  • Retrieve data in hard-to-reach locations
  • Visual alarms alert you to out-of-range conditions
  • Compact, weatherproof housing with built-in mounting
  • View current data in real time with Onset¢‚¬„¢s free HOBOmobile app
  • Share downloaded data easily from your mobile device
  • Accuracy: +/- 0.2C‚°

In what environment does this data logger operate?

This data logger operates in an outdoor environment.

What measurements does this data logger support?

The MX2303 data logger supports the following measurement: Temperature

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)
±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 (MX2301, MX2302 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: 0.05%
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
MX2301 internal sensor 17 minutes in air moving 1 m/sec 24 minutes in air moving 1 m/sec N/A
MX2302 external sensor 2 minutes, 30 seconds in air moving 1 m/sec 6 minutes in air moving 1 m/sec 5 minutes in air moving 1 m/sec
MX2303/MX2304 external sensors 3 minutes in air moving 1 m/sec; 20 seconds in stirred water 7 minutes in air moving 1 m/sec 4 minutes in air moving 1 m/sec
MX2305 internal sensor 17 minutes in air moving 1 m/sec 24 minutes in air moving 1 m/sec N/A
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
MX2301 internal sensor 1 minute in air moving 1 m/sec 1 minute in air moving 1 m/sec N/A
MX2302 external sensor 4 minutes in air moving 1 m/sec 4 minutes in air moving 1 m/sec 4 minutes in air moving 1 m/sec
Logger
Radio Power: 1mW (0 dBm)
Transmission Range : Approximately 30.5 m (100 ft) line-of-sight
Wireless Data Standard: Bluetooth Smart (Bluetooth Low Energy, Bluetooth 4.0)
Logger Operating Range : 40° to 70°C (-40° to 158°F)
Logging Rate: 1 second to 18 hours
Logging Modes: Fixed interval (normal, statistics) or burst
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.
