Diver Instruments

Van Essen Diver Instrument Series

The Van Essen Diver series are submersible pressure transducers and data loggers designed for a variety of applications:

• Groundwater monitoring
• Surface water monitoring
• Aquifer characterization
• Remediation
• Mining

TD-Diver:

The TD-Diver is based on an ingenious and proven concept and is acknowledged as the most reliable instrument for the autonomous measuring and recording of groundwater level and temperature.

Available in: 10, 20, 50, and 100-meter pressure ranges

• Easy installation in almost every well
• Compact size: Ø 22 mm - length 110 mm
• Memory: 72,000 records of time stamp, pressure, and temperature with backup
• Continuous and fixed length memory

Micro-Diver

The Micro-Diver is the smallest Diver. The Micro-Diver is a submersible datalogger for long-term uninterrupted, real-time water level monitoring using a pressure sensor when submerged at a fixed level under the water surface.

Available in: 10, 20, 50, and 100-meter pressure ranges

• Compact size: Ø 18 mm - length 88 mm
• 48,000 records of time stamp, pressure, and temperature
• 30-Point Pressure Factory Calibration
• Pre-programmed and user-defined pumping tests

Cera-Diver

Monitoring groundwater under potentially corrosive conditions, such as brackish water and seawater, requires a robust and durable datalogger.

Available in: 10, 20, 50, and 100-meter pressure ranges.
