Principle of combustible gas detector

Suitable for thickness measurement of almost all materials, such as metal, glass, plastic, rubber, etc;
High measurement accuracy and wide measurement range; Suitable for measuring the thickness of pipes;
The full range of thickness measuring probes can be used in conjunction with thickness gauges to meet multi-purpose thickness measurement applications; Multiple probe options are available, suitable for special thickness measurement applications, including coarse-grained materials such as gray cast iron and high-temperature environment measurement (temperature up to 300 ℃) applications;
Probe adaptive function: automatically matching different types of probes, automatically testing and identifying sensitivity and frequency parameters, automatically adjusting thickness gauge parameter settings, achieving measurement results;
• Power on self-test function, which helps improve measurement accuracy;
The automatic shutdown time can be set according to user habits;
• Probe zero point automatic calibration, sound velocity calibration function;
Built in sound speed for 9 different materials and editable, making it convenient for users to use;
Multiple practical measurement modes: standard measurement mode, scanning mode, difference measurement mode, average measurement mode, extreme value alarm mode, high temperature measurement mode (with high temperature probe);
Humanized design of 8 keyboard buttons, simple, convenient and fast to perform: zero point calibration, single point and two-point calibration of sound speed, and free adjustment of numerical values with directional keys;
Humanized data saving mode: data can be saved in groups, and the amount of data saved in each group can be selected, without the need to manually save measurement data, simplifying operations;
• Large capacity data storage: up to 2000 sets of data storage capacity;
USB data transfer interface, easy to connect with computer data for data export (data format. txt);
• Available in metric/imperial: Display units can be selected between millimeters and inches
