The Research Engineers precision clinometer has been specifically designed to accurately set the slope angle of PAPI system projectors. It has a precise longitudinal spirit level with a micrometer type screw adjustment calibrated in degrees and minutes. Instruments may also be fitted with an optional cross level. Needing no electrical supply, the clinometer is constructed in aluminium and stainless steel, and is supplied in a fitted protective case.
Overall accuracy of the Research Engineers PAPI clinometer is better than one minute of arc.
