Tester Calibration Services

In the Brinell hardness test, a hardened steel or carbide ball of known diameter is pressed into the surface of the material under a specified load. After removing the load, the diameter of the indentation left on the material is measured. This measurement is used to calculate the Brinell Hardness Number (BHN), which indicates the material’s resistance to deformation and overall hardness.

Insulation testers apply a high-voltage, low-current DC charge to measure resistance in wires, cables, and motor windings. This helps detect leakage current and identify damaged or degraded insulation that could lead to arc faults, circuit failures, electric shocks, or fire hazards. Insulation resistance testing is crucial for ensuring safety, preventing short circuits, and maintaining equipment reliability. It is widely used across various sectors, including industrial facilities, commercial buildings, and residential properties, to protect both personnel and electrical systems.

A leakage tester is used to detect and measure the escape of liquids, gases, or vacuum from sealed systems and components. It works by applying pressure to identify defects that may cause leaks. When leakage occurs, substances naturally flow from areas of higher pressure to lower pressure. In a basic leak decay test, pressure is applied to a specific volume, then isolated, and any pressure change is monitored over time. The collected data helps determine the leak rate. Additionally, using a 3/2 (three-way) and a 2/2 (two-way) valve in series enables effective isolation of pressure within the test volume for accurate results.

Torque testers are instruments used to measure opening and closing force, turning force, and sliding resistance, with readings displayed in units such as N·m, N·cm, kgf·m, kgf·cm, lbf·in, or ozf·in. They are commonly used to evaluate the safety, performance, and operability of components and finished products while ensuring compliance with industry standards. Calibration services for torque testers ensure accurate and reliable measurements by verifying the instrument against certified reference standards. Regular calibration improves precision, reduces measurement errors, and maintains consistency. It also ensures dependable performance in quality control, manufacturing, and testing applications across various industrial sectors.
