Level meters
Durable and inexpensive, Solinst Model 102 Coaxial Cable Water Level Meters are designed to accurately measure water levels in narrow applications. They use a choice of two small diameter probe designs attached to coaxial cable. The heavier 3/8-inch-diameter P2 brass probe is ideal for deeper applications. The cable has accurate laser markings every 1/100 ft or mm, in lengths up to 1,000 ft (300 m).
