Level TROLL 700H Data Logger Meets the OSW Surface-Water Spec

Comply with the Office of Surface Water by using the industry's most accurate water level logger. The Level TROLL® 700H meets the surface-water specification of ±0.01 foot.

Use In-Situ Inc.'s high-performance Level TROLL 700H for surface-water monitoring applications. The gauged (vented) Level TROLL 700H can be used to:

  • Capture multiple peak flow events on one data log by using the Event logging mode.
  • Automate data collection at user-defined intervals—Uses standard Win-Situ® 5 and Win-Situ®Mobile Software
  • Log data by choosing one of six logging modes—Linear, Fast Linear, Linear Average, Event, Step Linear, and True Logarithmic.

Designed for Long-Term Deployments

  • Deploy the rugged titanium instrument in fresh water or saltwater and get reliable performance for years.
  • Access data when you need it by connecting to a TROLL® Link Telemetry System, MultiHop Data Radio, Con TROLL® PRO System, RuggedReader® Handheld PC, or a third-party data logger or sampler.
  • Get long-lasting batteries—Batteries typically last for a minimum of 10 years or 2 million readings. 8-36 VDC input is compatible with external batteries and solar panels.
