Tentech

Tentech

Tentech is a manufacturer of electrical safety testing instruments specializing in ground resistance measurement, insulation resistance testing, and low-resistance (micro-ohm) measurement. Their instruments are designed for verifying the integrity of grounding systems, evaluating cable and motor insulation, and measuring contact and joint resistance in power infrastructure.

Tentech's product line addresses essential electrical measurement tasks encountered during installation verification, preventive maintenance, and compliance testing in industrial and utility environments. The range spans from digital earth testers to high-voltage megohmmeters and high-current micro-ohmmeters capable of accurately resolving contact and weld resistance.

Key Product Lines

• Ground Resistance Testers: Smart digital earth testers for measuring the resistance of grounding electrodes and earth bonding systems
• Insulation Resistance Testers / Megohmmeters: High-voltage instruments (up to 10 kV) for insulation testing of cables, transformers, and rotating machinery
• Micro-Ohmmeters: High-current instruments for measuring contact resistance, busbar connections, circuit breaker contacts, and weld integrity

Industries Served

Tentech instruments are used in electrical installation and maintenance, power generation and distribution utilities, industrial manufacturing plants, and electrical safety testing laboratories. Their ground resistance and insulation testing instruments are particularly relevant wherever grounding integrity and insulation quality are critical for personnel safety and equipment protection.
