The MiniVol® TAS is a versatile and reliable sampling platform that is attractive to end-users worldwide. Although specifically designed for “saturation” sampling, the MiniVol® has been routinely used in a wide variety of applications including prescribed burns, fugitive dust studies, remote location sampling, indoor air studies, fence line monitoring and ambient air sampling at remediation sites.

Improving upon the best in portable air samplers, the TAS leads the way for the next generation of innovative air sampling equipment.

Implementing patented low flow technology, the TAS delivers precise and accurate results in a lightweight compact device

How it works

The MiniVol™ TAS is basically a pump controlled by a programmable timer which can be set to make up to six “runs” within 24 hours or throughout a week. 

When used outdoors it may be hung from a universal mounting bracket mounted on a variety of structures, utility poles, trees, fence posts or on the ground using a tripod. The sampler is equipped to operate from either AC or DC power sources. In the DC operational mode, the sampler operates from a battery pack, thus making the sampling site independent of line power. 

The MiniVol™ TAS comes with two battery packs to accomplish continuous field sampling. A charged battery pack is capable of operating the sampler for a minimum of 24 hours on a single charge. 

The sampler is equipped with two “fault circuits”:

• A low battery circuit automatically shuts the sampler down should the lithium-ion (Li-ion) battery fail to supply sufficient voltage (above 13.0 volts) to the pump. This feature helps protect the battery which could be damaged if used continuously at low voltage. A “low-battery” indicator light alerts the operator of this condition.
• A low flow circuit monitors the flow rate. 

Should excessive accumulation of particulate matter or some restriction in the tubing cause the air flow to fall below approximately 10% of the set flow rate, the sampler shuts down and a “low flow” indicator light alerts the operator. An Elapsed Time Totalizer linked in parallel with the pump records the total time in hours of pump operation.
