Portable Samplers

The Hach AS950 Portable Sampler’s lightweight design, low power requirements, and easy mobility make it ideal for field applications, including stormwater, environmental, or industrial pre-treatment.

The AS950 controller is equipped with standard memory and USB connectivity allowing all data to be logged and transferred via USB drive, so a laptop is not needed in the field. Plus, the large, full colour display allows intuitive programming to make these critical, remote sampling applications virtually error-free.


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.

The AS950 portable sampler is available in three base sizes to meet different requirements; compact for smaller manhole applications, standard for a majority of applications and large to allow for large bottle composite sampling.
