MASTER applies stringent quality control at all stages of the sensor production. We carry out final tests using standard automated procedures. Sensor specifications are monitored under your application's operating conditions, as defined by your technical staff. MASTER utilizes a fully equipped laboratory where all tests, measurements and inspections are carried out in order to guarantee our customers the highest quality manufactured products.

The quality control inspection tests carried out by MASTER include the following:

• Ambient temperature insulation
• Hot insulation
• Electric strength test
• Resistance measurement and inspection in compliance with standards at different temperatures
• Thermal cycles
• Calibration
• Vibration test
• Dye checks
• Ultrasonic testing
• X-Ray
• Pressure test
• Surface roughness

The calibration/gauging of thermometers and thermo elements are executed in thermostat-regulated baths by comparison with apposite probes calibrated by a certified institute and comply with relevant international standards.

MASTER can provide regular certificates for the test/inspections mentioned upon Customer's request.

MASTER's products can easily comply with service requirement thanks to our own calibration Laboratories for thermocouples. This comes as the result of a collaborative development made with the Genoa University Engineering Department and which is now managed by WESTEAM.
