Meter Relays in ±1.5% Class
for Advancing Power Saving and Automation
Hioki Meter Relays are industrial 1-channel devices to assist in energy saving
and automation implementations. The 2104 series are 1-channel ±1.5% class meter
relays featuring a sensitive 1 µA, 10 mV DC movement and a customizable scale.

Key Features
• Ultra sensitive 1 µA, 10 mV DC movement
• Includes a display lamp to illuminate movement at a glance
• Relay action delays circuit closure upon power on
• Both power circuitry and relay built-in
*H-type: Lamp lights up and output relay contact operates at deflection of the needle to the right of the setting needle
*L-type: Lamp lights up and output relay contact operates at deflection of the needle to the left of the setting needle
*HL-type: Provides functionality of both H- and L-type models
