A temperature measurement system for determining a performance of a smoke generating device includes a temperature measuring device. The temperature measuring device includes an elongated carrier and a number of thermal sensors disposed within the elongated carrier. The elongated carrier is configured to be inserted into an elongated chamber of the smoke generating device. Each of the thermal sensors includes a sensing end exposed on an outer surface of the elongated carrier. When the elongated carrier is inserted into the elongated chamber, the sensing ends respectively detect a temperature of a number of heating members of the smoke generating device.
