HT Instruments T2100 Clamp for Measuring Earth Resistance Without Rods.

Description

The HT Instruments T2100 is a professional earth ground clamp meter that measures earth resistance and leakage current in a loop without requiring auxiliary rods or disconnection of the system. It is particularly useful for measuring resistance in multiple grounded systems, which saves time and improves safety for electrical installations and maintenance.

Key Features

• Measurement principle: The clamp's two jaws function independently. One jaw generates a voltage on the earth loop, and the other measures the resulting current. The meter then calculates the earth resistance based on these two values.
• True RMS measurement: The T2100 performs True Root Mean Square (TRMS) measurements, which provides a more reliable reading for distorted, non-sinusoidal waveforms that can occur in industrial electrical systems.
• RS-232 interface: An integrated RS-232 port allows the meter to connect to other HT Instruments devices, such as the MACROTESTG3, MACROEVTEST, and GSC60. This enables data transfer for saving and reporting test results on a PC.
• Data logging: The device includes an internal memory with storage capacity for up to 99 measurement values.
• User convenience: The T2100 features a large, backlit LCD display with a bargraph for easy readings in different environments. It also includes an automatic shut-off function after five minutes of inactivity and a data hold function.
• Safety and durability: The instrument is compliant with IEC/EN61010-1 standards and rated for CAT III 600V and CAT IV 300V measurements, though different vendors list varying CAT ratings, so check the specifications carefully. It has a robust protective case.
