Testing Released Water Vapor
Humiditest™ Complete System
-
The James Instruments Humitest System allows the concrete practitioner to monitor and ensure that a new structure is dry enough to proceed with the next phase of construction. This is especially critical for concrete structures requiring a coating, carpeting or similar floor or covering treatment. Installing such treatments before the concrete is sufficiently dry will typically cause expensive failures in the covering treatment. The only accurate way to ensure that the concrete is sufficiently dry enough to safely avoid expensive re-work is via a bore hole humidity test system, such as the Humitest System

Dual Vapor Gravimetric Sorption Analyzer
DVS Resolution
-
DVS Resolution’s key feature is the combined ability to precisely control and measure temperature and relative humidity while recording the highest resolution changes in mass. DVS Resolution uses a dry carrier gas typically nitrogen or compressed air for its operation. Digital mass flow controllers regulate flows of dry and saturated gases. Relative humidity is generated by precisely mixing dry and saturated gas flows in desired flow ratios which produce expected relative humidity. In a typical experiment a known concentration of water vapor is delivered over a sample placed inside the sample pan connected to the Surface Measurement Systems Ultrabalance™ measuring realtime mass changes caused by sorption or desorption of water molecules. Prior to sorption measurements, the sample can be in-situ preheated/dried at temperatures of up to 300oC.

Moisture Resistance/ Humidity Test
-
This test is performed for evaluating the resistance of component parts and constituent materials to the deteriorative effects of the high-humidity and heat conditions typical of tropical environments. Most tropical degradation results directly or indirectly from absorption of moisture vapor, and from surface wetting. These phenomena produce many types of deterioration, including corrosion of metals; physical distortion and decomposition of organic materials; leaching out of constituent components of materials, and detrimental changes in electrical properties.

Portable Sulphuric Acid Dewpoint Temperature Monitor
-
The fuels used in boilers, such as coal, heavy oil and natural gas, contains S. during the combustion process, S and O₂ form SO₂, and a small amount of SO₂ is converted into SO₃ under catalysis of Fe₂O₃, V₂O₅ and other catalysts. Under normal circumstances, the volume of SO₃ in the boiler flue gas is 1×10-6～50×10-6, and the water vapor is about 10%. When the temperature of the flue gas is below 200°C, SO₃ and the water vapor are completely combined into H₂SO₄ vapor. A small amount of H₂SO4 vapor will significantly increases the acid dew point. When the surface temperature of the boiler heat exchange equipment is lower than the flue gas acid dew point, the H₂SO₄ vapor will condense on the surface to become sulfuric acid solution with a concentration of about 80%, which will adhere to the surface of the heat exchanger and cause acid corrosion. Typical equipment that is prone to corrosion includes air preheaters, induced draft fans and flue walls.
