The Elcometer PTG8 Ultrasonic Precision Thickness Gauge (part number PTG8BDL, supplied with transducer as PTG8BDL-TXC) is the top of the range precision gauge for non-destructive measurement of material thickness on virtually any material, from one side only. The Elcometer PTG8 Ultrasonic Precision Thickness Gauge addresses the inspection need to measure or check for thinning on small, thin or intricate components where there is no access to the reverse face, and adds the data handling and analysis tools required for formal reporting.
Measurement runs from 0.15mm to 25.40mm across three modes: Echo-Echo (E-E) from 0.15 to 10.15mm, Interface Echo (I-E) from 1.65 to 25.40mm and Plastic Mode (PLAS) from 0.15 to 5.00mm, each accurate to plus or minus 0.015mm at the low end and plus or minus 0.5 percent above 3.00mm. Rate is selectable at 4, 8 or 16 readings per second. The user definable display of the Elcometer PTG8 Ultrasonic Precision Thickness Gauge can show readings, statistics including mean and standard deviation, a scan bar graph, run chart, differential mode against a nominal value, or a B-Scan cross sectional view for relative depth analysis. Calibration covers 1-Point, 2-Point, 39 preset materials, velocity and factory reset, with three programmable calibration memories and a calibration lock.
The Elcometer PTG8 Ultrasonic Precision Thickness Gauge stores up to 100,000 readings in up to 1,000 sequential or grid batches, supports user definable upper and lower limits with audible and visual pass/fail warnings, and outputs via USB and Bluetooth to ElcoMaster and ElcoMaster Mobile apps. The Elcometer PTG8 Ultrasonic Precision Thickness Gauge can be used in accordance with EN14127 and EN15317. Supplied by BAMR, South Africa's authorised Elcometer distributor.

When to use the Elcometer PTG8
The PTG8 is the top of the precision ultrasonic range, measuring material thickness from 0.15mm to 25.40mm on virtually any material. Reach for it when a thickness survey needs on-gauge data logging, scan mode and pass/fail limits, not just one reading at a time.
- 1Large on-gauge memoryIt stores up to 100,000 readings across up to 1,000 sequential or grid batches, so a full survey stays on the gauge until you sync it to ElcoMaster rather than being transcribed by hand.
- 2Sees variation across an areaScan Mode plus Bar Graph, Run Chart, B-Scan and Differential Mode let you track how thickness changes across a wall or vessel rather than reading isolated points.
- 3Flags out-of-spec at the point of measurementUser-definable upper and lower limits trigger audible and visual warnings, so a thin wall is caught while the probe is still on it, not later in the data.

Frequently asked questions
What measurement modes does the PTG8 support and what are the accuracy figures for each?
The PTG8 supports Echo-Echo (E-E, 0.15 to 10.15mm), Interface Echo (I-E, 1.65 to 25.40mm), and Plastic Mode (PLAS, 0.15 to 5.00mm). Accuracy is plus or minus 0.015mm for readings below 3mm and plus or minus 0.5% from 3mm upward in each mode.
How does the PTG8 differ from the PTG6 in terms of data logging?
The PTG8 adds data logging: 100,000 readings, 1,000 batches, sequential and grid batching, fixed batch size with batch linking, obstruct entry, alpha-numeric batch names, date and time stamp, and a batch review graph. The PTG6 has no data logging.
What display modes are exclusive to the PTG8?
The PTG8 adds selected statistics, scan thickness bar graph, run chart, readings and differential, and B-Scan cross-sectional display. The PTG6 shows readings only.
What calibration options does the PTG8 support?
The PTG8 offers 1-point and 2-point calibration, selection from 39 preset materials, factory reset, velocity calibration, calibration lock with optional PIN, test calibration, three programmable calibration memories, and a measurement-outside-calibration warning.
What are the physical specifications of the PTG8?
The PTG8 weighs 210g including batteries, measures 145 x 73 x 37mm, and operates from -10 to 50 degrees C. It uses two AA batteries giving approximately 15 hours on alkaline or 28 hours on lithium, and is impact, waterproof, and dust resistant equivalent to IP54.
Which transducers are compatible with the PTG8?
The listed compatible transducers are the TXC15M0CM and TXC20M0CM, both 1/4 inch right-angle probes with standard damping. Both are listed as suitable for thin plastics, steel, aluminium, and titanium.
