PosiTest HHD Series

What is the difference between the PosiTest HHD and the PosiTest HHD C?

The HHD is a stick-type detector that uses pulsed DC output up to $35\text{ kV}$, while the HHD C is a compact wand-style unit that uses continuous DC output up to $30\text{ kV}$.

How is the correct test voltage determined for my coating?

The instrument features an innovative Voltage Calculator that automatically computes the required test voltage when the user inputs the coating thickness, based on a selected international standard.

What is the function of the built-in certified voltmeter?

The internal certified voltmeter continuously measures and displays the exact voltage being applied at the electrode, confirming the instrument’s accuracy and ensuring compliance with inspection specifications without needing an external verification meter.

Is the PosiTest HHD Series compatible with electrodes from other manufacturers?

Yes, the detectors feature industry-standard connectors and optional adaptors that allow them to be used seamlessly with existing electrodes from major competitive brands like SPY, PCWI, and Tinker & Rasor.

What are the recommended coating thicknesses for using a high-voltage detector?

High-voltage detectors like the PosiTest HHD Series are typically used for inspecting coatings that are thicker than $250\text{ μm }(10\text{ mils})$, where a low-voltage wet sponge detector would be insufficient.
