{"product_id":"et-1020kw","title":"ET-1020kW","description":"\u003cp\u003eThe ET-1020kW digital earth tester allows for the measurement of Earth Resistances and Soil Specific Resistivity, and also the spurious voltages caused by parasitic voltages present in the soil.\u003c\/p\u003e\n\u003cp\u003eThis equipment is suitable for fast and easy measurement of the grounding resistance in house and industrial buildings, hospital installations, lightning rods, antennas, substations, etc. Soil resistivity measurement allows for soil stratification in order to optimize the most complex grounding systems engineering.\u003c\/p\u003e\n\u003cp\u003eIts state-of-the-art system of active and passive filters provides it with high immunity to electric interferences, making it possible to obtain reliable measurements even in the presence of spurious voltages, such as the ones that can be found in some urban areas and near primary substations.\u003c\/p\u003e\n\u003cp\u003eA 1,470 Hz internal generator injects alternated current on the soil through an auxiliary rod. The voltage generated over the earth resistance is measured by the apparatus, and the resistance value is evaluated. The test current is automatically regulated.\u003c\/p\u003e\n\u003cp\u003eIt has an audible signal which advises the operator when the generated current is not enough to carry out reliable measurements. Due to the fact that it may not be noticed, this alarm also prevents further testing.\u003c\/p\u003e\n\u003cp\u003eBecause of its wide range of measurement (from 0.01 Ω up to 20 kΩ), this equipment allows for reliable testing in all kinds of soils, including those that offer very high resistivity. The use of this instrument is very simple, it has a high-visibility 3½ - digit display with direct readings, even under sunlight.\u003c\/p\u003e\n\u003cp\u003eThis earth tester is supplied with a rechargeable internal battery. The smart charger is microprocessor-controlled, and can be powered from a 12 V car battery (or a similar one).\u003c\/p\u003e\n\u003cp\u003eIt has a sturdy, easy and safe to carry cabinet, with IP65 protection level. It is suitable to work under adverse geographical and environmental conditions, with extreme temperatures in cold or tropical regions and in high mountain areas, showing a reliable performance in the field.\u003c\/p\u003e","brand":"tinsley.co.uk","offers":[{"title":"Default Title","offer_id":57383068369231,"sku":null,"price":0.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1009\/2088\/5583\/files\/tinsley_ET-1020kW.jpg?v=1775124817","url":"https:\/\/tinsley.co.uk\/products\/et-1020kw","provider":"Tinsley Instrumentation Ltd","version":"1.0","type":"link"}
