Some of the products sold by Dawson China Co. , Ltd. are due for renewal or re-certification of explosion-proof certification, mainly involving natural gas flowmeters, explosion-proof tuning fork level meters, explosion-proof magnetostrictive level meters, explosion-proof flow switch through the PCEC explosion-proof certification, and update the certification.

PCEC is more than just a International Electrotechnical Commission, IECEX explosion-proof electrical testing lab. They are also accredited by CCS, the German Federal Institute for Physical Technology (PTB) , the French international inspection agency (BV-RCentraltLaboratorytoLCIELCIE) , RussiansCentrentre for the certification of explosion-proof and mining electrical equipmeCCVECCVE) and Chinahina Classification SociDet NorskerVeritasitDNV(DNV) . PCEC mainly includes explosion-proof inspection and certification of electrical/non-electrical products for explosive environment, Spot Check/Commission/arbitration inspection of explosion-proof equipment, atmospheric Environmental Test, environmental test for electrical and electronic products/type approval test of electrical equipment for ships and mobile platforms, motor inspection, international certification (IECEx, Atex, CU-TR, North n explosion protection certification, etc.) , in-use equipment testing, explosion-proof system testing and so on.
