The tiny TidbiT v2 Temp Logger has 12-bit resolution and a precision sensor for ±0.2°C accuracy over a wide temperature range. This new v2 version has more memory than the original StowAway TidbiT logger and communicates through a convenient Optic USB Base Station or HOBO Waterproof Shuttle. The rugged TidbiT v2 Temp Logger is waterproof to 300 m (1000 ft) and is equipped with an optic interface for data offload in the field, even when the logger is wet.

Features

• Accurate:
  
  • 2-bit resolution and precision sensor for ±0.2°accuracy over 0° to 50°C
  
  
• Real-time clock for better than ±1 minute per month time accuracy
  
• Easy to Use:
  
  • High-speed Optic USB interface offloads full logger in less than 30 seconds
    
  • Programmable start time/date
    
  • User-selectable sampling interval: 1 second to 18 hours
    
  • Uses popular HOBOware software for system launch and data retrieval
  
  
• Reliable:
  
  • Battery lasts 5 years (typical)
    
  • Battery level indication at launch
    
  • Offload data, check logger and battery status while logging using HOBOware software
    
  • Non-volatile EEPROM memory retains measurements even if battery fails
    
  • Blinking LED confirms operation
    
  • Optional protective boot for added protection

Specifications

• Measurement Range*: -20° to 30°C in water; -20° to 70°C in air

• NIST-traceable certification is available through Onset at additional cost.

Optic USB Base Station**

• Optic USB Base Station offloads full logger in less than 30 seconds
  
• Optical interface to logger eliminates unreliable connectors
  
• Easy USB connection to PC
  
• Operating Range: 0° to 50°C
  
• The Base Station is splash-proof (connection to computer is not)

NOTE: Using TidbiT v2 Temp loggers in wet environments (>90% RH) over 30°C for extended periods of more than 8 weeks cumulative may lead to premature failure. For applications over 30°C, use the HOBO Water Temp Pro v2 data logger. For Onset's lowest cost underwater temperature monitoring solutions, see the HOBO Pendant Temp data logger. For depths greater than 300 m see the HOBO Stainless Temp data logger.

Software Required

HOBOware software and an Optic USB Base Station with Coupler are required for operation of the TidbiT v2. The HOBO Waterproof Shuttle can also be used as a base station.

* Not for prolonged exposure to chlorinated water.
** The HOBO Waterproof Shuttle can also be used as a base station.
