Description:
The GT821F coating thickness gauge is a magnetic instrument with a wide range of applications. Its technical parameters conform to national standards.
Main Features:
● Magnetic thickness measurement method is used to measure the thickness of the non-magnetic covering layer on the magnetic metal matrix;
● Can quickly measure the coating and display the value;
● Can be calibrated using a variety of methods such as single point calibration and two-point calibration and five-point calibration;
● Negative display function to ensure the accuracy of zero point calibration of the instrument and improve the test accuracy;
● The operation process has a buzzer prompt, red light and green light prompt;
● The test reaction rate can be maintained 1 to 2 times per second
● Two shutdown modes: manual shutdown mode and automatic shutdown mode;
● Battery voltage indication: low voltage prompt;
● Micro-power design, less than 10 microamps of current in standby mode;
● Measurement method: F magnetic induction.
● Bluetooth function, USB connection.
● Storage function, menu operation
● Backlight dot matrix display, red and green LED indicator, buzzer
