Hioki 0 - 30.0 V rms Digital Earth Tester With Clamp Sensors, FT6041-91

Measure ground resistance without disconnecting ground electrodes: MEC(*) function

This function augments the 3-pole method with current measurement using a clamp sensor. By measuring only current flowing to the grounding electrode you wish to measure, you can avoid the effects of other grounds. This capability can substantially reduce man-hours spent on measurement work.

Measure soil resistivity when surveying a grounding design by 4-pole method

Soil resistivity is measured as part of the grounding design process in advance of building design. Soil resistivity varies with each site’s geological properties. In this process, optimal ground locations as well as grounding electrode shapes, dimensions, and other characteristics are designed based on the assessed soil resistivity.

Built tough to withstand use at harsh sites

• Dirt, sand, and rain resistance, IP67 dust and water protection Since the Earth Tester FT6041 is designed to keep dust and dirt out of its enclosure, you can use it in the field without worrying about mud or dust. If it gets dirty, simply rinse it off with water.
• Operating temperature range -25°C to 65°C Extreme cold, extreme heat. The FT6041 won’t fail, even during extended operation.
• Drop-proof design 1 m with protector attached Withstands being dropped onto concrete from a height of 1 m
• Excellent noise resistance, Allowable ground potential: 30.0 V RMS Even in an environment where the ground potential is 30.0 V RMS, stable ground resistance can be measured.

Designed to shorten work times and reduce operator workload

• Fast measurement! Cord rewinding that doesn’t tangle or twist. The combination of fast measurement that displays measured values in just 6 seconds (3-pole method) and easy-to-use cord rewinding shortens work times.
• Insert just once thanks to 100 kΩ max. allowable resistance. High “allowable resistance of auxiliary grounding electrode” eliminates the inconvenience of needing to insert and reinsert auxiliary electrodes repeatedly in dry soil. The result is shorter work times.
• Make measurements, even on concrete. Newly designed Earth Nets Module L9846. This module is essentially an auxiliary electrode for flat surfaces in which the traditional stakes can’t be inserted. When opened, two copper nets make contact with the surface. Simply make contact and pour water over it to measure ground resistance without inserting any auxiliary electrodes into the ground.

Unique clamp sensor for tight spaces

• Earth electrodes are located at the tight spaces. On top of that, some bus bars are also thick.
• The CT9848 clamping sensor can be used to clamp those points.
• The thin, wide bore jaws allow for smooth clamping of the ground electrodes.

Wireless support - It transfers measurements to your smartphone or tablet

• Compatible with Wireless Adapter Z3210 (optional). It transfers measurements to your smartphone or tablet and allows you to quickly create reports with field photos and drawings.
• GENNECT Cross, a free app designed specifically for use with Hioki measuring instruments, lets you check and manage measurement results and create reports.
• The software provides a range of functionality that helps manage data in the field, including photographing measurement sites, placing measurement results on photographs, and saving hand written memos.
