Elcometer PTG8, Precision Thickness Gauge


Elcometer PTG8, Precision Thickness Gauge

Product Description

The PTG8 is the top of the range gauge with all the features and functionality necessary for measuring, with precision, material thickness on virtually any material.

With a user definable display, users can choose to view readings, statistical information, bar graph together with the highest (Hi); lowest (Lo); and average (x); reading or a run chart; a trend graph of the last 20 readings.

Measurement Mode

In Scan Mode, readings can be taken at a rate of 16Hz (16 readings per second) over a large surface area. When the transducer is lifted off the surface, the average, lowest and highest thickness values are displayed.

Calibration Options

The PTG8 allows users to store into memory up to three calibrations. Once saved the user can select a calibration without the need to re-calibrate the gauge, ideal for users who are measuring a variety of materials or thicknesses. Using the gauge’s alpha-numeric function, calibration memories can be re-named to suit the calibration setting.

Display Modes

The PTG8 has user definable upper and lower limits with audible and visual pass/fail warnings. Limits can be set for individual readings or for each batch. If a measurement is taken which falls outside set limits, the reading value and the limit icon turns red, the red LED flashes and the alarm beeps.

The PTG8 has Differential Mode; once a user defined nominal thickness value is set, the gauge displays the measured thickness together with the variation from the set nominal value thus indicating areas of the material which are thinner or thicker than expected.

The PTG8 offers B-Scan, a time based, cross sectional 2 dimentional graphical view of the material under test, ideal for relative depth analysis. The zoom of the B-Scan reading can either be set to automatic or can be defined by the user to focus on areas of interest.

Data Logging

The PTG8 can store 100,000 readings in up to 1,000 sequential or grid type batches. Using grid batching, readings are stored in a spreadsheet type format. The Obst feature, allows the user to record an obstruction within the grid.

Data Output

Compatible with ElcoMaster®, PC & Mobile Apps, readings can be downloaded via USB or Bluetooth® to PC, iOS or Android™ devices for further analysis and reporting.
