Equipment:
The HOBO Pendant Temperature Data Logger/ Doc # 9531-D, MAN-UA-001/ Onset Computer Corporation is a waterproof, one-channel logger with 10-bit resolution nd can record up to approximately 6,500 (8K model) or 52,000 (64K model) measurements or internal logger events. The logger uses a coupler and optical base station with USB interface for launching and data readout by a computer.
Measurement range: -20°C to 70°C (-4° to 158°F)
Accuracy: +/- 0.47°C at 25°C (+/-0.85°F at 77°F)
Resolution: Temperature: 0.10°C at 25°C (0.18°F at 77°F)
