TOOLTOP ET72 Handheld Signal Generator – Professional 4-20mA 0-10V Process Calibrator & PWM Generator

Overview

The TOOLTOP ET72 is a high-precision, multi-function signal generator designed for field engineers and lab technicians. It bridges the gap between DIY tools and expensive industrial calibrators. Whether you need to simulate a temperature sensor for a PLC input or debug a motor controller (VFD), the ET72 provides a stable, adjustable signal with a clear, real-time color waveform display.

Key Features

• Dual Functionality: Capable of both Outputting (Simulating) and Inputting (Measuring) signals simultaneously.

• Industrial Standard Support: Full support for 0-24mA current loops (active/passive) and 0-24V voltage signals.

• PWM & Frequency: Perfect for testing stepper motor drivers and cooling fans with adjustable duty cycles and frequencies.

• Visual Real-Time Curve: High-definition color screen displays signal trends, making it easy to spot fluctuations or noise.

• Modern Power: Built-in 3000mAh lithium battery with USB Type-C charging for long days in the field.

Technical Specifications

Why Choose ET72 for Industrial Work?

• PLC Debugging: Simulate a 4-20mA pressure transmitter to test your PLC logic without needing the actual sensor.

• VFD Tuning: Send a 0-10V signal to a Variable Frequency Drive to test motor speeds.

• Portable & Rugged: Compact enough to fit in a pocket, with a durable casing meant for factory environments.
