This option is also used for the ventilation of the chamber. It is designed to be used where a it is important to minimize water consumption. Rather than flushing the exhaust fog and water down a drain continuously, this fog and water is washed into a holding tank and reused to wash down more fog. This option will conserve water and reduce operating costs. This option is commonly used in combination with a Wet Bottom Drain Assembly.

The Wet bottom drain provides an inverted trap for the cabinet to drain but not exhaust. The height of the inverted trap determines the amount of condensation that will build up on the chamber floor. This build up of condensation on the floor of the chamber will increase the relative humidity in the chamber during the test.

Includes special heaters, CPVC internal box, and insulated cabinet and cover. Allows for the chamber to run at temperatures up to about 140 ^oF (160 is also available).

1. Polypropylene cover (replaces the PVC cover)
2. Insulation panels
3. Rubber liner (replaces the PVC liner)
4. CPVC dispersion tower (replaces the PVC tower)

All of the components on the chamber that would not stand up to 65 ^oC temperatures are replaced. The chamber is insulated to assist the chamber heaters bring the chamber up to temperature. The insulation panels also keep the user from being burned at these elevated temperatures.

This option is helpful to those labs that require or desire increased test temperatures. The standard chamber can test in temperatures up to 50 ^oC however the longevity of the chamber will suffer. Any testing above 40 ^oC on a continual basis is a good reason to have this option. Tests such as ASTM B360 (CASS testing) is a great candidate for this option.

This option will move the dispersion tower from the center of the chamber to the back wall of the chamber. The fog is dispersed from a “T” shaped horizontal dispersion system from the back of the chamber towards the front of the chamber. This option opens up the center of the chamber to provide maximum space within the test chamber. The slotted openings in the horizontal tube have adjustable baffles to assure uniform fog dispersion control. This assembly replaces the vertical dispersion tower.

Made of fiber composite which is lightweight, corrosion-resistant, rustproof, non-conductive and non-magnetic. Installed on the support racks of the chamber, resting on rack rungs. Will support up to 165 lbs/75 kgs each.

This is a digital pH meter complete with pH probe unit, 4 oz. polyethylene bottles of 4 and 7 pH buffer solution adjusting screw driver and plastic carrying case. Used to check the mixed solution and collected condensate in the chamber.

1.00 – 2.00 range in 0.010 divisions. Length 330 mm (13″). This hydrometer is used to check the mixed solution as well as the collected condensate to make sure it is within specification. This meter will read the specific gravity.

0 – 26.4% range. Length 300 mm (12″). This hydrometer is used to check the mixed solution as well as the collected condensate to make sure it is within specification. This meter will read the percent of salinity of the solution.

Consists of three Filter cartridges and one bracket assembly. The bracket assembly is mounted by the customer in a convenient location to the cabinet. The purpose of these cartridges is to convert standard water from the tap into Deionized water suitable for use in salt fog testing and humidity testing. Note: Water quality may vary in the cartridge depending on the characteristics of the water being treated. Extra Cartridges available. Minimum order three cartridges.
