HT Instruments TL-50MKT 50 m Earth Test Lead Extension on Cable Reel, Green 2009690

The TL-50MKT extends the reach of HT Instruments earth resistance testers by 50 metres, with the cable stored on a manual reel that keeps the lead tangle-free between measurements. The green PVC insulation is flexible enough to lay out across uneven ground, while the high-purity copper conductor keeps resistance low so the extra length does not distort readings.

Highlights

• 50 m extension lead for earth resistance testing
• 4 mm safety banana plug to spade terminal
• High-purity copper conductor, flexible PVC insulation
• Manual cable reel for tidy storage and transport
• Compatible with GEO416, GEO417, GEO418, GEO419 and MACROTEST G3

In daily use

The reel pays out smoothly when you need to reach a distant auxiliary earth spike, and the spade terminal attaches directly to the rod. After the test, winding the cable back onto the reel takes seconds, so the lead is ready for the next job. The green jacket is easy to spot on site, reducing the chance of leaving the lead behind.
