Aircraft and Truck scale calibration often requires special adapters to simulate a tire.   Scales come in a variety of sizes and have specific tolerances.   The problem is that not many calibration laboratories use the right adapters, or consider the impact of the uncertainty of the reference standard used for calibration.

If you need to certify something is within a  tolerance of 0.1 % of applied force, you cannot use a standard with a 0.1 % accuracy. Measurement uncertainty must be taken into account and the further away from a NMI (National Metrology Institute) the larger the uncertainty will become. If the Uncertainty of the measurement is not less than the tolerance required, there will be significant risk.  If you need to get the most accurate measurement out of your scale, and want to minimize this risk, the Morehouse 804000 press will meet your calibration needs.

Aircraft Scale Calibrator


Morehouse Aircraft Scale Calibrator was designed to accommodate the large size, high capacity scales which are utilized to weigh aircrafts and heavy weight vehicles. As it applies to any other calibration machine, Morehouse Aircraft Scale Calibrator is as accurate as the reference standard with which it is used; load cell or proving ring.


Morehouse Aircraft Scale Calibrators are designed to speed the calibration and certification of scales, yet maintain the high degree of accuracy required for proper certification. The calibrator can be used to calibrate all kinds of truck and aircraft scales. Some scales include:


·         Intercomp

·         Jackson Aircraft Weighing  (JAWS)

·         GEC

·         Haenni

·         Rice Lake

·         Ohaus

·         Proform

·         Brechnell

·         Tanner Racing

·         Taylor
