Coatings are designed to perform their intended function when applied within the DFT range as specified by the manufacturer.
What is DFT and WFT in painting?
Dry film thickness, or DFT is a measurement of the dry and cured material after all liquid has evaporated. DFT = WFT x % volume solids. For a 67% volume solids material with a WFT of 18 mils, DFT = 18 x 0.67 = 12 DFT. By simply reversing the equation DFT can also be measured to determine what the applied WFT was.

What is Kolbe electrometer?
When charged the vane is repelled by the plate and hangs at an angle. An electrometer is an electrical instrument for measuring electric charge or electrical potential difference.
How does an electrometer measure current?
They measure voltage by means of "voltage balancing", in which the input voltage is compared with an internal reference voltage source using an electronic circuit with a very high input impedance (of the order of 10 14 ohms). A similar circuit modified to act as a current-to-voltage converter enables the instrument to measure currents as small as a few femtoamperes. Combined with an internal voltage source, the current measuring mode can be adapted to measure very high resistances, of the order of 10 17 ohms. Finally, by calculation from the known capacitance of the electrometer's input terminal, the instrument can measure very small electric charges, down to a small fraction of a picocoulomb.
What is the input resistance of an electrometer?
A modern electrometer is a highly sensitive electronic voltmeter whose input impedance is so high that the current flowing into it can be considered, for most practical purposes, to be zero. The actual value of input resistance for modern electronic electrometers is around 10 14 Ω, compared to around 10 10 Ω for nanovoltmeters. Owing to the extremely high input impedance, special design considerations must be applied to avoid leakage current such as driven shields and special insulation materials.
How does a vibrating reed electrometer work?
Vibrating reed electrometers use a variable capacitor formed between a moving electrode (in the form of a vibrating reed) and a fixed input electrode. As the distance between the two electrodes varies, the capacitance also varies and electric charge is forced in and out of the capacitor. The alternating current signal produced by the flow of this charge is amplified and used as an analogue for the DC voltage applied to the capacitor. The DC input resistance of the electrometer is determined solely by the leakage resistance of the capacitor, and is typically extremely high, (although its AC input impedance is lower).
What is the name of the device that records electricity?
Electricity readings may be recorded continuously with a device known as an electrograph. Francis Ronalds created an early electrograph around 1814 in which the changing electricity made a pattern in a rotating resin -coated plate. It was employed at Kew Observatory and the Royal Observatory, Greenwich in the 1840s to create records of variations in atmospheric electricity. In 1845, Ronalds invented photographic means of registering the atmospheric electricity. The photosensitive surface was pulled slowly past of the aperture diaphragm of the camera box, which also housed an electrometer, and captured ongoing movements of the electrometer indices as a trace. Kelvin used similar photographic means for his quadrant electrometer (see above) in the 1860s.
What is an early quadrant electrometer?
While the term "quadrant electrometer" eventually referred to Kelvin's version, this term was first used to describe a simpler device. It consists of an upright stem of wood, to which is affixed to a semicircle of ivory.

What is calibration of coating gauge?
Calibration is the process whereby manufacturers of a coating thickness gauge sets-up, during manufacture, to ensure that the gauge meets the required accuracy specification. The procedure normally requires the coating thickness gauge to be set to known values of thickness and checked on intermediate thickness values. In modern electronic instruments the values at key points across the coating thickness range are stored as reference points in the memory of the gauge.
How to test the accuracy of a coating gauge?
With the gauge adjusted to zero on an uncoated smooth substrate and set to a known thickness standard at or near to the maximum thickness, intermediate thickness standards are measured and the readings compared to the actual thickness of the standard. The errors are the differences between the values of the reading and the value of the standard. These are most conveniently expressed as a percentage of the reading.
How does coating gauge affect linearity?
Calibration of coating thickness gauges will be affected by the type of material, the shape and the surface finish of the metal substrate to be tested. For example the magnetic properties of steel alloys vary and the conductivity of different aluminium alloys and different non-ferrous metals, copper, brass, stainless steel etc. also vary. These variations can affect the linearity of a coating thickness gauge. This means that a gauge set-up on mild steel for example will read a different value for the same thickness coating on high carbon steel. Similar linearity effects are seen on thin or curved substrates and particularly on profiled substrates such as blast cleaned steel used for structural steelworks.
How does a permanent magnet work?
A permanent magnet is mounted on a balanced arm and the force required to pull this magnet from the surface of the coating is a measure of the thickness of the coating . Force is applied through a helical spring attached to the balanced arm at one end and to a scale wheel at the other. As the scale wheel is turned the force is progressively increased until the magnet lifts from the surface. The scale is drawn in thickness units rather than force and the thickness of the coating can be read against a pointer on the case of the instrument.
