TT270 Coating Thickness Meter

Introduction

 

The Times TT270 thickness gauge is a portable measuring instrument, which can measure the thickness of coating and coating rapidly and precisely without damage.It can be used in both laboratory and engineering field.Through the use of different probe, can meet the needs of a variety of measurement.Scope of era TT270 thickness gauge using both the magnetic and eddy current thickness method, measuring magnetic metal substrate condition (such as steel, iron, alloy and hard magnetic steel, etc.) on the magnetic coating thickness (such as aluminum, chromium, copper, enamel, etc.), rubber, paint and nonmagnetic metal substrate (such as copper, aluminum, zinc, tin, etc.) on the conductive layer thickness.

 

TT270 Coating Thickness Meter

Character and function

Using both magnetic and eddy current thickness method, and F type measuring head without damage to the measurement of magnetic metal basic body of magnetic coating thickness (such as steel, iron, zinc alloy and hard magnetic steel, aluminum, chromium, copper, rubber, paint, etc.), and N type measuring head without damage to the measurement of non-magnetic thickness of the conductive coating on metal substrates (such as copper, aluminum, zinc, tin and other metal oxide film of paint, rubber, plastic, etc.)

Can use 6 kinds of measuring head / 90 ° F400, F1, F1, F10, N1, CN02

Two measurement methods: CONTINUE and SINGLE

Two ways of working: DIRECT and group (APPL)

There are five statistics: MEAN, larger (MAX), MIN, number of tests (NO.), and standard deviation (S.DEV).

Two methods can be used to calibrate the instrument

Chinese and English menu display, operation more intuitive and convenient

Liquid crystal display has backlighting function

It can store 640 data

With delete function, delete single or all data measured

Print function

With integrated printer, easy to use

Power supply undervoltage indication

The operation process is beeping (single measurement method)

Error message function

Manual and automatic shutdown functions
