This is an individual test probe from Metrel in red colouring. Other colours are also available in store.
The probe is double insulated for protection from electricity and has a 4mm connector, allowing it to be connected to any test lead that has the necessary connector. This means that despite carrying Metrel's branding, this probe is also suitable for use with devices from other manufacturers such as Fluke, Megger, Seaward and many more.
The probe conforms to BSEN61010 and is fully shrouded and insulated to HSE GS38.
