HOBO Water Temp Pro v2 Logger

Built to withstand extended periods of immersion, the compact HOBO® Water Temp Pro v2 Logger provides reliable, accurate underwater temperature measurement. The precision sensors and electronics are sealed in a durable case which is waterproof to 100’ and has almost neutral buoyancy for stability in flowing rivers, streams, and tidal estuaries. The logger is less than 5” long, and the low-visibility case keeps the logger hidden from view. An optional high-impact protective rubber boot is ideal for use during times of high water flow or flooding when the logger may come in contact with moving debris.
The Water Temp Pro v2 Logger requires an infrared base station (90706) or shuttle (90707) and Hoboware, available as a free download, or Hoboware Pro software (sold separately) for system launch and data retrieval. The associated couplers are included with both the base station and shuttle. In addition, the shuttle can operate as a base station for added flexibility in the field. The high-speed infrared communications offloads data in less than 30 seconds (requires USB port), and the infrared communications port is located opposite the bail end for convenient access while tethered. You can offload data, as well as check the logger and battery status, even while logging. A blinking LED indicates that the logger is recording data. To reduce visibility in the field, this feature can be turned off. Non-volatile EEPROM memory retains measurements in the event of battery failure. NIST traceable certification.
