The model A901 and A902 Slimline Biaxial
Clinometers delivers the same performance as
our model 900, but in a slim, compact package.
Units are available in horizontal (A901) or
vertical (A902) mounting packages. Standard
output is +/-2.5V or 0-5V DC. Units ship with
18” hook-up pigtail. Use the model A901 and
A902 for industrial pitch and roll
measurements, platform position and control,
OEM assemblies, and specialized instrument
packages where space is limited.
