Isco 1640 Liquid Level Actuator VOC Detectors (PIDs & FIDs) battery-operated meter that uses soundThe 1640 Liquid Level Actuator provides a simple, reliable way to trigger an Isco sampler to begin a sampling routine when the liquid level reaches a predetermined height. The 1640 comprises a conductivity probe that mounts above the stream, a control box that mounts on the sampler, and connecting cable. It can be used in conjunction with other devices such as a rain gauge or flow meter to trigger sampling on multiple conditions. With the control
