Description
The Tonghui TH1912A millivoltmeter with 0.1 μV resolution enables the simultaneous display of main and secondary values such as dBm, %, Max/Min via a dual VFD display - ideal for use in production lines, repair workshops, training laboratories and automated test facilities.Features
- Frequency range: 5Hz-3MHz
- Measurement voltage range: 50μV-300V, resolution: 0.1μV
- Measured value display function: 4 1/2 digits VFD, dual display: the main display shows one measured value, and the secondary display can call up other measured values at will
- Absolute value: mV, V, W, dBm, dBV, dBmV, dBμV, Vp-p
- Relative value: dB, %, Max/Min
- Software menu setting: Measure power and dBm, set source load resistance as required
- Measurement dB,%, Max/Min Reference value setting
- Setting of ground (GND), float and safety warning
- Standard RS232C interface, support for SCPI command programming
Applications
- Workbench for production lines
- Repair workbench
- Teaching laboratory
- Automated test equipment
