Hioki 3143 Earth HiTester

DISCONTINUED ITEM

The 3143 is particularly useful for measuring the earth resistance of single rod electrodes found among aerial transmission line equipment and various types of safety box circuits, and incorporates a measurement principle that is different from that of the Earth HiTESTER 3151.

• Measure ground resistance on paved roads
• Auxiliary grounding rods not necessary
• Large digital display for easy viewing
• Soil-resistant design and superior durability
• Dimensions: 155 (6.10in) W × 98 (3.86in) H × 49 (1.93in) D mm
• Supplied accessories:MEASUREMENT CABLE 9265 (black 1 m (3.28 ft), red 20 m (65.62 ft), one each; CABLE WINDER 9216 × 1), LR6(AA) alkaline batteries × 4, CARRYING CASE 9338 × 1
