Markes ACTI-VOC Low-Flow TD Sampling Pump
概要
- Robust, low-flow pump optimized for sampling volatile organic compounds (VOCs) onto thermal desorption (TD) sorbent tubes.
- Small, lightweight, easy to use, and intrinsically safe—ideal for personal monitoring and a wide range of other air and gas sampling applications.
- Compatible with any TD tube (up to a max flow of 350 mL/min); automatically compensates for different impedances, ensuring constant flow rates with any sorbent packing.
- Allows constant flow sampling from 20–200 mL/min and constant pressure sampling from 1–350 mL/min.
- Easy to calibrate via a simple screw-operated flow adjustment.
- Rechargeable NiMH battery ensures stable performance for over 8 hours.
- Supplied in a convenient carrying case with charger (110–230 V*) and accessories.
