We have WEEE, RoHS & REACH (Environment) and CE/RED (Radio) for the TRB141, but if GITEKI certification is compulsory then we only have the RUT240, RUT950, and RUT955. If the project requires additional certification like PSE, VCCI, MIC that too will have to be cross checked.
Please note that based on the size of the project if requested, Teltonika might extend the certification to TRB141 too (Please contact your area sales representative for more information regarding that)
