Introduction to WS705 Improved Portable Water Quality Sampler
Applicable to various water quality sampling: such as stormwater, industrial discharge, water and wastewater treatment, wastewater collection system, process control, sewers and rivers, etc
Time weighted mixed sampling, full bottle discrete sampling, and flow ratio sampling can be performed
Easy to operate - no programming requirements, set directly through a rotary switch
Pulse output for data logger (optional)
Delay enabled timed sampling or external pulse controlled sampling
The sampling volume is adjustable and can be repeatedly set
Peristaltic pump prevents sample contamination, automatically backwashs sampling tube and filter
Quick detachable sampling tube placed inside the casing for easy transportation
Equipped with wheels and a telescopic handle, it is as convenient to carry as a suitcase
Sealed rechargeable batteries and smart chargers extend battery life
Optional AC power or solar panel charging
