Latest Updates

Two new CE-EMC certifications.
Issued 29 May 2026.

Our Pt100 wire-wound RTD series has been independently tested and verified for EMC compliance under EU Directive 2014/30/EU. Both documents — the Verification of Conformity and the supporting 45-page Test Report — are issued by Shenzhen HongBiao Certification & Testing Co., Ltd., a CNAS-accredited test house (CNAS L12076 · ILAC-MRA recognised). Models tested: PT100-500MM · WZP-3×20-3P500 · WZPM-6×18-M8×0.75-3P1500 · JLPT100-500MM.
