Level TROLL
For Groundwater and Surface Water Applications

The Level TROLL® contains everything needed for water level measurement and data logging--level and temperature sensors, a data logger, internal power in a 18.3mm (0.72 in) diameter housing with a lot of exciting new capabilities. Since it is built entirely from rugged titanium (Level TROLL® 500 & 700) or 316L stainless steel (Level TROLL® 300) that is welded to eliminate o-ring seals, you can have total confidence in all applications, even marine environments. The Level TROLL® is the easiest way to monitor level ever!

Features:

• Ultra-rugged, all-titanium design - Perfect for fresh and marine water monitoring. No more worries about corrosion. Excellent for marine, brackish and acidic sites.
• Super accurate sensors - record minute changes in water level and temperature.
• TIG-welded seals - Prevents flooding of instrument.
• Ultra-low power system guarantees 5 years or 2-million data points - Forget changing batteries or running out of power.
• Uses external battery or line power - no worries about running out of power.
• RS-485 MODBUS, SDI-12, and 4-20mA - provides for easy connections to existing and online systems
• Twist-Lock(TM) connectors that “lock” tight -100% reliability
