Holbach - Model BIVOC2V2 -2-Channel Sampling Pump

Perfectly suited for air-samplings on TENAX sample-media with 0.05 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. 2.0 l/min*.
*The maximum achievable flow rate is determined by the differential pressure dependent on the sample-medium.

The performance features of BiVOC2V2:

• 2 individually controlled channels
• 0.05 up to 2.0 l/min preselectable per channel. Sum of both channels max. 3.2 l/min
• Sampling volumes preselectable from 0.5 up to 5,000 liters
• Start delay from 1 second up to 24 hours
• Interval mode to extend the the sampling duration for combined samplings with the same time window
• Illuminated 4.3 inch color display with touch operation
• Connector for external temperature/humidity sensor HC2A-S
• Integrated barometric sensor
• Ring buffer for data of the recent 100 samplings including the sampling process data (logging)
• Integrated testing programs
• USB interface for PC connection
• USB interface for memory stick to export the sampling data
• Maintenance-free membrane pump with controlled brushless drive
• Lockable plug-in couplings with 3/16” hose nipples
• Robust anodized aluminum housing with two tripod sockets

The high target volume range of up to 5000 liters allows to use the BiVOC2V2 to generate a precise exchange rate for air in test chambers – along with “automatic” documentation when data logging is enabled.

Sampling is becoming even more easy and relibale with BiVOC2V2:

• Connect sample medium
• Select preset program
• Press start

The rest is done by BiVOC2V2 – you can address yourself unstressed to other tasks.

What is possible with BiVOC2:

This is a current application by Mr. Dr. Maraun, ARGUK-Umweltlabor GmbH, for sampling and identification of mercury in ambient air.

One channel with a pair of DOWEX activated carbon samplers and two activated carbon samplers on the other one. This allows to determine the total mercury as well as “ionic” mercury, especially “sublimate”.

Details can be found in the report of the study (in German).

The BiVOCControl software included in delivery can be used to:

• Easily set-up BiVOC2V2 (all settings can also be made directly at BiVOC2V2)
• Completely control BiVOC2V2 remotely
• Read, store and export the stored sampling data to EXCEL
• Update the firmware (BiVOC2V2 operating system)
• Change the adjustment data, e.g. during recalibration

The sampling data stored in BiVOC2V2 can be exported directly to a customer specific EXCEL template.

The sampling history can also be recorded in freely definable intervals and exported to an EXCEL spreadsheet. The EXCEL template can be adapted according to customer requirements.

The PC software BiVOCControl runs on the operating systems Microsoft Windows 7 and newer. Microsoft Windows and EXCEL are not included in the delivery of the PC software BiVOCControl.

BiVOCControl only supports BiVOC2V2.
