The Level TROLL 500 is a breakthrough for water level and temperature monitoring. The Level TROLL is a new product from In-Situ Inc and contains everything which is needed for water level measurement and data logging --level and temperature sensors and data logger. It can be powered internally by a 3.6V Lithium battery or can be powered externally.
The product is built entirely from rugged titanium which means it is perfect for all types of applications, even in tough marine environments. The Level TROLL is the easiest way to monitor level ever. The Level TROLL features a super low power system, built in RS-485/232 Modbus, SDI-12 and 4-20mA communication capabilities make system integration easy.
