The Permeations measuring cell NW50 made out of glass, complete in support with three support feet and PTFE holder (for films < 0.2 mm) NW50 incl. silicone FEP-coated O-ring seals (2 × 56 mm + 1 × 62 mm)

• portable housing made of aluminium profiles and plexiglass
• ntegrated, ventilation-supported temperature controller to ensure that the required EN test temperature of 23 °C ±1 °C is maintained at normal ambient temperature using a heater (300 W) and a Peltier cooler (>100 W)
• integrated pump with a volumetric flow meter and controller for drawing in ambient air through a commercially-available combination filter (gas- and particulate filter)
• Permeation cell according to EN 16523-1 (replaces EN374-3)
• Compensation vessel for removing the tested air stream
• Technical specifications: 230 V, weight: approx.13 kg
• Dimensions: Height = 365 mm (460 mm with filter!), width = 450 mm, depth = 300 - 375 mm

• a PC-controlled multiposition valve for analysing six gas streams one after the other. In addition to the three glass permeation measurement cells (not in the scope of delivery!), the zero gas, a reference gas (such as isobutane/air) and a test gas at the test chemical breakthrough concentration can be measured with the test specimens
• a plexiglass housing with an exhaust gas nozzle for temperature control of the permeation cells, reference gas cell, test gas cell and the zero gas
• a temperature controller with a fan, a heater (300 W) and a Peltier cooler (>100 W) to pre-establish the temperatures of 23 °C ± 1 °C or 33 °C ± 1 °C
• a FID for the detection of hydrocarbon-containing test substances
• an evaluation program that generates Excel-compatible data (prerequisite: the PC must have a USB and Windows 7)
