The secondary standards and/or systems cover the parameters temperature, pressure, humidity, and wind speed. The actual standard or transducer is integrated into a system which simulates an environmental parameter such as temperature. Most of these systems are interfaced to a PC which provides control of the system and data collection of the sensor(s) under test. This provides for a user friendly environment along with faster turn-around-times.
