Solinst 114625 3500 AquaVent 5 Water Level and Temperature Logger

Solinst, 114625, 3500 AquaVent 5 Water Level and Temperature Logger, 20m Range

Features:

• Gauged pressure sensor for highly-accurate water level measurements
• Maintenance-free integrated hydrophobic filters and desiccants - no need to replace
• Easy-to-access, user-replaceable batteries

It records accurate water level and temperature measurements in shallow groundwater and surface water applications. It combines pressure and temperature sensors, hydrophobic filters and datalogger within a 22mm x 173mm (7/8" x 6.8") stainless steel housing with corrosion-resistant coating. It uses a gauged pressure transducer; it is open to the atmosphere via a vented cable to surface. Atmospheric pressure is applied to the transducer diaphragm, providing a cancellation effect for barometric pressure. This results in actual water level recordings.

The vented cable and logger are protected from moisture by built-in desiccants and hydrophobic filters. The vented pressure transducer is made of Hastelloy, making it extremely durable and accurate in a wide range of temperature and monitoring conditions. The sensor provides an accuracy of 0.05% FS, and can withstand 2 times over-pressure without permanent damage. The robust memory can hold up to 150,000 data sets when programmed in Solinst Levelogger Software.
