Legal Metrology Inspectorate (LMI) Verification Activities
The Legal Metrology Inspectorate (LMI) of the Trinidad and Tobago Bureau of Standards (TTBS) verifies measuring devices used for trade in the Republic of Trinidad and Tobago in accordance with the Metrology Act No. 18 of 2004. Verification determines the accuracy of the measuring device to ensure that consumers get their monies worth. Verification exercises are carried out on prescribed measuring devices, such as scales or fuel dispensers, to ensure that it is measuring accurately and reliably.
Devices that pass the verification exercise are affixed with a “yellow” verification pass sticker. This is a tamper proof LMI sticker that carries an expiry date, a unique device ID and the assigned number of the inspector who carried out the verification exercise. When a device fails the verification test a “not for use in trade” sticker is affixed to the device.
