Portable Samplers
- Hach - AS950
The AS950 Portable Sampler makes programming, data transfer and operation more intuitive and virtually error-free.
Sampling has never been this easy
The 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 color display allows intuitive programming to make these critical, remote sampling applications virtually error-free. 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.
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.
Easiest and Most Intuitive Operation
The large full color display and intuitive programming give you access to all your programmable criteria on a single screen - eliminating scrolling through menus and supporting error-free operation.
Most Convenient Data Transfer and Programming Available
The AS950 is the only sampler that utilizes a USB drive to upload and download data and copy programs from one sampler to another.
Confidence in Your Sampling Process
The program status screen instantly communicates alarms, missed samples and program progress for quick and easy troubleshooting.
Field Convertible for Compact or Discrete Sampling
Weighing only 28 pounds (12.7 kg),the AS950 Portable Sampler is designed for accuracy and convenience. Quickly switch between composite and discrete sampling in the field. Configurable for single- or multiple-bottle applications, it is specifically designed for use in 18-inch manholes.
Easy Maintenance at Low Cost
Spring-mounted rollers provide long tubing life keeping maintenance costs low. The desiccant and pump tubing can easily be accessed; the replacement is possible without any tools. The rugged see-through pump cover is made for a quick visual inspection.
