Dial Gauge Automatic Tester Model DGT-20G


Dial Gauge Automatic Tester Model DGT-20G

When using a dial gauge, it is usually mounted on a jig for inspection. To perform its periodic
inspection, it needs a lot of processes more than the other measuring instruments and further
time-consuming troublesome works to graph the inspected results are required.
Model "DGT-20G" contributes to decrease such troublesome works extremely.
By only setting a pointer of dial gauge and just turning on a memory switch, gauge testing is
automatically made.
Everyone can use it with great ease.

 (1) Easy operation
By only setting a pointer on the scale of dial gauge and just turning on a memory switch, measured data is processed
by a micro-computer and its results are automatically printed out.
 (2) Reducing eye strain
Only fix your eyes to a pointer of dial gauge!
Since you do not read the scale of a gauge tester, measurement for a long time will not tire your eyes.
 (3) Reducing your inspection time extremely
It can reduce your inspection time from one third to one fifth shorter compared with the conventional method of
inspection since this tester has no necessity of reading, recording, and judging the error values.
 (4) High precision
Usual calibration is not necessary because of the optical glass scale capable of maintaining the stable accuracy with
less aged deterioration. Stable inspection is possible because a spindle is not a revolutionary type but a straight one.
 (5) Register function
Once the measuring range, pitch, and values for judgement are registered, speedy inspection can be done just by
calling out these items. There include the items already registered by the maker(ROM)and the ones to be originally
registered by users(RAM).
 (6) Manual mode
Measuring items can be set by manual setting. It will be effective to inspect such a gauge that you do not usually use.

DGT-20G ( example )
Applicable gauges
Dial gauge ( based on JIS B 7503 )
Special type gauge ( based on JIS B 7509 )
Lever-type gauge ( based on JIS B 7533 )
