Applicable to various water quality sampling: such as stormwater, industrial discharge, water and wastewater treatment, wastewater collection system, process control, sewers and rivers, etc
Two sets of sampling pumps, each capable of independent control
Time weighted mixed sampling, discrete sampling, or both types of sampling can be performed simultaneously
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
Lightweight, easy to carry, sturdy structure suitable for harsh environments
Rechargeable battery or AC power supply
