Product Introduction

The TOMZN TOB1-100M is a smart digital meter designed for real-time monitoring of single-phase electrical parameters. It measures AC voltage (80–300V), current (0–100A), active power (0–30000W), frequency (45–65Hz), power factor (0.00–1.00), and bi-directional energy (0–99999 kWh, unlimited in the app). The meter features a high-visibility LCD display and supports Wi-Fi connectivity for remote monitoring via a dedicated app. Compatible with Alexa and Google Assistant, it allows voice control and seamless integration into smart home systems. The device offers 1% accuracy (±2 digits) and a sampling frequency of 2 times per second. It mounts on a standard 35mm DIN rail (C45) and has compact dimensions of 54×48×80 mm. Ideal for residential energy management, solar PV monitoring, and cost allocation.
