hi,
i have just calculate uncertainty for my humidity probes. the calculated uncertainty are all based on different temperature and %RH. the temp points is from 5°C to 70°C & 12% rh to 95%rh. i have 6 humidity probes and all these probe are used to calibrate humidity chamber.
The uncertainty are as follow
5°C , 12%rh - ± 3.3%
5°C , 35%rh - ±3.5%
5°C , 50%rh - ±3.8%
5°C , 80%rh - ±3.8%
5°C , 95%rh - ±3.1%
20°C , 12%rh - ±3.3%
20°C , 35%rh - ±3.5%
20°C , 50%rh - ±3.7%
20°C , 80%rh - ±4.5%
20°C , 95%rh - ±4.8%
30°C , 12%rh - ±2.5%
30°C , 35%rh - ±2.7%
30°C , 50%rh - ±3.0%
30°C , 80%rh - ±3.8%
30°C , 95%rh - ±4.1%
45°C , 12%rh - ±2.5%
45°C , 35%rh - ±2.7%
45°C , 50%rh - ±2.9%
45°C , 80%rh - ±3.6%
45°C , 95%rh - ±3.8%
65°C , 12%rh - ±2.8%
65°C , 35%rh - ±2.9%
65°C , 50%rh - ±3.0%
65°C , 80%rh - ±3.7%
65°C , 95%rh - ±3.8%
70°C , 12%rh - ±2.8%
70°C , 35%rh - ±2.9%
70°C , 50%rh - ±3.0%
70°C , 80%rh - ±3.6%
70°C , 95%rh - ±3.7%
how do i present all this uncertainty to my customer so that they are able to see it more easily. or how do i make used of all this data?
because at different %rh, the uncertainty are different. if i calibrate a chamber at 25°C , 55%rh, which uncertainty should i used?
please advice. thanks in advance.
