TL;DR:<\/strong> Legal verification (ki\u1ec3m \u0111\u1ecbnh)<\/strong> confirms a measuring instrument meets statutory requirements \u2014 mandatory for Group-2 instruments and performed only by state-designated bodies in Vietnam. Calibration (hi\u1ec7u chu\u1ea9n)<\/strong> compares an instrument against a measurement standard to determine its error \u2014 voluntary, performed by ISO\/IEC 17025<\/strong> laboratories such as Techmaster Electronics JSC<\/strong> (accredited by ANAB, USA \u2014 certificate AC-1868).<\/p>\n

Where to get electronic equipment verified in Vietnam<\/h2>\n

For instruments subject to mandatory verification, go to state-designated bodies such as QUATEST 1\/2\/3<\/strong>, the Vietnam Metrology Institute (VMI)<\/strong> or provincial standards-metrology-quality centers.<\/p>\n

Scope note:<\/strong> Techmaster Electronics JSC<\/strong> provides ISO\/IEC 17025 accredited calibration<\/a> (ANAB, AC-1868) across 12 measurement fields \u2014 it is not a state verification body. For statutory verification needs, Techmaster advises customers free of charge and refers them to the appropriate designated body; for accuracy assurance of electronic instruments (oscilloscopes, spectrum analyzers, DMMs, power supplies\u2026), calibration at Techmaster is fast and internationally recognized through ILAC-MRA.<\/p>\n

FAQ<\/h2>\n

Can calibration replace legal verification?<\/h3>\n

No. Verification is a legal requirement for Group-2 instruments; calibration serves quality control. An instrument may need both depending on its use.<\/p>\n

Do factory electronic instruments require legal verification in Vietnam?<\/h3>\n

Most electronic instruments used in production (oscilloscopes, DMMs, spectrum analyzers\u2026) are not on the mandatory verification list \u2014 they only need periodic calibration under your quality system.<\/p>\n

Are Techmaster calibration certificates internationally recognized?<\/h3>\n

Yes. Techmaster\u2019s laboratory is ISO\/IEC 17025 accredited by ANAB (AC-1868); results are recognized globally through the ILAC-MRA arrangement.<\/p>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\n\t<\/div>\t\t<\/div>\n\n\t\t\n
