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.

Temperature range is -4 to 158°F (-20 to 70°C) in air and -4 to 122°F (-20 to 50°C) in water. Accuracy is ±0.95°F from 32 to 122°F. Light intensity measurement up to 323,000 lumens/m² is also available. The logger is waterproof to 30m depth with sample rates from 1 second to 18 hours.
