Van Essen Instruments Micro-Diver

Pressure transducer with integrated logger

Part # 51144-6

micro-diver

The Micro-Diver provides reliable automatic measurement and registration of groundwater level and temperature data. Measuring a slim 0.7 inches (18 mm) in diameter and 90 mm in length, the Micro-Diver is the smallest groundwater level sensor in its class, and a great choice for monitoring wells that are too small to accommodate larger sensors.

The Micro-Diver is available in four ranges for monitoring the following depths:

  • 0 - 33 ft (0 - 10 m)
  • 0 - 66 ft (0 - 20 m)
  • 0 - 164 ft (0 - 50 m)
  • 0 - 328 ft (0 - 100 m)

In addition to internal data storage, the Micro-Diver can be connected to an external data logger, such as the Stevens DataLogic 3000, or data telemetry systems with the Diver-SDI SDI-12 output adapter, allowing the Diver to be used for real-time data monitoring applications.

Manual data download in the field from a Diver's internal storage can be done by utilizing the optional USB Interface Cable and connecting the diver directly to a desktop or laptop PC.

What's the Easiest and Quickest Way to Start Collecting Data and Access it Anywhere?

The Answer's in the Cloud.

eTracker is a cellular modem and "virtual" cloud-based data logger in one (meaning you don't need to install a separate data logger). Simply connect your sensor and a power source to eTracker and you're done. Configure (or reconfigure) anytime from any Internet-connected device, and use Stevens-Connect to retrieve your data, or forward it to your favorite software system.
