Autoread Breathing status light

Status light makes easier waiting for Auto Read result. More focused energy is retained for greater productivity.

Calibration reminder

Let the measurement stay on track by applying the calibration reminder progress-bar and countdown days.


Theory Visualization Calibration

Clearly and concisely illustrate information with dynamic calibration lines so calibration can be understood and performed.

Type-C USB Power Supply / transmission

Easy power supply solution. Use the USB Type-C port to connect either a USB power supply or portable power bank, and also can be for data printing.


Diverse Information

Experience switchable information of the display, from calibrated buffer values, realtime mV value or a clear streamlined mode to easily focusing on main measurement.

Graphical Menu

Easy to understand and operate quickly. Also, flexible system settings allow freely adjusting the backlight and contrast.


Calibration Traceability

Attain complete calibration traceability with access to up to 50 sets of calibration records.
