Water Temperature Data Loggers

Measuring water temperature has long been a hallmark of the Onset product line, and we are experts at providing accurate, low-cost data loggers that researchers can rely on.

Our suite of water temperature loggers includes four choices: the tiny TidbiT v2 for low-cost monitoring in tight spaces; the HOBO Water Temp Pro v2, featuring a durable streamlined case for extended deployment in fresh or salt water; and our affordably priced HOBO Pendant loggers for measuring both temperature and light intensity. We even offer temperature loggers rated for use at full ocean depth of 11,000m! Browse Water Temperature Data Loggers

Water Level Data Loggers

The HOBO U20 Water Level data loggers feature research-grade accuracy at a great price, and are extremely easy to use, with no cumbersome vent tubes or desiccants to maintain.

They are ideal for recording water levels and temperatures in wells, streams, lakes, and wetlands at depths up to 250 feet. A titanium model is available for salt water deployment in brackish wetlands and tidal areas. Browse Water Level Data Loggers

For real-time or remote water level monitoring see our U30 Remote Water Level Monitoring solution.

Water Quality Data Loggers

Onset Water Quality data loggers include the HOBO U26 Dissolved Oxygen logger for measuring concentrations of oxygen, and the HOBO U24 Conductivity logger for monitoring conductivity, and temperature in lakes, streams, rivers, estuaries, and coastal waters.

Both loggers feature unique sensor technologies developed for long-term deployments in water with minimal maintenance – all at a fraction of the cost of other water quality monitoring options. Browse Water Quality Data Loggers
