Kyoritsu 4105A Earth Tester With Hard Case
The Kyoritsu 4105A is a precision earth resistance tester supplied with a hard 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 hard 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 rigid hard case for extra protection of the tester and its test leads during transport and storage.

Frequently Asked Questions
What is the advantage of a precision earth resistance tester?
Precision models deliver more stable readings and finer measurement resolution, enabling detection of marginal earth conditions and early signs of system degradation.
When does a facility need higher precision in earth testing?
Critical facilities—data centers, hospitals, electrical substations—rely on precision testers to monitor grounding systems and predict problems before they disrupt operations.
How does the hard case protect precision instruments during transport?
The hard case shields sensitive electronics from impacts during vehicle transport and rough handling, preserving calibration and measurement accuracy over time.
Is precision-grade testing necessary for routine building compliance audits?
Routine compliance checks can use standard testers; precision models are most valuable for trend analysis, predictive maintenance, and troubleshooting intermittent faults.
How does 2 mA low current benefit precision earth testing?
Low current preserves measurement accuracy while avoiding RCD nuisance trips, crucial when monitoring sensitive systems like medical equipment grounds or server installations.
What types of corrosive environments benefit from IP54-rated precision testers?
Coastal facilities, chemical plants, and outdoor substations face salt spray and moisture that can degrade non-sealed instruments, making IP54 protection essential for reliable long-term use.
How long is typical lead time for precision test equipment delivery?
Precision instruments may require longer lead times; contact Procure.ae for current availability and an estimated delivery date.
Do you offer equipment validation or setup support upon delivery?
Procure.ae can coordinate delivery and orientation; for formal calibration or validation, consult accredited testing laboratories.
What measurement specification defines the precision of the 4105A?
The 4105A is a precision model with the same 2 mA current as the 4102A but with refined internal design; contact Procure.ae for detailed accuracy and resolution specs.
Does the hard case model include any additional accessories?
The 4105A-H includes the hard protective case; please contact Procure.ae for a complete list of included test probes and leads.
What is the warranty coverage for precision Kyoritsu instruments?
Precision equipment typically includes comprehensive manufacturer warranty; contact Procure.ae to confirm the specific coverage and service terms.
