i know how to calibrate oil/water temp and pressure sensors but how do i calibrate an air temp sensor. i have no way of creating a steady and adjustable adjustable air temp so can i use water? maybe place the sensor in a glove or something so it can be submerged without getting wet???
thanks, Dan

I would use an oven to heat the probe, and a fridge to cool it. I would wrap the sensor with a K-type thermocouple attached to a display, and when the temp stabilises at a value take a reading with the logger. 5 degrees, ambient (night and day can give a 20 degree spread), and 100 degrees should give enough values to calibrate a usable curve. I have an air temp sensor that I will use soon, and that was my plan.
