The HOBO Pendant Temperature Loggers are both miniature and waterproof, making it a sensible monitoring solution for specific temperature monitoring applications. The HOBO Pendant® Temperature/Alarm Data Logger has one-channel and is recommended for short-term shipping or long-term monitoring. This logger features a visible LED light indicator, which warns users when preset parameters have been exceeded. This model stores 6.5K of 10-bit temperature readings. Use a solar radiation shield for accurate temperature measurement in sunlight applications. See RS1 Solar Radiation Shield (assembly required) and M-RSA (pre-assembled) Solar Radiation Shield.
