Accuracy ±0.05%FS, with KELLER test report ex works (standard)
Keller uses pressure sources to calibrate its products that are at least four times more accurate than the product to be tested. This enables us to produce products in our factory with an absolute accuracy of up to ±0,05%FS.
Higher Precision and Accuracy are available on request (0.025% and 0.01%). Please contact us for more details and pricing for any unlisted options.
