• True RMS industrial multimeter
• 50,000-count color display (320 x 240)
• Logging function with trend capture for easy review of data
• Bluetooth connectivity for use with the Techni-Pro iOS app
• Peak capture (record transients as fast as 250µs)

The Techni-Pro TNP388 is a true RMS, professional-grade industrial multimeter. It provides users with a wide range of advanced features including data logging with trend capture, a low pass filter, 4-20mA process loop measurements, and much more. And with a 50,000 count, 320 x 240 color display, the TNP388 makes results easy to see.

The Techni-Pro TNP388 offers exceptional performance, as well as considerable savings compared to many other manufacturers.

With a 50000 count display, data logging, graphical trend display, color screen, and more, the TNP388 is hard to beat.

The TNP388 enables very precise measurements, capable of measuring extremely small levels of voltage and current.

Minimum resolutions are as follows:

• DC voltage: 0.001mV (±0.05% +20)
• AC voltage: 0.001mV (±0.3% +25 @ 50/60Hz)
• DC current: 0.01µA (±0.1% +20)
• AC current: 0.01µA (±0.6% +25 @ 50/60Hz)

The MAX MIN Record mode captures minimum, average, and maximum input values. When the input goes below the recorded minimum value or above the recorded maximum value, the Meter beeps and records the new value, as well as the elapsed time since the recording session was started. The MAX MIN mode also calculates an average of all readings taken since it was activated.

This mode is ideal for recording power supply surges, inrush currents, and finding intermittent failures.

The TNP388 not only records data but can also display trends in an easy-to-read, graphical format. Trend data can also be zoomed in and out of.

The TNP388 is also capable of displaying voltage as a dB value, either relative to 1 milliwatt (dBm), a reference voltage of 1 volt (dBV), or a user-selectable reference value.

The TNP388 can be used to make 4-20mA loop measurements, displaying current as a percentage.

• 0mA = -25%
• 4mA = 0%
• 20mA = 100%
• 24mA = 125%

This meter features Bluetooth connectivity and can communicate wirelessly with the free Techni Pro iOS app. While using the app, it is possible to send data directly from the meter to your device, as well as store measurements and much more. Saved data can also be renamed for easier future reference.
