What is a PosiTector kit?
PosiTector Inspection Kits contain a PosiTector gage body (Standard or Advanced) with 1 or more probes and accessories in a convenient hard shell carrying case. Customize an Inspection Kit from a wide selection of gage bodies and probes.
What is a PosiTector 6000 used for?
The PosiTector 6000 FNDS probe measures the individual thicknesses of both the paint and the zinc layers in a duplex coating system with a single reading.
How do you zero a PosiTector 200?
Taking measurements with the PosiTector 200 is easy. First, it is recommended to zero the probe- simply clean the probe tip, hold it in the air, and select ‘Zero’ from the calibration menu.
How do you test for zinc coating?
There are two methods for measuring the zinc coating thickness of hot-dip galvanized steel; a magnetic thickness gauge and optical microscopy. The simplest and non-destructive way is to utilize a magnetic thickness gauge, as optical microscopy is a destructive test only used to resolve measurement disputes.
How is phosphate coating thickness measured?
X-ray fluorescence is a nondestructive and accurate technique for measuring the thickness of thin phosphate coatings. Scanning electron microscopy will be useful to determine grain size and uniformity of the coating, as reported by you.
What is TA on a PosiTector?
RH – Relative Humidity (measured) Ta – Air Temperature (measured) Ts – Surface Temperature (measured) Td – Dew Point (calculated) Ts-Td – Surface minus Dew Point.
How do you charge a PosiTector?
Battery Type Selects the type of batteries used in the PosiTector body from a choice of “Alkaline”, “Lithium” or “NiMH” (Nickel-metal hydride rechargeable). If NiMH is selected, the PosiTector will trickle charge the batteries while connected via USB to a PC or optional AC charger.
How do you measure thickness of coating?
Ultrasonic paint thickness gauges can measure the thickness of coatings on nonmetallic substrates. The probe of the paint meter contains an ultrasonic transducer that sends a pulse through the coating. The pulse reflects back from the substrate to the transducer and is converted into a high frequency electrical signal.
What does WFT mean in painting?
Wet film thickness, or WFT, is the measured thickness of any liquid applied coating while it is still wet. A wet film thickness gauge should be used by the applicator, as the coating is being applied, to ensure that the average applied thickness is representative of the tested wet film thickness required to meet Code.
What is DFT paint?
Dry film thickness (DFT) or coating thickness is arguably the single most important measurement made during the application and inspection of protective coatings. Coatings are designed to perform their intended function when applied within the DFT range as specified by the manufacturer.
What is the thickness of phosphate coating?
0002 and . 0006 inches and manganese phosphate coatings are typically between . 0002 and . 0004 inches thick.
How is phosphate coating applied?
Phosphate coatings are usually applied to carbon steel, low-alloy steel and cast iron. The coating is formed with a solution of iron, zinc or manganese phosphate salts in phosphoric acid, and is applied either by spraying the solution onto the substrate or by immersing the substrate into the solution.
What is TS TD?
Ts – Td – The surface minus dew point temperature is important. in judging the risk of condensation, or dew, forming on a surface.
How are environmental conditions measured?
Surface temperature. Relative humidity (RH) Dew point temperature. The difference between the surface and dew point temperatures.
How do you reset a PosiTector?
For issues related to the PosiTector Advanced Gage Body:
- Perform a Hard Reset* as follows: A) Power down the Gage and wait 5 seconds. B) Simultaneously press and hold the (+) and center buttons until the Reset symbol appears.
- Update your PosiTector gage body and re-attempt measurements.
