Probe for measuring the resistance of floors and wallsIf workplaces within a property are insulated to protect against electric shock, the insulation resistance of floors and walls must be checked with a suitable meter using a probe designed for this purpose.
PRS-1 is shaped like an equilateral triangle and was manufactured according to the standards HD 60364-6 and EN 1081.
A suitable rubber compound was used to manufacture the probe feet - the contact resistance of a single foot is no more than 5 kO and the hardness is in the range of 50 to 70 IRHD.
With appropriate pressure on the probe, such a design solution ensures approx.
900 mm2 of contact with the test plane.
