Query: Acu-rite not really accurate

This model appears to be the closest to the one I have, which also includes indoor/outdoor humidity readings.The thermometer, both indoor and outdoor, consistently reads at least one degree higher than my three other thermostats, which all agree with each other. Sometimes the Acu-rite is higher by three degrees. Customer service says it meets the "industrial standard" of plus/minus two degrees, and can not be calibrated.The humidity reading is about 30 percent off from local TV and weatherstation readings.On the plus side, it does have a longer distance range than the other wireless thermometer I have.
