New Level TROLL 700H Meets the OSW Surface-Water Specification

Now you can 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.

Unsurpassed Accuracy

• Meet stringent USGS specifications—Level TROLL 700H is accurate to ±0.01 foot.
• Get superior accuracy under all operating conditions—The instrument is calibrated over the full pressure and temperature ranges.
• Collect accurate surface-water data with a gauged instrument—no barometric corrections are required.
• Receive a serialized, NIST^®-traceable calibration report with each instrument
  
  

Level TROLL 700H Ideally Suited to Surface-Water Applications

• Real-time measurement of hydrologic conditions, including peak streamflow and gage height
• Stream and river gaging
• Coastal deployments—tide/harbor levels, storm surge systems, and wetland research
• Stormwater management
