When you need to retrieve high-quality groundwater samples, low flow sampling systems provide an excellent way to retrieve accurate results. While the system is fairly new to the UK, it’s many advantages over more traditional sampling systems has seen its popularity in the industry grow rapidly.
Low flow sampling works by extracting the water at rates similar to ambient water flow, which in turn minimises the drawdown of the water level.
Water is typically extracted through the use of pumps, which also have the added benefit of helping to reduce the mixing of stagnant water with the water that needs to be tested. Here at Aquaread, we stock a variety of pumps to aid with your low flow sampling, including bladder, inertial and peristaltic.
During the testing, the system is able to detect parameters such as pH, EC and DO. Typically readings of these water quality parameters are read 3 times to ensure stability before sampling begins. As such, a successful low flow sampling should typically take you no more than half an hour.Read our complete guide to Low Flow Sampling
For regular low flow groundwater sampling work, the AP-2000 is the go-to choice. Not only can it measure pH, ORP, EC, DO and temperature, but you can add any of our ISE or optical sensors to better suit your project needs. Furthermore, they are suitable for both fresh and salt waters thanks to being constructed from rough marine grade aluminium.
We also offer flow cells that can be attached to the AP-2000 to ensure the equipment doesn’t need to be submerged in the water to get a reading. The cell can collect water from its base which then exits through an opening at the top. This helps ensure the water is evenly distributed over the sensor without needing to fully submerge it in the water itself.
