Beijing Times TT220 Integrated Coating Thickness Gauge (Magnetic)
Tianjin Huayin Construction Instrument Technology Co., Ltd. and Tianjin Zhibo Lian Testing Instrument Sales Co., Ltd. mainly operate thickness gauges for various purposes, including thickness gauges for coatings on metals, plastics, wood, concrete, and glass fibers, as well as thickness gauges for fire-resistant coatings on steel structures and waterproof materials.

The TT220 coating thickness gauge adopts the magnetic thickness measurement method, which can quickly, non destructively, and accurately measure the thickness of the coating on ferromagnetic metal substrates.

It can be widely used in manufacturing, metal processing industry, chemical industry, commercial inspection and other testing fields. Due to its small size and integrated probe, this instrument is particularly suitable for on-site engineering measurements.
The main functions of TT220 coating thickness gauge are:
Zero point calibration and two-point calibration can be performed.
Basic calibration can be performed on the measuring head.
There are five statistical measures: Mean, Max*** Minimum value (MIN), number of tests (NO), standard deviation (S.DEV).
Can store and statistically calculate 15 measurement values.
There are two measurement methods: Continuous measurement method and Single measurement method.
It has an automatic shutdown function.
Delete function: Delete single suspicious data that appears during measurement, or delete all data in the storage area for new measurement.
There is a buzzing sound during the operation process.
There is an undervoltage indication function.
There is an error prompt function.
