Hello Mr. Singhania ,

Good day , Just today I have received the Orders slotted weights and hangers .

I was not in a comfortable position till I open the packages, even with your confident communication due to my worst experience with other suppliers.

On opening the package I was extremely satisfied , as the packaging , the marking , painting finish and the quality was 100% beyond expectation .

Really appreciate the workmanship and you kept you word in maintaining Quality at its best .

Much impressed and looking forward for more business with you. I would love to recommend you to fellow industry people.

Regards / Mit freundlichen Grüßen

Dear Sir/Madam,

I am proud to be linked with you.


We, produce exclusively Cast Iron Weights since 1961. OIML appreciated our Weights in 1973. OIML recognized us as one of the supplier of Cast Iron Weights in their Guides (G 12 – Suppliers of verification equipment) published in Mars, 1987.


Manufacturing Cast Iron Weights as per OIML Recommendation is our specialty. We also manufacture as per design of buyer. Our range is 50g to 1000kg and 4-oz to 3000lb in all accuracy class.

We maintain quality of our products strictly as per International Standards with guaranteed accuracy. Our major production is being consumed by buyers from Germany, Canada, France, Australia, Netherlands, Belgium, U.K., Qatar, Dubai, South Africa, Ireland, Cyprus, Tanzania etc. etc.

Our Calibration Laboratory is accredited in accordance with ISO/IEC 17025:2017.

Calibrated Weights

Posted on

Calibrated Weights are used almost exclusively for adjusting and testing – (calibration of electronic balances). We therefore call them Test weights as this is their purpose of use. Adjusting a balance means that you are intervening in the weighing system, to make sure that the display is set to show the correct nominal value. And Calibration, on the other hand you are testing whether the display is correct and documenting any deviation. Regular servicing is essential for ensuring that a balance or a weighting device performs with specification. Thus adjusting and calibration both requires test weights, which are also used with weighing instruments of all classes. These test weights are also need to be protected and finely coated thus to properly adjust and calibrate our weighing machines, weighing instruments and other weighing systems.

The International valid OIML Directive R111-2004 classifies test weights hierarchically into accuracy classes with E1 is the most accurate and M3 is the least accurate weight class. As the appropriate test weight is only classified as checking equipment if it has relevant proof of accuracy. The whole test weight range in OIML accuracy classes are E1,E2,F1,F2,M1,M2,M3. With E1 being the most accurate and M3 being the least accurate one.

Cast Iron Slotted Calibration Weights & Hangers – M1 Accuracy

The  hanger weight is a weight in itself, that also has its weight Calibrated so that the hanger can be used as part of the overall weight under test,  and will hold a number of Cast Iron slotted weights depending on its usable shaft lengths. The slotted weights are discs with slots in them and are designed to sit on the hanger. Several Cast Iron Slotted Weights may be used together to build up from a minimum weight to a maximum test load.

These weights are used to test force gauges, crane scales or other suspended weighing scales. Cast Iron Slotted Weights are primarily used to calibrate large capacity scales.

Shanker Wire Cast Iron Slotted Weights are manufactured from a high quality iron. The surface are free of cracks, pits and sharp edges. All surfaces are smooth and free of scratches, dents and pores. Weights are protected by a durable coat of paint to protect the casting from rusting.

The M1 Cast Iron slotted hanger weights (Newton Cast Iron Slotted Weights, Kilogram Cast Iron Slotted Weights)  are the most common hanger weights we sell and are suitable for testing and calibration in the 5 N / 500 g up to 200 N / 20 kg.

Cast Iron Slotted Weight Hangers:

Cast Iron Slotted Weights are typically used with a hanger that also has its weight calibrated so the hanger can be used as part of the overall weight under test. Weight hangers are available in a variety of lengths and weight capacities. Hangers are calibrated to a mass value, and also have a capacity of how much weight can be loaded onto them.

Calibration Weight Certification:

You will normally need a calibration certificate to satisfy, if the tests that you do are on equipment that can effect the quality of your product and you are audited by an outside organization. Our Calibration Laboratory is NABL accredited in accordance with the standard ISO/IEC 17025 : 2017, So you can be satisfied with the quality and accuracy of the Cast Iron Newton Slotted Weights and Hangers.

Construction and General Shape:

Cast Iron Slotted Weights have adjusting cavities. Each weight has its nominal value cast into the topside of the weight. Weights are protected by a durable coat of paint to protect the casting from rusting.

Newton Weights

Posted on

A newton is defined as 1 kg⋅m/s2 (it is a derived unit which is defined in terms of the SI base units). One newton is therefore the force needed to accelerate one kilogram of mass at the rate of one metre per second squared in the direction of the applied force. The units “metre per second squared” can be understood as a change in velocity per time, i.e. an increase of velocity by 1 metre per second every second.

In 1946, Conférence Générale des Poids et Mesures (CGPM) Resolution 2 standardized the unit of force in the MKS system of units to be the amount needed to accelerate 1 kilogram of mass at the rate of 1 metre per second squared. In 1948, the 9th CGPM Resolution 7 adopted the name newton for this force. The MKS system then became the blueprint for today’s SI system of units. The newton thus became the standard unit of force in the International System of Units.

The newton is named after Isaac Newton. As with every SI unit named for a person, its symbol starts with an upper case letter (N), but when written in full it follows the rules for capitalisation of a common noun; i.e., “newton” becomes capitalised at the beginning of a sentence and in titles, but is otherwise in lower case.

In more formal terms, Newton’s second law of motion states that the force exerted on an object is directly proportional to the acceleration hence acquired by that object, namely: F = m a , {displaystyle F=ma,}

Where m represents mass of the object undergoing an acceleration a. As a result the Newton may defined in terms of kilograms as 1 N = 1 kg ⋅ m s 2

{displaystyle 1 {text{N}}=1 {frac {{text{kg}}cdot {text{m}}}{{text{s}}^{2}}}.}

Examples

At average gravity on Earth (conventionally, g = 9.80665 m/s2), a kilogram mass exerts a force of about 9.8 newtons. An average-sized apple exerts about one newton of force, which we measure as the apple’s weight. 1 N = 0.10197 kg × 9.80665 m/s2    (0.10197 kg = 101.97 g).

The weight of an average adult exerts a force of about 608 N. 608 N = 62 kg × 9.80665 m/s2 (where 62 kg is the world average adult mass).
