Water Quality Monitoring
Human actions related to growth, urbanization, and industrialization are placing tremendous stress on water resources. Compounding this stress are risks related to climate change and global water scarcity, which further threaten the long-term stability of water supplies.
As an important measure to help protect waterways and aquatic ecosystems, water quality and water level monitoring can provide data and valuable insights that help scientists and water managers better understand the conditions of water resources and how those conditions change and are affected by development, agriculture, and other activities. Information such as water temperature, water level, dissolved oxygen, conductivity, salinity, pH, and turbidity can be invaluable in helping governments and municipalities control water pollution and make more informed water management and conservation decisions.
Onset provides research-grade data loggers for capturing accurate water quality and water level data. Simple to use, reliable, and easy to deploy, Onset’s data loggers are capable of operating in harsh conditions and a wide range of temperature extremes.

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 which are sold as a set, plus a direct read cable to connect them. Cables can be ordered in lengths from 0.2 to 500m for deployment in a wide range of wells.

The HOBO Water Temp Pro v2 is durable with 12-bit resolution. Complete with a precision sensor for ±0.2°C accuracy, this logger measures temperatures between -40°C and 70°C (-40°F to 158°F) in air and up to 50°C (122°F) in water. Its waterproof, streamlined case allows for extended deployment in fresh or salt water. Moreover, the Water Temp Pro v2’s optical USB interface makes it possible to offload data even while the logger is wet or underwater. A solar radiation shield is required to obtain accurate air temperature measurements in sunlight (RS1 Solar Radiation Shield, assembly required; or M-RSA pre-assembled Solar Radiation Shield).$129 -

This high-accuracy conductivity data logger is a cost-effective way to collect water quality data. The HOBO U24 measures and records both conductivity and temperatures in streams, lakes, and other freshwater sources. This logger is recommended for monitoring aquifers for saltwater intrusion and road and agricultural runoff. This product’s open access to its sensor simplifies cleaning and maintenance. The HOBO U24’s non-contact sensor minimizes measurement errors related to drift. In addition, the logger features software-based drift compensation.
The HOBO U24 Conductivity data logger features a non-contact sensor with a Titanium Pentoxide coating. This coating prevents the sensor from coming in contact with the water, which in turn prevents tarnishing or corrosion associated with traditional electrode sensors. This sensor coating is also inert, enabling fouling to be easily wiped off the sensor.$750
