Envco – Environmental Equipment

Features:
• Research-grade measurements at an affordable price
• Waterproof to 120 meters (400 feet)
• Data readout in less than 30 seconds via fast Optic USB interface

The Water Temp Pro v2 Logger requires an infrared base station (number FS90706) or shuttle (number FS90707) and HOBOware software (each 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.
