Hobo Temperature Rh Data Logger - China

The HOBO MX2301 is a weatherproof data logger with built-in temperature and relative humidity sensors.

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 MX2301A and MX2305 internal sensors: -40 to 70°C (-40 to 158°F)

MX2302A 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)

±0.2°C from 0 to 70°C (±0.36 from 32 to 158°F)

±0.25°C from 70 to 100°C (±0.45 from 158 to 212°F), MX2303 and MX2304 only

Resolution 0.04°C (0.072°F)

Drift <0.01°C (0.018°F) per year

RH Sensor (MX2301A, MX2302A only)

Range 0 to 100% RH, -40° to 70°C (-40° to 158°F); exposure to conditions below -20°C (-4°F) or above 95% RH may temporarily increase the maximum RH sensor error by an additional 1%

Accuracy ±2.5% from 10% to 90% (typical) to a maximum of ±3.5% including hysteresis at 25°C (77°F); below 10% RH and above 90% RH ±5% typical

Resolution 0.01%

Drift <1% per year typical Response Time: Temperature (typical, to 90% of change) Without Solar Radiation Shield With RS1/M-RSA Solar Radiation Shield With RS3-B Solar Radiation Shield

internal sensor 17 minutes in air moving 1 m/sec 24 minutes in air moving 1 m/sec N/A

Response Time: RH (typical, to 90% of change) Without Solar Radiation Shield With RS1/M-RSA Solar Radiation Shield With RS3-B Solar Radiation Shield

internal sensor 30 seconds in air moving 1 m/sec 40 seconds in air moving 1 m/sec N/A

Logger

Memory Modes Wrap when full or stop when full

Start Modes Immediate, push button, date & time, or next interval

Stop Modes When memory full, push button, date & time, or after a set logging period

Time Accuracy ±1 minute per month 0° to 50°C (32° to 122°F)

Battery Type 2/3 AA 3.6 Volt lithium, user replaceable

Battery Life 2 years, typical with logging interval of 1 minute and Power Saving Mode disabled; 5 years, typical with logging interval of 1 minute and Power Saving Mode enabled.

Faster logging intervals and statistics sampling intervals, burst logging, remaining connected with the app, excessive downloads, and paging may impact battery life.

Memory 128 KB (63, 488 measurements, maximum)

Full Memory Download Time Approximately 60 seconds; may take longer the further the device is from the logger
