Kestrel 5000 Environmental Meter (without LINK)
As with all 5000 series Kestrel meters, they have both a white backlight, which is great for even daytime use, and a night-vision preserving backlight. The red night vision (NV) backlight incorporates optical filter to reduce overall brightness and minimize blue and green spectrum light to preserve night vision. (Note: This backlight appears soft greyish pink, not "red", and is still in the visible spectrum, so is not compatible with night-vision equipment.) Basically, with the red backlight, your eyes don't need to adjust when looking from your meter to the horizon in night time use.
The advantage the Kestrel 5000 provides to scientists, athletes, firefighters, automotive technicians, and agricultural specialists is immeasurable. With Kestrel 5000 technology, you will not only know the current weather conditions, but be able to track changes in the environment and therefore make predictions as to what may happen next.
With the new 5000 series (any) technology, the need to calibrate the RH is highly unlikely. Kestrel will stand by the RH for 5 years, and will adjust it within that 5 years if needed. Kestrel will repair, recalibrate or replace any defective product within the warranty period. Defective includes measurements outside of our accuracy spec plus stated drift.
