Specifications

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 MX2301A and MX2302A: 0.02°C (0.036°F)
MX2303, MX2304, and MX2305: 0.04°C (0.072°F)
Drift <0.01°C (0.018°F) per year
Relative Humidity 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%
