Relative Humidity:

Units of Measure: %
Specification Range: 5 to 95% 25°C non-condensing
Operational Range: 0 to 100% 
Resolution: 0.1 %RH
Accuracy (+/-): 3%RH
Notes: To achieve stated accuracy, unit must be permitted to equilibrate to external temperature when exposed to large, rapid temperature changes and be kept out of direct sunlight. Calibration drift is typically less than ±0.25% per year.

        I have to learn more on using this for a tool. I do think it will help on getting car to run in different weather settings. Probably should have paid extra for option letting me download and save info. Can it be added to my version?

        Hi, The standard (non-LiNk) models can download data to a PC or a Mac only with the Kestrel USB Data Transfer Cable which can be found in our Kestrel Accessories section. If you want the LiNK model, we can send you a pre-paid return label for the meter you have. You can purchase the LiNK version anytime. The LiNK model can transfer data via Bluetooth to a smartphone along with the Kestrel App. The LiNK model can use the Kestrel Data Transfer Cable as well. If you have any other questions please ask!
