Model PMH-2006精密温湿度仪

The Model PMH-2006 Precision Meteorological Hygrometer is a precision ambient dew/frost point measuring system with chilled mirror dew point sensor for outdoor or indoor test chamber applications. It provides the highest accuracy available on the market. Dew point temperatures above 0�C are determined to an accuracy of �0.2�C, while frost point temperatures down to -70�C have an accuracy of �0.5�C, using an intelligent, CPU-managed chilled mirror dew/frost point hygrometer sensor. Above 0�C, the hygrometer tracks the dew point temperature; below 0�C, it tracks the frost point temperature. Sensitivity �0.01oC. Slew rate typically 1.5oC/second. Zero hysteresis. CPU utilizing DSP technology performs continuous, automatic, and unattended ambient dew point measurements, and performs a daily heat cycle. 0-5Vdc analog and digital RS-232 interfaces. NIST traceable.
