Description
The FNIRSI S1 is a compact, rechargeable smart digital multimeter featuring a high-definition VA colour screen with a 9999-count dual display. It accurately measures AC and DC voltage up to 1000V, resistance, capacitance, frequency, temperature, continuity, and live wires with intelligent auto-ranging and anti-burn protection. It is an ideal diagnostic tool for students, electronics hobbyists, makers, and automotive technicians.
Smart measurement features
The meter features automatic function identification and auto-ranging to effortlessly measure AC and DC voltages up to 1000V, resistance up to 100MΩ, and capacitance up to 10mF. Additional capabilities include non-contact voltage (NCV) sensing, live wire detection, diode testing, and an audible continuity buzzer.
Display and build
Readings are presented on a high-clarity VA colour dual display with analogue bar representation, low voltage warnings, and data hold. Built from durable ABS material, the slim 135g housing also integrates a handy flashlight for working in dark enclosures.
Rechargeable power
An integrated 1000mAh lithium battery delivers portable power without requiring disposable cells. The meter charges conveniently via USB-C from any standard 5V USB charger, computer port, or power bank.
