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.
The All-Weather Refrigerated (AWR) sampler base is designed to endure humid and highly corrosive environments, minimising damage caused by corrosive gases, rodents, and standing water to guarantee environmental integrity.
Accurate and consistent sample preservations
The custom-designed air-sensing thermostat controls temperature in accordance with USEPA and international guidelines, preserving samples regardless of outside temperatures and conditions.
