96*96mm Marine Digital Tachometer One Channel Passive Relay 2
Switch Output
1. Product Description:
Series of WD-9S Single-phase rpm meters are used for measuring
and monitoring the power distribution system. This series of meter
can measure rmp in power distribution or other applications.
It combines the measurement, the analysis and the operation
together, makes the information become clearer, and the operation
become easier.
