Nutech 2703 Automatic Air Sampling Device

Nutech 2703 Automatic Air Sampling Device

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 2701 integrates the current limiter, timer and vacuum pressure gauge in one controller which makes it the most advanced air/gas sampler on the market.

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 current mechanical 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.

2701 Automatic Air Sampling Device (2703 Predecessor Model)

1. Adopting PLC control and automatically starting sampling program through time setting.

2. The 2701 has a stainless steel protective body, and is both water proof and dust proof. It is also equipped with a filter kit, allowing for operations in all but extreme weather conditions.

3. The unit’s modular design allows it to be combined with various sampling media, including cartridges, Summa canisters, and Tedlar bags.

4. Silanized paths minimize the carryover and contamination.

5. The 2701 uses capillary current limiter, which reduces the probability of blockage compared with orifice plate current limiter.
