Sampling Pump BiVOC2, 2 Channels
- ideally suitable for sampling of VOCs and aldehydes with just one pump!
- BiVOC2 - the 2-channel sampling pump for air sampling
- 2-channel sampling pump BiVOC2
- precise control unit for each channel
- each channel can be individually set up
- 10 editable preset programs
- US-standard, German-standard and volumetric litres
- Configurable interval mode (since version 2.1)
- more cost effective than 2 single pumps (with comparable technical specifications)
The compact 2-channel pump BiVOC2 allows you to perform simultaneous dual air-sampling in the range of low volume flow starting at 0.1 litres/min.
Perfect for air-sampling on TENAX sample-media with 0.1 SL/min volume flow.
Of course, other sample-media can be loaded as well - such as activated carbon tubes, DNPH cartridges and silica gel - with a volume flow of max. 1.9 litres/min*.
*The maximum achievable flow rate is determined by the differential pressure dependent on the sample-medium.
You can freely store up to 10 preset programs.
Start delay and interval mode can also be configured, naturally.
BiVOC2 supports the volume types standard litres, normal litres and volumetric litres (with optional climate sensor HC2-S).
The data of the last 64 samplings can be viewed on the display.
The high target volume range of up to 5000 litres allows to use the BiVOC2 to generate a precise exchange rate for air in test chambers - along with “automatic” documentation when data logging is enabled.
The power of the pump is automatically regulated according to the current requirements. That way, a battery runtime of up to 15 hours can be reached.
Sampling is getting more easy and relibale with BiVOC2:
- Connect sample medium
- Select preset program
- Press start
The rest is done by BiVOC2 - you can address yourself unstressed to other tasks.
Technical data:
Number of sampling channels: 2 individually controlled channels
Volume flow: 0.1 to 1.1 SL/min per channel, dependent on the necessary negative pressure pre-selectable up to 1.9 SL/min (e.g. channel 1 with 0.1 SL/min and channel 2 with 1.9 SL/min)
Sampling air volume: 0.5 to 5,000 SL (US-standard litres 0 °C / 1013 hPa), Ls (German-standard litres 20 °C / 1013 hPa) and L (litres cur. temperature and air pressure, with optional temperature sensor)

Start delay: selectable for each channel from 5 seconds up to 24 hours
Interval mode: configurable to extend the sampling duration for combined samplings with the same time window (to avoid possible overload, since firmware version 2.1)
