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)

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

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.

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
