Handling / Maintenance / Storage of class E weights
Handling / Use : Zwiebel offers a complete series of accessories allowing you to use your weights in optimal conditions (tweezers, grip handles, gloves, etc.)
Maintenance : To ensure the reliability of your results, your weights must be regularly dusted. As the surface condition of the weights must not be modified in any way, we offer you accessories adapted to the maintenance of your weights such as brushes or cleaning kits.
Storage : It is recommended to store standard weights and masses in their original boxes. Standard weights and masses without a box should be stored in appropriate locations (laboratory conditions, under a bell jar, etc.).

METROLOGY MASSES
Industrial masses from 100kg to 2t – classes F and M
These weights comply with metrological criteria in terms of material (roughness, magnetization, etc.), shapes, markings and tolerances (Maximum Tolerated Errors: EMT) defined in international recommendation OIML R111. The
F1 and F2 classes masses are made of stainless steel, those of classes M are offered in painted cast iron, with or without feet depending on the nominal masses, stackable or not. Compact, practical and easy to handle, the heaviest masses can be handled by forklift or using slings.
AREAS OF USE OF INDUSTRIAL MASSES
Weighbridge (industry)
Above-ground weighbridge
Road-rail weighbridge
Axle weighing On-board

STORAGE
It is recommended to store industrial masses in appropriate locations (for example, do not expose the masses to dust and dirt, do not store them in a humid environment, etc.).
Suspended masses from 1g to 20kg – 1N to 200N – classes M
These weights comply with metrological criteria in terms of material (roughness, magnetization, etc.), shapes, markings and tolerances (Maximum Tolerated Errors: EMT) defined in international recommendation OIML R111
Two principles proposed by Zwiebel :
– Slotted masses with support :
The system is made up of a support with a hook (secure device) and different slotted masses which are positioned on the support in order to constitute an overall weight or a scale of value. The support is made of stainless steel, the slotted weights of brass. These masses can be adjusted in kilograms or Newtons.
Furthermore, the support can be adapted, in dimensions and nominal value, to your needs.
– Weights with 1 or 2 hooks:
The masses can be hung individually in order to carry out the tests (1 hook) – The masses can be hung together (rosary) in order to carry out the tests at different values. These masses are made of stainless steel. (2 hooks)
AREAS OF USE OF INDUSTRIAL MASSES
Scale – Hook weigher – Dynamometer
Force – load tests (pantograph calibration)
Resistance and traction tests
Pressure and torque measurement
STORAGE
It is recommended to store the masses to be suspended in appropriate locations (for example, do not expose the masses to dust and dirt, do not store them in a humid environment, etc.).
STANDARD BASKET
Zwiebel also offers you standard baskets. Made of stainless steel, they make it possible to obtain a strong mass by combining parallelepiped weights of 5, 10 or 20kg.
Manipulatable by pallet pullers or slings, they favor linear measurements. A tailor-made solution that adapts to all areas to be controlled: pallet weighers, floor scales, etc. Our baskets are adjusted and calibrated like any metrology mass.
We have 2 standard models of 40 and 50kg , classified M1 allowing to contain weights of 20kg for loads of 250 and 500kg in total.
We can also make any type of basket on request. We will need to define its weight and the desired total range (with rectangular masses of 5, 10 or 20kg in stainless steel or cast iron).
