The Model HSS-12 heated sample conditioning system is designed for use with the SIM-12H heated sensor for use in applications where the dew point to be measured is higher than the ambient temperature. The individual SIM modules control the temperature of the components so that they are above the dew point, thereby eliminating condensation. The SIM Modules are not available individually, but as a complete heated sampling system, Model HSS-12. Using the HSS-12, dew points up to 85º (185º) can be measured with the Models M2 and M3 (digital mode). Dew points up to 50º C (122º F) can be measured using the Models E4, M3 (analog mode) or M4.
