HIOKI DT4223 Digital Multimeter
Pocket DMM that Prevents False Circuit Breaker Trips using Proprietary Technology

OVERVIEW

The Hioki DT4200 Digital Multimeter Series consists of a diverse array of meters ranging from professional to industrial to pocket meters, delivering a super fast response rate and safety features that take electrical testing to a higher level. The Hioki DT4223 is a pocket-sized digital multimeter featuring an innovating circuit-breaker false trip prevention function to enhance testing safety and a built-in voltage detector, ideal for electrical inspections.

CAT IV 300 V, CAT III 600 V

Introduction of voltage input protection functionality
This functionality keeps errors in instrument configuration from resulting in an electrical accident. Even if the instrument’s rotary switch is mistakenly set to the resistance function when attempting to measure voltage, placing the probes in contact with the circuit under measurement will not cause a tripped circuit breaker or electrical arcing.
