PVN Dyne Pen Surface Tension Meter Pack of 4 36 to 42 Dynes Purple

Description

Product Overview

The PVN Dyne Pen is a precision instrument designed for on‑line surface tension testing of blown film and multilayer film products. Manufactured by PVN TECHNO SYSTEMS LLP, each pen is constructed from high‑quality plastic with a retractable mechanism that protects the fine 0.3 mm tip when not in use. The set includes four pens, each calibrated to deliver measurements in the 36 to 42 dyne range, complying with European standards and ASTM D2578. The pens are colored purple for easy identification, feature a blue ink that provides clear, readable markings, and are engineered with a spring‑loaded tip that feeds fluid consistently while guarding against air contamination. With a compact size of 0.79 × 0.79 × 5.51 inches and a lightweight of just 3.53 ounces per pen, they are portable enough for field work yet robust enough for demanding laboratory environments. The product dimensions and material choices ensure durability, while the spill‑proof design minimizes waste and maintains the integrity of the test fluid throughout the measurement process.

Usage

These pens are ideally suited for printers, coaters, laminators, and any operation that requires precise control of surface tension in film, sheet, coated board, inks, coatings, or adhesives. In a production line, the PVN Dyne Pen can be used directly on the moving web to provide real‑time feedback, allowing operators to adjust formulation or process parameters instantly. In a laboratory setting, the pens serve as a reliable tool for quality‑control testing, research and development, and validation of new coating recipes. The retractable tip and spill‑proof reservoir make the pens safe for use in environments where cleanliness is critical, such as clean rooms or food‑grade facilities. Because the pens are calibrated per batch and tested on a tensiometer, users can trust the consistency of each measurement, reducing the need for frequent recalibration. The compact form factor also enables easy storage in toolboxes or on‑site kits, making them a convenient choice for field technicians who travel between multiple production sites.

FAQ

How often do I need to recalibrate the PVN Dyne Pen?

The pens are calibrated at the factory and tested on a tensiometer for each batch, so routine recalibration is not required unless the pen is dropped or exposed to extreme conditions.

Can the pen be used with any surface tension test fluid?

While the pen works best with the PVN‑specified reagent‑grade fluid, it is compatible with other standard surface tension fluids that meet ASTM D2578 specifications.

Is the pen suitable for high‑temperature environments?

Yes, the plastic housing and spring‑loaded tip are designed to operate reliably up to 60 °C (140 °F), making the pen suitable for many industrial processes.

What warranty does PVN provide?

PVN offers a one‑year limited warranty covering manufacturing defects and includes free technical support for the duration of the warranty period.

How do I clean the pen after use?

Simply retract the tip, wipe the exterior with a lint‑free cloth, and flush the tip with a small amount of distilled water or the recommended cleaning solution to remove any residual fluid.
