Designed to enhance accuracy and prevent errors, this device ensures reliable results every time, giving operators the confidence that their sampling is being handled precisely.
The AS950 removes the complexity of programming while delivering consistent, reliable data. By simplifying workflows with its user-friendly operation and advanced features like USB data transfer and program copying, it reduces repetitive tasks and enables operators to focus on more critical responsibilities with ease and confidence.
Its real-time error alerts and status updates mean you’re always in the loop, so you can address issues quickly and avoid disruptions. Lightweight and highly portable, the AS950 adapts to both field and lab environments, offering dependable support wherever it’s needed.
With the AS950, your sampling tasks are no longer a source of stress. Instead, you gain peace of mind, knowing that this equipment is designed to work accurately and efficiently, empowering you to achieve optimal results with ease.
| 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. |
