Nutech 2703 Automatic Air Sampling Device – For VOC Sampling
The Nutech 2703 automatic sampling device is an ideal product for automated air sampling. It is useful for standard environmental testing, scientific research, and 3rd party monitoring. Features include: an integrated timer, flow control, pressure reading, leak checking, auto QA/QC, a smartphone app with access to full system control.
Compared with its predecessor 2701, the updated 2703 integrates the current limiter, timer and vacuum pressure gauge in one controller which makes it the most advanced air/gas sampler on the market.
The 2703 controller combines the function of : Flow Control + Timing + Pressure Reading
Standard Operating Procedure for the Collection of Volatile Organic Compounds for the EPA School Air Toxics Program listed Nutech 2701 as the designated air sampler.

2. Great Battery Performance
The 2703 features a high-capacity (8700mAH) Li-Ion rechargeable battery and has low power requirements, allowing it to last up to 7 days without recharging.
3. Strong Adaptability
- The 2703 has a durable plastic protective cover, and is both water proof and dust proof. It has the option of being upgraded to a stainless steel cover. It is also equipped with a filter kit, allowing for operations in all but extreme weather conditions.
- The unit’s modular design allows it to be combined with various sampling media, including cartridges, Summa canisters, and Tedlar® bags.
4. High Precision & Minimal Limitations
- The 2703’s precise flow control uses built-in high precision pressure and flow sensors. The unit avoids the blockage problems and limitations associated with other air samplers.
- Silanized paths minimize the carryover and contamination.
5. Quality Control
With automatic leak detection, the 2703 possesses real-time recording and a visual display of the sampling pressure and flow data. The real-time data and historical data can be queried.

Customer Testimonial
We have done some testing with the unit and found it to work well for some of our applications. We tested sampled concentration levels of about 50 VOCs that we commonly analyze and found no evidence of sample contamination – a challenge we have had in the past with another system. We also found the system to work reliably collecting a series of short samples.
