HOBO Bluetooth (BLE) Water Level Data Logger

Manufacturer: onset
Part Number: MX2001
Order / Quote

The HOBO® MX2001 is the industry’s first water level data logger designed for convenient wireless setup and download from mobile devices via Bluetooth Low Energy. The logger dramatically simplifies and lowers the cost of field data collection by providing wireless access to high-accuracy water level and temperature measurements right from a mobile phone or tablet. The MX2001 logger consists of a top-end unit and a water level sensor connected by a direct read cable. Cables can be ordered in lengths from 0.2 to 500m for deployment in a wide range of wells.

 

Pressure (Absolute) and Water Level Measurements MX2001-01-S and MX2001-01-Ti-S  -  9 Meter (30') range​
Operation Range 0 to 207 kPa (0 to 30 psia); approximately 0 to 9 m (0 to 30 ft) of water depth at sea level, or 0 to 12 m (0 to 40 ft) of water at 3,000 m (10,000 ft) of altitude
Factory Calibrated Range 69 to 207 kPa (10 to 30 psia), 0° to 40°C (32° to 104°F)
Burst Pressure 310 kPa (45 psia) or 18 m (60 ft) depth
Water Level Accuracy* Typical error: ±0.05% FS, 0.5 cm (0.015 ft) water Maximum error: ±0.1% FS, 1.0 cm (0.03 ft) water
Raw Pressure Accuracy** ±0.3% FS, 0.62 kPa (0.09 psi) maximum error
