Temperature and Humidity (TH) Measurements

NSCL maintains the reference measurement standards of temperature and humidity for Syria and for the dissemination of the related units of measurement. Temperature measurements are based on the International Temperature Scale (ITS-90).
The temperature standards are a Standard Platinum Resistance Thermometer (SPRT), and a Standard Thermocouple Type S (Platinum-Rhodium). The Temperature measurement services cover the full range of (- 50 to 1100) °C.
The humidity standard is a two pressure humidity generator and the range covered is (10 to 95) % RH.
