5” models are equipped with high strength composite plastic case.
10” models use cast aluminum enclosure.
Corrosion protection: Pressure bar protected with
durable powder coat paint. Shackles and pins are
electroless nickel plated. All integral machining and
fasteners are produced from noncorrosive materials or
have suitable plating.
Zero control: Zero up to 20% of capacity. Zeroed load
must be considered as part of ultimate load.
Calibration: Traceable to NIST.
Documentation: Includes User’s Guide and signed
