Onset^® HOBO® TidbiT MX2205 External Temperature Data Logger

Temperature Sensors. Range – Probe: -40°F to 212°F (-40°C to 100°C), with tip and cable immersion in fresh water up to 122°F (50°C) for one year. Logger: -4°F to 158°F (-20°C to 70°C) in air; -4° to 122°F (-20° to 50°C) in water, maximum sustained temperature in water 86°F (30°C). Accuracy – Probe: ±0.45°F from -40°F to 32°F (±0.25°C from -40°C to 0°C); ±0.36°F from 32°F to 158°F (±0.2°C from 0°C to 70°C); ±0.45°F from 158°F to 212°F (±0.25°C from 70 to 100°C). Logger: ±.45°F from -4°F to 32°F (±0.25°C from -20°C to 0°C); ±0.36°F from 32°F to 158°F (±0.2°C from 0°C to 70°C). Resolution: 0.018°F (0.01°C).
