Onset MX2302A HOBO温度/相对湿度数据记录器 (40~70°C, 0~100%, external sensor)

Operating Range: -40° to 70°C (-40° to 158°F) 

Wireless Data Standard: Bluetooth Low Energy (Bluetooth Smart)

Time Accuracy: ±1 minute per month 0° to 50°C (32° to 122°F) 

Battery Type: 2/3 AA 3.6 Volt lithium, user replaceable

Memory: 28 KB (63,488 measurements, maximum) 

Weight:

   Logger: 75.5 g (2.66 oz) 

   Solar radiation shield bracket: 20.4 g (0.72 oz) 

Temperature Sensor:  

  Range: 40 to 70°C (-40 to 158°F) 

  Resolution: 0.02°C (0.036°F)

  Response Time: 

     Without Solar Radiation Shield: 3 minutes, 45 seconds in air moving 1 m/sec

     With RS1/M-RSA Solar Radiation Shield: 7 minutes, 45 seconds in air moving 1 m/sec
