1. Response Time (Typical)
A response time of less than 1s to achieve 95% of the final measurement value is one of the unique features
of the MS-56. The small thermopile detector having a low heat capacitance and high thermal conductivity
responds quickly to changes of the solar radiation. To keep the detector-output stable and in perfect thermal
balance during changing environmental and solar radiation conditions, the detector body is isolated from the
sensor housing. When using a data logger with a sampling frequency of 1second, because of the fast
responding detector the measurement data are stored without losses of the natural radiation changes.
