98ft/30m Well Water Depth Gauge, Water Levels Meter with Stainless Steel Probe, Well Waters Level Indicator Waters Levels Measurement with Stainless Steel Probe

This Battery Powered Water Depth Gage has accurate measurements with a repeatability error of less than or equal to 2mm. Designed with sturdy Structure and Components for use in reservoirs. Easily assess water levels when the contacts leave the surfaces.Specifications:Product name: water depth gageRange: 30m (98ft) or 100m (328ft)Resolution: 1mm/0.03inRepeatability error: less than or equal to 2mm/0.07Applicable temperature of the instrument: -20?--+60?/-4°F -- +140°FRequired: 9V battery (not included)Material: PVC+stainless steel probe; Configuration: Probe holder; Total weight; 100m version: 9.3 kg / (20.50 lb); 30m version: 3.74 kg (8.24 lb)Packing List 1::1* Water Depth GaugeNotes:1. Due to different lighting and screen settings, the item color may be slightly different from the picture.2. Due to different manual measurements, please allow a 1-2cm difference in size.3. The on-off is divided into first and second gears, with no functional difference. Equally they are voltmeter on-off gears. When turned on, the voltmeter displays the maximum voltage at this time. When using the first gear, the voltmeter displays 0.4. Please handle the probe with care when using it, and avoid bending the wire rope, especially the part close to the probe, to ensure the accuracy of the measurement and the service life of the equipment.

• 【Operating Principles】The Water Level Meter uses a solid stainless steel probe, connected to tape measure. The water levels gauge is powered by a 9V battery, saves the trouble of connecting another power cord. When the probe enters water the electrical circuit is completed, sending a signal back to the reel where a light and clearly audible buzzer are activated. The water level is then determined by taking a reading directly from the tape at the top of the well casing or borehole
• 【Accurate Water Depth Measurement】the measurement unit is centimeters, the minimum reading can reach 1 mm, and the repeatability error is ≤ 2 mm,the Probe is depth up to 30m(98.4ft), and the applicable temperature of the instrument is -20℃--+60℃, ideal for measuring well levels. The sensor at the tip of the probe provides consistent measurements with almost zero displacements. The probe uses a larger 0.59-inch (15 mm) diameter probe for easy removal and cleaning
• 【Structure and Composition】Steel ruler water levels gauge is composed of probe, steel ruler cable, receiving system and winding reel. It features 304 stainless steel probe with built-in waterproof contacts to ensure durability and waterproof performancefor long-time use. When in use, please handle the probe with care. Avoid bending the steel cable, especially the section near the probe, to ensure measurement accuracy and extend the device's service life
• 【Ergonomic Design】Standard reels are ergonomically designed for good balance and ease of use, with a stand-alone design, convenient carrying handle and an excellent brake. They are robust and smooth running. The battery is housed in a convenient battery drawer and each reel has a probe holder and brake. The reels are equipped with an on/off sensitivity control, light, buzzer and a battery test button
• 【Versatile Applications】Steel Ruler Water Level Meter provides a most accurate way to measure water levels. The meter is commonly used to measure the water level in wells, boreholes, tanks and Water-Pipes, particularly ideal for the observation of groundwater level in hydro power projects and inspectors who inspect dam body infiltration line. Not only be used during construction but also as a long-term safety monitoring for a project
