Kyoritsu 4105A Earth Tester With Soft Case
The Kyoritsu 4105A is a precision earth resistance tester supplied with a soft case, built to IEC 61010-1 and rated IP54 for dust and drip protection. It uses a 2 mA measuring current so earth resistance tests do not trip the circuit's earth leakage breaker.Overview
The Kyoritsu 4105A earth tester delivers precision two-wire earth resistance measurement in a small, shock-resistant body, and it can be worn around the neck for one-person testing. The soft case protects the tester and its accessories between field visits.
Key Features
- Precision measurement plus a simplified two-wire test mode with neck-strap operation
- Automatic warning when auxiliary earth spike resistance exceeds tolerance
- Dust and drip proof to IEC 60529 IP54 for outdoor and site work
- Built to IEC 61010-1 safety standard with earth voltage measurement capability
- 2 mA measuring current avoids tripping earth leakage breakers under test
- Test leads for the two-wire measuring system supplied as standard accessories
- Small, lightweight and shock-resistant case for frequent field use

FAQ
Q: What does the Kyoritsu 4105A measure?
A: It measures earth (ground) resistance and earth voltage on electrical installations, reading the result directly from its analog scale.
Q: Why does the tester use a 2 mA measuring current?
A: The low 2 mA current lets you carry out earth resistance tests without tripping the earth leakage circuit breaker protecting the circuit under test.
Q: What case does this version include?
A: This SKU ships with a soft carrying case, keeping the tester lightweight and easy to carry between test locations.

Frequently Asked Questions
How does a precision earth tester improve maintenance decision-making?
Stable, repeatable readings enable tracking earth resistance trends over time, helping maintenance teams decide when to replace degraded earth electrodes before failure occurs.
What electrical systems require precision earth monitoring?
Lightning protection systems, large motor installations, cable trays, and sensitive electronic equipment grounds all benefit from precision baseline data and trend analysis.
Can technicians use the soft case version for high-frequency testing rounds?
Yes, the soft case remains protective while reducing weight for technicians conducting daily or weekly earth checks across multiple locations within a facility.
How does low-current testing (2 mA) support test repeatability?
Low current minimizes interference from existing fault currents and protective device sensitivities, ensuring consistent readings across different test times and conditions.
Are precision testers necessary for small office or retail sites?
Standard testers typically suffice for annual compliance checks; precision models are warranted when detailed diagnostics or trend data are required.
What advantages does IP54 protection offer in humid GCC climates?
IP54 sealing prevents moisture and salt spray from reaching internal electronics, maintaining accuracy and extending instrument life in coastal and high-humidity areas.
What lead times should I expect for precision test equipment orders?
Precision instruments may have longer availability windows; please contact Procure.ae to check stock and request a delivery date.
Can Procure.ae provide setup guidance for precision testing procedures?
Procure.ae supplies the equipment and basic orientation; for detailed testing procedures and methodology, consult your electrical standards or a qualified consultant.
What distinguishes the 4105A from the standard 4102A model?
The 4105A offers refined precision measurement over the 4102A while maintaining the same 2 mA test current; contact Procure.ae for detailed specifications.
Is a soft case sufficient for daily mobile use?
Yes, the soft case provides adequate protection for technicians carrying the tester between nearby test points and routine inspections within a facility.
What warranty options are available for precision earth testers?
Contact Procure.ae to confirm Kyoritsu warranty terms, coverage limits, and any extended protection plans available for the 4105A.
