Sonel PRS-1

If you are using site insulation as a means of protection against electric shock, you should check the insulation resistance of floors and walls with an appropriate measuring instrument. PRS-1 is shaped like an equilateral triangle and has been made according to the guidelines provided in the HD 60364-6 and EN 1081 standards. The legs of the probe were made with a special rubber mix; each leg has a volume resistance of 5 kΩ or less and hardness in the range between 50 to 70 IRHD. With appropriate pressure on the probe, you will get approximately 900 mm2 contact surface area with the tested plane.

Test probes like PRS-1 are available for testing floor and wall insulation. PRS-1 is shaped like an equilateral triangle and has been made according to the guidelines provided in HD 60364-6 and EN 1081 standards. Its legs were made using a special rubber mix that ensures a minimum of 5 kΩ resistance per leg and hardness between 50 to 70 IRHD. Applying appropriate pressure on the probe will ensure 900 mm2 contact surface area with the tested plane.
