In-Situ Level TROLL 500 [0089010] Water Level & Temperature Logger, 11 m (35 ft.) Range (15 PSIG)

The In-Situ Level TROLL 500 Water Level Logger contains everything needed for water level measurement and logging - level and temperature sensors, data logger, and internal power - all in a 18.3mm (0.72 in) diameter housing with a lot of exciting capabilities. The instrument is built entirely from rugged titanium with TIG-welded seals, eliminating the potential for flooding from faulty O-ring seals.

The In-Situ Level TROLL 500 Water Level Logger offers Twist-Lock connectors that provide a secure connection between the sensor and cable. The Twist-Lock connectors are also extendable, allowing the user to easily lengthen the cable without purchasing a complete replacement assembly. In-Situ's new ultra low-power system guarantees 5 years or 2 million readings. For added flexibility, the instrument can also be powered externally. System integration is easy with built-in RS-485 Modbus, SDI-12, and 4-20mA communication output capability.
