The Solinst Model 101 Power Winder is lightweight, easy to attach to the frame of any size Solinst reel-mounted device, and designed to allow ease of use when deploying longer lengths of tape. The convenient Power Winder features adjustable arms and rollers to suit different size reels, as well as other types of Water Level Meters in the market. A standard drill or driver is used to provide power to the Power Winder, which turns the rollers that are in contact with the reel. The drill can be operated at various speeds, in forward and reverse, to turn the reel and unwind and rewind the tape.The Power Winder is ideal for use with Solinst Water Level Measurement Devices, but can also be used with Solinst Tag Lines or pump tubing reels, such as the Model 425 Discrete Interval Samplers. Reels using the Power Winder can be placed on the ground, on a Solinst Field Table, or other flat surface. Small reels can also be secured to a well casing using a tape guide or the optional cinch straps.
