The Sweating Guarded Hotplate, often referred to as the "skin model", produces accurate, repeatable measurements of the thermal resistance and vapor permeability of textiles. Measurement Technology NW's SGHP hotplate system was designed in accordance with ISO 11092, ASTM F1868, and NFPA 1971 to measure both Rct (thermal) and Ret (vapor) characteristics. Sweating capability is achieved through a porous wicking assembly on the surface of the test plate and its outer guard ring. SGHP systems include hotplate with variable speed airflow hood, gravity-fed fluid supply system, PC computer, ThermDAC control software, plus ambient temperature and humidity probes. The SGHP system is available in two sizes. More on the Sweating Hotplate

The Dry Guarded Hotplate system is a cost effective instrument designed to measure the thermal resistance (R-value) of fabrics in accordance with ASTM D1518 and other test standards in use worldwide. Accurate measurements of temperature and plate heat flux are used to calculate steady state thermal resistance for textile samples or insulation batting. The GHP system includes hotplate with lateral and lower thermal guards, a fabric hood for uniform ambient conditions without the need for an environmental chamber, plus MTNW's ThermDAC control and data logging system - which makes testing as simple as clicking the mouse and walking away. Two hotplate sizes are available. More on the Dry Guarded Hotplate

Our new Integrated Chamber features insulated stainless steel interiors and an ergonomic design that provides operators with a comfortable working height of approximately 42" (107cm) above the floor. These compact chambers are fully integrated to the SGHP-8.2 or SGHP-10.5 sweating guarded hotplates, and include a large insulated door with window, high intensity LED cabinet light, and a removable top shelf for preconditioning fabric samples. A uniform, recirculating airflow stream is achieved by means of a plenum located behind the workspace. Adjustable ports permit fine-tuning of the airflow stream. More on the Integrated Chamber
