Calibration Services

The process of establishing and rectifying the accuracy of a measuring or testing equipment.

BOBS Calibration Services
Calibration is critical in ensuring that measurement and test results from these instruments/equipment are accurate, trustworthy and reliable and as such assuring quality of the products.

Accreditation of Calibration Services :

BOBS temperature, dimension calibration services are accredited to ISO/IEC 17025 Standard as a third-party assurance that calibration laboratories are competent to carry out these services. Other services stated below comply with SADC Accreditation Services (SADCAS) TR09 requirements which entails measurement traceability compliance requirements. BOBS shall continue to accredit more services, keep on checking the website for the update….

Measurement Traceability and Internationally Recognised Measurements :

BOBS Standards used for calibration are all traceable to international systems of units (SI) therefore ensuring unbroken chain of comparison to SI. BOBS has its temperature measurements listed in the database of International Office of Weights and Measures (BIMP) confirming international recognition of temperature calibration measurements. Contact BOBS for more information…
