WATER SAMPLER Simplified water sampler features unique, easy-to-remove 2 oz./60 ml collecting bottle designed to work directly with the LaMotte Dissolved Oxygen Test Kit, eliminating sample transfer into a second collecting bottle. Samples overflow collecting bottle five times to ensure greater representation. Employing a calibrated line allows you to retrieve samples at controlled depths. For rapid descent and minimal drift in low currents, attach 2 lb. weight (included) to sampler. 6” Tall sampler contains 2-1/2” diameter cylinder with 3-3/8” x 3-3/8” square top and bottom
