Pachet masurare, Ransburg 76652-03, verificat conductivitate suprafete, conductivitate vopsea

By measuring the surface resistance of materials normally considered to be electrically nonconductive and indicating the degree of sprayability on a standard scale, the Sprayability/Paint Test Meter can determine whether such materials can be electrostatically sprayed.

Designed to provide measurement of the electrical resistance of paint formulations for all electrostatic applications as well as the short circuit  current (SCI) of electrostatic applicators.
It has an SCI scale (0 to 250 microamperes) and paint resistance scales (infinity to 0.01 and 2.0 to 0.001 in megohms).

The Paint Test Meter and Probe features:

• Digital multi-scale meter with integrated Sprayability Meter.
• Matching Paint Resistance Probe.
• Gun output test leads for short circuit current (SCI).
• Certified as ASTM standard.

 

Ransburg Multifunction Electrostatic Meter - Test Equipment

Caracteristici:

This meter has two (2) scales, MΩ and kΩ that may be used for the measurement of the paint resistance.
Once the resistance of the paint is determined and found to spray successfully, measuring resistivity with this meter provides a way to duplicate conditions.
This is also important when troubleshooting problems with spray or rotational applicators.

Aplicatii

Testing and the measurement of the electrical resistance of paint formulations

• The multi-function electrostatic spray meter uses one meter to serve multi functions in electrostatic spray finishing.
• The meter can be used to measure conductivity, paint resistance, short circuit current, resistance and high voltage
• The Ransburg multi-function electrostatic spray meter uses one meter to serve multi functions in electrostatic spray finishing. The meter can be used to measure conductivity, paint resistance, short circuit current, resistance and high voltage.
• The meter is available in individual kits focused on each function or a deluxe kit, which includes accessories to perform extra functions.

De ce este important rezistivitatea vopselei?

Paint resistivity is the most important factor to determine whether the paint formulation is suitable for the electrostatic painting process.

• By definition, paint resistivity is the degree to which the coating material resists the flow of current. Coating materials with a high paint resistivity may work poorly.
• They can usually be reformulated to make them suitable. This does not mean that the resistivity should be as low as possible.
• As a rule of thumb, a resistivity of 20 to 140 MΩ-CM is suitable for most kinds of electrostatic equipment.
• The Ransburg paint resistivity meter measures the resistivity in megaohm (MΩ). To obtain MΩ-CM, as needed for the ASTM D5628 standard, the MΩ reading from the meter must be multiplied by 132 (MΩ-CM = MΩ reading x 132).

Also important: When high voltage is applied, the properties of some coating materials may change (for example metal flakes and coatings with metallic content), i.e. when measured they feature high resistivity, but have actually low resistivity when applied under high voltage.
