Veidt Weighing is a Slot Hook Weight factory in china. Slot hook weight is a precision measuring tool specially designed for hanging weighing, mainly used in laboratories, industrial production and other occasions that require high-precision measurement. Unlike ordinary weights, the characteristic of slot hook weights is that they have a special groove or hook structure designed at the top, which is easy to hang on a balance or force measuring device for measurement.

These types of weights are usually made of stainless steel, brass, or special alloy materials, and their surfaces are finely treated to prevent oxidation and corrosion, ensuring that they can maintain accurate weight even after long-term use. The accuracy level of modern slot hook weights can reach F1 level or even higher, meeting various precision weighing needs.

Unique design features of slot hook weights

Groove/hook design: The most prominent feature of the groove hook weight is the hanging structure at the top. The groove design facilitates stable suspension, while the hook design is more suitable for quick loading and unloading. Some high-end models use rotatable hooks to achieve multi angle suspension.
Anti slip texture: The side of the weight is often designed with anti slip texture or grooves for easy access and placement, while avoiding accidental drops caused by hand slippage.
Magnetic isolation: Some professional grade slot hook weights have built-in magnetic isolation layers to prevent external magnetic fields from interfering with weighing results, making them particularly suitable for use in electronic balance environments.
Temperature compensation: High end models will consider the metal expansion coefficient at different temperatures to ensure weight stability in various environmental temperatures.

The main application areas of slot hook weights

Laboratory research: Used in physics and chemistry experiments to calibrate precision scales and measure parameters such as material density and buoyancy.
Industrial production: applied in fields such as automobile manufacturing and aerospace, testing material strength and component load-bearing capacity.
Quality inspection: As a standard weight, it is used by the quality inspection department for regular calibration of various weighing equipment.
Teaching demonstration: Visually demonstrate mechanical concepts such as force balance and lever principle in physics teaching.
Medical equipment: used for calibrating precision medical scales to ensure the accuracy of drug ratios.

Key points for the use and maintenance of slot hook weights

Correct usage method:
Use specialized tweezers or gloves for retrieval and placement, avoiding direct contact with hands
When hanging, ensure that the weight is vertical to avoid lateral forces affecting the measurement
Handle with care to prevent deformation due to impact
Weights of different precision levels cannot be mixed

Daily maintenance standards:
Regularly clean the surface using specialized cleaning agents and soft cloths
Store in a constant temperature and humidity environment
Avoid contact with corrosive substances
Regular inspection and calibration (recommended at least once a year)

Calibration cycle recommendation:
E1 level: 3 months
E2 level: 6 months
F1 level: 12 months
F2/M1 level: 24 months

Guide to purchasing slot hook weights

Determine the required parameters:
Required accuracy level
Usage frequency and environment
Weight range and combination requirements
Special functional requirements (such as anti magnetic, anti-corrosion, etc.)

Considerations for supporting equipment:
Match the load-bearing capacity and accuracy of the balance
Consider dedicated storage boxes and workbenches
Necessary auxiliary tools (tweezers, gloves, etc.)

As an important tool in the field of precision measurement, the design and technology of slot hook weights are still constantly developing. With the increasing precision requirements in manufacturing and advances in measurement technology, slot hook weights will continue to play an irreplaceable role in quality control, scientific research, and industrial production.
