{"product_id":"in-situ-level-troll-400-data-logger","title":"In-Situ Level TROLL 400 Data Logger","description":"\u003cp\u003eUnless you need vented level data, the Level TROLL 400 is In-Situ's low-maintenance option: it measures and logs water level, water pressure, and temperature in non-vented (absolute) pressure ranges, with no desiccant required. That makes it ideal for long-term monitoring at flood-prone or high-humidity sites where a vented cable isn't practical.\u003c\/p\u003e\u003cp\u003e3D factory calibration and In-Situ's anti-drift system keep readings accurate, and durable titanium construction withstands harsh conditions in fresh or saltwater, groundwater or surface water. As part of In-Situ's shared ecosystem, it integrates easily with accessories, in-well telemetry, VuLink, and HydroVu Data Services, and Smart Addressing means you can swap in another In-Situ device without reprogramming.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e Twist-Lock Backshell\/Hanger sold separately.\u003c\/p\u003e","brand":"In-Situ","offers":[{"title":"Non-Vented, 30 PSIA (11m \/ 35 ft)","offer_id":48159363530942,"sku":"0099240","price":975.0,"currency_code":"USD","in_stock":true},{"title":"Non-Vented, 100 PSIA (60m \/ 197 ft)","offer_id":48159363563710,"sku":"0099250","price":975.0,"currency_code":"USD","in_stock":true},{"title":"Non-Vented, 300 PSIA (200m \/ 658 ft)","offer_id":48159363596478,"sku":"0099260","price":975.0,"currency_code":"USD","in_stock":true},{"title":"Non-Vented, 500 PSIA (341m \/ 1120 ft)","offer_id":48159363629246,"sku":"0099270","price":975.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0592\/9926\/6750\/files\/in-situ_level_troll_family.jpg?v=1726762871","url":"https:\/\/envirotechonline.com\/products\/in-situ-level-troll-400-data-logger","provider":"EnviroTech Services","version":"1.0","type":"link"}
