• Ranked #1 by University Field Course
Best for accuracy, ease of use and performance
• Unique Bridge Proof Probe
Testwell sets a new standard for probe performance during pump test and for well sounding
• Best Resolution & Accuracy
1/100 ft or 1mm & 5x more accurate than white tapes
• Choice of Probe Diameters
Standard 5/8, 7/16, 3/8 or 1/4 inch diameter stainless steel and Teflon probes
• Hook and Cable Protector
Protects tape from casing and lets unit hang from casing
• 5 Times more Accurate
Five times more accurate than white tapes with complete polyethylene jacket to protect 1/100 ft or 1mm graduations and stranded stainless steel conductors
• Standard Sensitivity Control
Prevents false readings in high conductivity water and ideal for pump and draw down test
• Field-Tested & Award-Winning
Ranked#1 for accuracy, durability and ease of use since 1995. Many of the features found on the original SST units are also found in the new units. This design has been tested extensively in the field for several years now and is a reliable performer. The tapes meet or exceed federal specification US GGT-T_106E (U.S.A.) or EEC Class II (Europe) for a guaranteed accuracy of .008%. A flat spring steel core ensures tapes hang perfectly straight in large and small diameter wells.
This provides unparalleled accuracy when compared to the flat white tapes, where kinks in the tape introduce slight errors, in addition to the displacement of water changing the static level.
The WLM Water Level Meter set new standards for reliability and accuracy. This unit has a 5/8 diameter stainless steel and Teflon probe. It uses a shrouded probe and unique probe design to prevent bridging.
Bridging is often encountered during pump test with other units. All units carry a sensitivity adjustment for different water qualities, with a choice of internal or external controls. The time proven Sonalert buzzer is also used on all units.
