will power unit for several months on standby or up to 1/2 hr continuous sampling with both pumps running
- Float switches located in each bottle protects unit against overflow by turning off perstaltic pump when bottle is full
- Individually adjustable peristaltic pumps collect 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 WS750 samplers
