±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


0.04°C (0.072°F)


<0.01°C (0.018°F) per year


Sensor Humedad Relativa (sólo MX2301 y MX2302)


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%


±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




<1% per year typical


Tiempo de Respuesta (typical, to 90% of change)


MX2301 and MX2305 internal sensors: 17 minutes in air moving 1 m/sec
MX2302 external sensor: 2 minutes, 30 seconds in air moving 1 m/sec
MX2303 and MX2304 external sensors: 3 minutes in air moving 1 m/sec; 20 seconds in stirred water
