Solinst Model 103 [110577] Flat Tape Tag Line with 3/4" x 1 ft. (19 mm x 30 cm) Weight & Metric Increments, 150m. The Solinst Tag Line uses a weight attached to a laser-marked flat tape and is principally designed for use during the installation of monitoring wells. The Tag Line also provides a simple method to measure the depth to the bottom of a well. It is also ideal as a multipurpose marked support cable. The Model 103 Flat Tape Tag Line uses a 3/8" (10 mm) PVDF flat tape. The tape has a break strength of greater than 220 lbs (100 kg). It has a thick dog bone design that prevents adherence to wet surfaces and allows it to hang straight. The well tape comes with laser markings every 1/100 ft. or each millimeter. Lengths are 100 ft to 1000 ft. (30 m to 300 m). The standard stainless steel tag weight is 1.5 lbs (0.68 kg) and measures 3/4" x 1 ft. (19 mm x 30 cm). A narrow tag weight, 1/2" x 1 ft. (13 mm x 30 cm), weighing 0.65 lbs (0.30 kg), is also an option. Tag weights have tapered ends to minimize hang-ups during deployment and return to the surface and can be clipped on and off the tape. This allows the use of the reel-mounted marked well tape for other uses, such as bailer or pump, and packer deployment.
