HACH ASP.CXXXC121XX

The AS950 portable sampler is available in three base sizes to meet different requirements, available in 12V and 115V models with 2.5 gallon or 24 x 575mL bottles, are compact for smaller manhole applications, standard for a majority of applications and large to allow for large bottle composite sampling. For stormwater sampling, the AS950 portable sampler provides the ability to initiate up to two different programs based on user-defined conditions, such as rainfall or pH thresholds. The AS950 can be further programmed to collect varying sample sizes, collect samples at user-specified time intervals (i.e., time-weighted) or flow volume increments (i.e., flow-weighted), or collect samples over an entire run-off event as determined by a rain or flow sensor. For industrial pre-treatment monitoring, the AS950 portable sampler is available with a non-contact liquid detect to prevent cross contamination of samples, without cumbersome cleaning procedures. Ensuring a clean sample is quick with pump tubing replacement that requires no tools. A Hach Differential pH sensor can also be added to initiate a sampling program when thresholds are exceeded.

Typically used in pre-treatment water sampling or for compliance in wastewater, the AS950 Portable Compact is also capable of monitoring SARS-CoV-2 in sewage. Composite sampling serves as a comparison and may indicate an early warning of an outbreak. Once collected, sewage is ready to be further analyzed for viral loading and specific RNA sequences of COVID-19.
