Why Measure Temperature and Light?
Temperature and light levels are crucial environmental monitoring parameters that govern the type, population, size and vigour of the aquatic life of waterways. For example, light levels and temperature can affect:
- the photosynthesis of plants - insufficient or excessive levels could be detrimental to an ecosystem
- the rate of various chemical and biological reactions
- levels of dissolved oxygen in the water
- the metabolic rates of aquatic organisms; and
- the sensitivity of these organisms to pollution and disease.
Hobo MX2202 - Key Features & Benefits
- Bluetooth - The Hobo MX2202 introduces the convenience of wireless technology to water temperature and light monitoring applications, which means there’s no need for a shuttle or cables for the setup or to download data to a free mobile application for viewing, sharing, analysis and storage.
-
Configurable via the HOBOconnect Application so you can:
- calculate statistics; and
- set up on-board alarms to trip at user-set thresholds to then activate LED warning lights or enable burst logging - i.e., data logging at faster intervals when sensor readings exceed certain limits.
-
Designed for field applications:
- The Hobo MX2202 weighs in at a small and highly mobile 12.8g
- Easy to replace, long-life battery
- On-board mounting tabs ensure quick and straightforward deployment; and
- The Hobo MX2202 is waterproof up to 30 metres
- Powerful - While small, this data logger is capable of highly accurate measurements over extended periods, and boasts an impressive internal memory capable of storing 98,000 measurements.
