Explanation：

Consistent with GB/T9138-1988 standards, JJG817-93 statutes and JGJ/T23-2001 technical regulations, this product is suitable for supervision of the company, quality supervision on-site sampling tests, as well as testing centers. On-site automatically assess results and print, without manual calculation.

Features:

1. The host and sensor integration design, easy to operate and efficient.(Market products are detached)

2. High-resolution LCD color screen 176*220（Market products are black and white and low-resolution）

3. Power source is 4pcs of AA alkaline batteries)

4. Non-contact metal reflection grating + reflective encoder sensing, high accuracy (Market products for ordinary transmission-type grating -opt coupler sensor)

5. Voice reported, LCD and scale readings are triple guarantee the accuracy of the data. Field work without electricity and still can get the measured results through using the scale readings. Voice reported can improve the efficiency of work at special environment. (Peer-products in the market have no voice and ruler functions.)

6. Using USB communication interface, then quickly export the computer component data (market products for the RS232 interface)

7. Easy to operate, the software set the upper and lower rebound values, the outliers can be automatically removed.

8. Test hammer using imported parts, mechanical parts machining high precision, long service life.
