Probe for measuring the resistance of floors and walls
If 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.
