Its small reel and narrow coaxial cable make it convenient to transport between locations where a shorter measuring length meets the project’s requirements.\u003c\/p\u003e\n\n\u003cp\u003eChoose an 80 ft imperial configuration or a 25 m metric configuration. Both options listed on this page include the 10 mm diameter P10 probe. The imperial and metric models are separate cable configurations, rather than a switchable measurement setting.\u003c\/p\u003e\n\n\u003ch2\u003eManual Depth-to-Water Measurements\u003c\/h2\u003e\n\n\u003cp\u003eThe light and buzzer activate when the probe’s detection point reaches conductive water. Read the graduated cable at your established reference point to determine depth to water, then record the measurement manually.\u003c\/p\u003e\n\n\u003cp\u003eThe reel includes an on\/off sensitivity control and a battery test button. Follow the operating instructions to check the equipment before use and adjust sensitivity when required by field conditions.\u003c\/p\u003e\n\n\u003cp\u003eThe 102M does not automatically log readings or provide a digital depth display. It does not measure temperature, numerical conductivity, or oil\/water interfaces.\u003c\/p\u003e\n\n\u003ch2\u003eLaser-Marked Coaxial Cable\u003c\/h2\u003e\n\n\u003cp\u003eThe flexible coaxial cable has a durable polyurethane jacket with permanent laser markings. The imperial N2 cable is marked every 1\/100 ft, while the metric N3 cable is marked every millimeter.\u003c\/p\u003e\n\n\u003cp\u003eA braided copper outer conductor provides flexibility, while a stranded stainless steel central conductor provides strength and limits stretch. The narrow cable can be useful where access is restricted by installed equipment, provided the probe and cable can pass freely along the entire measurement path.\u003c\/p\u003e\n\n\u003cp\u003eGraduation spacing describes the distance between markings. It is separate from overall measurement accuracy, which also depends on equipment condition, water-contact confirmation, reference-point consistency, and measurement technique.\u003c\/p\u003e\n\n\u003ch2\u003eP10 Probe with Segmented Weights\u003c\/h2\u003e\n\n\u003cp\u003eThe stainless steel P10 probe is 10 mm (approximately 3\/8 in) in diameter. Its segmented stainless steel weight assembly adds flexibility and helps the cable hang straight during measurements.\u003c\/p\u003e\n\n\u003cp\u003eSolinst lists the probe body as 70 mm long and the weight of the probe with its ten segmented weights as approximately 174 g. The 70 mm dimension describes the probe body, not the complete weighted assembly.\u003c\/p\u003e\n\n\u003cp\u003eCheck clearance around pumps, tubing, fittings, and other restrictions before deployment. Do not force the probe past an obstruction.\u003c\/p\u003e\n\n\u003ch2\u003eChoose 80 ft Imperial or 25 m Metric\u003c\/h2\u003e\n\n\u003cp\u003eThe 80 ft model is suitable when your procedure uses feet and the required measurement position falls within that cable length. The 25 m model is suitable when your procedure uses meters.\u003c\/p\u003e\n\n\u003cp\u003eThese lengths are not exact equivalents: 80 ft is approximately 24.38 m, while 25 m is approximately 82.02 ft. Select the actual cable length and units needed for your work.\u003c\/p\u003e\n\n\u003cp\u003eFor deeper measurements, consider a full-size Solinst 102 P10 Water Level Meter instead of assuming that a longer cable can be ordered for the mini configuration.\u003c\/p\u003e\n\n\u003ch2\u003eApplications\u003c\/h2\u003e\n\n\u003cul\u003e\n  \u003cli\u003eManual water level readings in shallow monitoring wells\u003c\/li\u003e\n  \u003cli\u003eMeasurements in accessible standpipes and boreholes\u003c\/li\u003e\n  \u003cli\u003eField programs where compact equipment is easier to transport\u003c\/li\u003e\n  \u003cli\u003eRepeat observations of changing groundwater levels\u003c\/li\u003e\n  \u003cli\u003eMeasurements alongside installed equipment where sufficient clearance exists\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eContact Activated Carbon Depot for help selecting the appropriate configuration or requesting pricing for multiple meters.\u003c\/p\u003e","brand":"Solinst","offers":[{"title":"P10 \/ N2 \/ 80ft - 114861","offer_id":44939019681981,"sku":"114861","price":408.0,"currency_code":"USD","in_stock":true},{"title":"P10 \/ N3 \/ 25m - 114864","offer_id":44939019714749,"sku":"114864","price":408.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0664\/1408\/4285\/files\/solinst-model-102m-mini-water-level-meter-80-feet-p10-or-p4-972329.jpg?v=1750714401","url":"https:\/\/activatedcarbondepot.com\/products\/solinst-model-102m-mini-water-level-meter","provider":"Activated Carbon Depot","version":"1.0","type":"link"}
