Hach AS950 Portable Compact 

AS950 Portable Compact Sampler Bundle, 115V, with 2.5 Gallon Bottle # ASP.CXXXC221XX  


  • Sampling has never been this easy:

The AS950 Portable Sampler simplifies sampling with a large, full-color display for intuitive, single-screen programming, USB upload and download capabilities and the ability to copy programs sampler to sampler to save time on tedious programing, and an error alert and status screen to eliminate uncertainty and simplify troubleshooting. Weighing only 28 pounds (12.7 kg), the AS950 Portable Sampler is designed for accuracy and convenience.

  • 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:

The rugged see-through pump cover is made for a quick visual inspection. Desiccant and pump tubing can easily be accessed; the replacement is possible without any tools. Together with the long pump tubing life, this keeps maintenance costs low. 


Alarm:  Configurable alarms that show on status screen and are recorded in diagnostics alarm logs. Alarms can be set for system diagnostics and logging such as program end, sample complete, missed samples and full bottle. Channel alarms are setpoint alarms for the recorded measurements (channels), such as pH, level and power supply voltage.

Certifications: CE, UL.
