Hobo Mx2304 External Temperature Sensor Data Logger - China

Overview

The HOBO MX2304 is a weatherproof data logger with one external temperature sensor.

Leveraging Bluetooth Low Energy, the logger enables easy, fast set up and data download directly from your mobile device, and provides high-accuracy measurements in harsh outdoor environments

Temperature Sensor Range MX2301 and MX2305 internal sensors: -40 to 70°C (-40 to 158°F)

MX2302 external temperature sensor: -40 to 70°C (-40 to 158°F)

MX2303 and MX2304 external sensors: -40 to 100°C (-40 to 212°F), with tip and cable immersion in fresh water up to 50°C (122°F) for one year Accuracy ±0.25°C from -40 to 0°C (±0.45 from -40 to 32°F)
