Rs. As per Client Get Quote

The TD1250 is a high-precision instrument designed to accurately simulate AC and DC standard resistances. It is ideal for calibrating grounding resistance testers and other AC/DC low-resistance measurement instruments. Additionally, TD1250 functions as a reliable AC/DC ammeter, supporting accuracy verification tasks such as maximum allowable error testing, alarm error verification, and current setting accuracy validation as required by industry calibration standards.

Key Features

Simulates both AC and DC standard resistances with high accuracy.
Suitable for calibration of earth resistance testers and low-resistance instruments.
Works as a precise AC/DC ammeter with scalable measurement accuracy.
Meets measurement requirements for error testing and calibration compliance.
Supports full automation and computer communication via RS-232 interface.
Stable performance with temperature and humidity tolerance suitable for laboratory and field environments.
