A simple to use, continuous humidity chamber to meet the test condition required by ISO 6270. The Elcometer 1200/4 is of welded polypropylene tank construction. The PVC cover has two sides, each at an angle of 15 degrees to the horizontal.

The Unit is switched on and water is fed in, through the inlet pipe, under pressure (1-5 bar). Once the water is at the required level, the unit begins to heat and maintain the water to the set temperature (40°C ± 2°C / 104ºF ± 4ºF, and not less than 35°C / 95ºF for ISO 6270).

Up to 20 test panels, 150 x 100 mm (5.9 x 3.9"), are then inserted into the spaces in the PVC cover.

Note: To meet the ISO 6270 Standard, all 20 must be filled.
