Paul N. Gardner USA is now offering a Direct Sampling Procedure (DSP) kit for high speed and accurate testing in the field. The DSP Bresle Chloride Test Kit from TQC includes all of the necessary equipment for assessing the level of soluble salts on blast-cleaned surfaces prior to coating.
Included in the kit is a conductivity gauge used for the assessment of soluble salt ions as chlorides, sulphates and nitrates. The Bresle Kit complies with ISO 8502-6 and ISO 8502-9 standards, describing the Bresle Method, to assess the level of soluble salts using a Bresle patch or Bresle sampler, distilled water and a conductivity gauge. The conductivity is directly proportional to the concentration of dissolved chloride ions in the solution.
This test kit is also suitable for determining the contamination of blast-media in use. The company advises to always clean the instrument after use and says that if it is used frequently a thin film could form on the probe, which can be easily removed with a clean cotton swab and cleansing solution.

Paul N. Gardner USA, global distributors, producers, and designers of quality physical and inspection instruments for the paint, coatings, and related industries, has introduced a new offering: The compact, portable Sling Psychrometer.
As an easy way to measure relative humidity levels quickly, this uniquely compact Bacharach Sling Psychrometer accurately determines per cent relative humidity without the necessity of consulting complex tables. There is no need to wet the wick each time a reading is taken, and it contains a slide rule calculator which correlates wet and dry bulb thermometer indications for direct reading of relative humidity. When not in use, the thermometer case telescopes into the handle for protection.
The Sling Psychrometer consists of two thermometers that are turned by vigorously swinging the handle and exposing the thermometers to rapid air movement. These two thermometers are called dry bulb and wet bulb. The bulb of one thermometer is placed in direct contact with the room air to measure dry-bulb air temperature. The bulb of the other thermometer is covered with a silk or muslin sleeve that is kept moist to record the wet bulb temperature. Evaporation cools the wet bulb more than the dry bulb, and the humidity is obtained as a function of change in temperature. The atmospheric humidity is determined by calculations, steam tables, or using a psychrometric chart. Gardco.com
