Specially Designed for the pumps to 12 V, the device allows to obtain a low-flow sampling up to 40 ml / min or up to 10 ml / min, according to the EPA guidelines on sampling in the field, with the use of the special valve. 

To operate, simply connect the controller to the car battery via alligator clips, taking care to observe the polarity and the voltage is set to the minimum, and connect the pump to the controller using the feedback cigarette lighter socket. The system, equipped with a meter cable for connection to the battery, it starts with the pawl "Flow Control", which also regulates the pumping speed.

The controller can not operate if the supply voltage is below 11 V, this threshold is reached, a safety circuit interrupt the operation. Please see the information sheet of the pumps for details on consumption. To prevent damage to the pump or the regulator itself, be sure to connect the pump to the regulator strictly off via the pawl "Flow Control". If the regulator were to be powered by a car battery, please note that due to the high performance, the pump has a high consumption and the car, even when on, you may not be able to keep the battery charged sufficiently for a long time.
