Description
Global Water® WL500-400 Water Level Sounder, 400 ft., AHG000
Additional sizes:
Features:
- Precision measurement, simplicity, and durability — meets or exceeds federal specification US GGG-T-106E (USA) or EEC CLASS II (Europe) for a guaranteed accuracy of 0.008%
- Detect water levels and well bottoms with high precision — unique design prevents bridging that is often encountered during pump tests with other water level sounders
- Trouble-free operation in wells with falling water and heavy oil slicks, even if well is not cased — two conductors make a separate ground connection unnecessary and allows instrument to function equally well in cased or uncased test holes or wells in rock
- Polycarbonate sturdy reel (light aluminum reels for units with over 400 ft. cable — improved durability, cranking and ergonomics)
- All load bearing components made of aluminum
- Durable polyester powder-coated steel frame
- Corrosion-resistant stainless steel fittings
- Large, ergonomic brake and soft grip vinyl winding handle
- Water and dust-proof encapsulated electronics — electronics can be removed to allow cleaning and decontamination of tape and reel
- Strong and accurate NTS certified tape with stainless conductors —reads accurately to 0.01 foot or 1 mm
- Full depth-rated stainless steel and Teflon probe
- Long lasting flexible link between the tape and probe
- Flat spring steel core ensures that sounder hangs perfectly straight in large or small diameter wells for accuracy of measurements — no kinking to introduce errors and displacement of water changing static level
- Sensitivity adjustment for different water qualities prevents errors due to very pure water or very conductive water — ideal for pump and draw down tests
- Tape marked in 1 foot and 0.01 foot intervals
- Audio alert beeper and LED indicate contact with the water — audio alarm will cease when the specially engineered tip detects the bottom of the well
- Battery operated — no danger of shock from outside power supply
