AS950 Portable Standard Sampler Bundle

Sampling has never been this easy.

The AS950 Portable Sampler simplifies sampling with a large, full-colour 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 12.7 kg, the AS950 Portable Sampler is designed for accuracy and convenience.

Easiest and most intuitive operation

The large full colour 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 utilises 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 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.

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.
Automatic Shutdown Multiple Bottle Mode: After complete revolution of distributor arm (unless Continuous Mode is selected)
