Test And Validation

Meter testing facilities

The state of the art testing facilities allow meter validation to be performed to approval levels

The specialized 'In House' testing facilities allow TRINITY to perform almost all of the testing required to ensure that our products attain the requirements of approvals, which includes:

MTE PRS 400.3 & ZERA TPZ 308

These reference standards from Germany are used for calibration & testing of TRINITY Products.
