Tel: 1-800-837-0864 ? 770-465-7557Applications:Measures the thickness of ?oating or sinking products in monitoring wells or storage tanks. Also detects the presence of water in storage tanks. This instrument has been ?eld proven for use in small (½ in I.D. wells) after several years of ?eld testing under actual ?eld conditions. Built into the reel is a hook allowing you to support the PWI on the well casing. This will protect the cable from sharp edges on the well casing.Bene?ts:? Raising the standard for performance and reliabil-ity. Designed to keep working despite normal wear and tear. The "smart" electronics will tolerate severe scratches and condensation which reduces the need to replace the prism or lens.? Available with 7/16 or 5/8 in Probe. Detects and mea-sures ?oating product in ½ in (12 mm) or larger wells.? Sensitivity Control. Get quick readings and prevent false positives of water or hydrocarbons. ? Superior resolution and accuracy. The tape is marked in 1/100 ft or 1 mm graduations.? Measure LNAPLs and DNAPLs with a pressure proof stainless steel probe.? Automatic Sleep function. Unit powers down after 10 minutes to protect battery life.? 10-year limited warranty on all components plus a lifetime warranty on the reel.? Proven and rugged optical sensor. Two separate sen-sitivity controls for the water sensing and ?uid sensing circuits allow the user complete control over the performance of the instrument.? Field tested. Based on our popular Rugged Reel and tape with accuracy, durability and ease of use. Tapes meet or ex-ceed federal speci?cation US GGG-T-106E (U.S.A.) or EEC CLASS II (Europe) for a guaranteed accuracy of .008%..PWI Product/Water Interface ProbeDetects and Measures LNAPL or DNAPL 7/16" or 5/8" ProbeSPECIFICATIONSOperating PrincipleWater Sensing ConductivityHydrocarbon Sensing Infra-red refractionPower 9 V batteryTape Lengths 50 - 2000 ft (15 - 600 m)Tape Jacket Material KynarProbe Diameter 7/16 in (12 mm)5/8 in ( 15 mm)Face Plates 9.25 in diameterOverall Height 14 inShipping Weight 8 lb (3.6 kg)ORDERING INFORMATIONTR-921 Product/Water Interface Probe, 5/8", 100 ft TR-922 Product/Water Interface Probe, 7/16", 100 ftTR-923 Product/Water Interface Probe, 5/8", 30 mTR-924 Product/Water Interface Probe, 7/16", 30 mAccessory:TR-925 Carrying Bag (all-weather canvass)Because viscous oils may adhere to the probe we suggest passing the probe through the product layer and record your readings while retrieving the probe.
