Measuring tools

Wiha measuring tools are precision measurement instruments including digital calipers like the digiMax 150mm model, dial calipers such as the dialMax ESD series, and folding rules up to 2 meters in length designed for professional industrial applications. These instruments serve mechanical engineering workshops, electrical installations, precision manufacturing facilities, and quality control departments where accurate dimensional measurement to 0.02mm resolution is critical. The product range includes both standard and ESD-safe variants for electronics manufacturing environments, with measuring capacities ranging from 150mm calipers to 5-meter tape measures for construction and assembly operations.

Key selection criteria for Wiha measuring tools include measurement range with the 150mm calipers offering 6-inch dual scaling, resolution specifications where digital models like the digiMax provide superior readability compared to dial variants, and construction materials affecting durability in industrial environments. The dialMax ESD calipers feature antistatic properties essential for electronics work, while the Longlife folding rules offer 2-meter capacity with metric graduations across 10 segments. Operating temperature range, measurement accuracy class, and housing protection determine suitability for specific workshop conditions, with stainless steel construction providing corrosion resistance in demanding applications.

Wiha measuring tools comply with DIN 862 standards for vernier calipers ensuring measurement accuracy within specified tolerance classes, while folding rules conform to accuracy class II requirements per DIN 6403. The ESD variants like the dialMax ESD model meet IEC 61340 electrostatic discharge protection standards with surface resistance values below 10^12 ohms, critical for electronics manufacturing environments. Digital calipers incorporate IP54 protection rating against dust and moisture ingress, and the stainless steel construction meets corrosion resistance requirements for industrial workshop environments where chemical exposure may occur during measurement operations.

The digiMax digital calipers feature LCD displays providing direct numerical readouts with 0.01mm resolution and automatic zero-setting capabilities, while dialMax dial calipers use analog displays with pointer mechanisms requiring visual interpolation between graduation marks. Digital models offer data output functionality for quality control documentation and faster reading in poor lighting conditions, whereas dial versions provide reliable operation without battery dependence and superior shock resistance in harsh workshop environments. The dialMax ESD variant incorporates additional antistatic properties with conductive coatings, making it specifically suitable for electronics assembly and repair work where electrostatic discharge protection is mandatory.

Wiha digital measuring tools like the digiMax calipers feature standard data output interfaces compatible with statistical process control systems and measurement data logging equipment commonly used in ISO 9001 quality management environments. The instruments require calibration against certified reference standards traceable to national metrology institutes, with calibration intervals typically set at 12 months for precision measurement applications. Workplace integration involves establishing measurement procedures per ISO 14253 guidelines, ensuring proper storage in temperature-controlled environments between 10-40°C, and training operators on correct measurement techniques to maintain the specified accuracy class throughout the instrument's service life.

Wiha measuring tools operate reliably within temperature ranges of 0-40°C with the digital models featuring IP54 ingress protection against dust particles and water splashes common in industrial workshop environments. The ESD-safe variants maintain surface resistance below 10^12 ohms per IEC 61340 standards, preventing electrostatic discharge damage to sensitive electronic components during measurement operations. Stainless steel construction provides corrosion resistance against cutting fluids and cleaning solvents, while the robust mechanical design withstands typical workshop handling forces without affecting measurement accuracy, ensuring long-term reliability in demanding manufacturing and maintenance applications.

Wiha measuring instruments require annual calibration verification against certified reference standards traceable to national metrology institutes, with more frequent checks at 6-month intervals in high-volume production environments where measurement accuracy directly affects product quality. Daily maintenance involves cleaning measurement surfaces with lint-free cloths and appropriate solvents, checking for mechanical damage or wear on sliding surfaces, and verifying zero-point accuracy before first use. Digital calipers need battery replacement typically every 12-18 months depending on usage frequency, while proper storage in protective cases maintains accuracy over the typical 10-year service life when handled according to manufacturer specifications and calibration schedules.
