MT9940N Series Intelligent Electric Quantity Measuring Instrument
Product Introduction
MT9940N Series Intelligent Electric Quantity Measuring Instrument(Digital Power Meter), Can Measure The Voltage,Current,Power,Power Factor,Frequency,Electric Energy And Other Parameters ,Rich In Content,Has A Wide Measuring Range, The Preset Alarm,Latches And Communications Function.
The MT9940N Series Has All The Measurement And Display Function,Increases The Maintain Data Function,As Well As The Display Function Of Frequency And Power (Energy) These Two Parameters On The Basis Of The Original MT9800. MT9901N Increase The Limit Alarm Function Of Current And Power Based On The MT9800N. MT9940N And MT9980N Expand The Range Of Current (Maximum For 40A And 80A Respectively)Based On MT9901N,It Can Measure The Current And The Products With More Power.
Aiming At The Shortage Of Above Various Products In Small Current Measurement Accuracy (The Current Resolution For 1mA),MT9813N Increase A Small Current Range(Current Resolution Is 10uA)On The Basis Of MT9901N,It Can Be Used For Current And Products With Small Power.
These Products Can Communicate With The Host Computer Through The RS232 Interface After Increasing The Communication Adapter Board,It Can Observe Data And Set Parameters Remotely Through The Host Computer.
