Electronic thickness tester

Introduction

An electronic thickness tester is an instrument used to measure the thickness of the materials, such as the films, the sheets, the paper, the textiles, the coatings, and the other flat materials, and it is used in the quality control and the testing in the packaging, the printing, the textile, the coating, and the many other industries. The electronic thickness tester measures the thickness by the contact or the non-contact methods, in which a probe or a sensor measures the distance between the two surfaces of the material; the contact method uses a measuring probe that contacts the material, and the non-contact method uses the optical, the ultrasonic, or the other sensors, and the tester provides the thickness, expressed in micrometers or millimeters, with a high resolution and accuracy, and it displays the values, with features such as the data logging and the statistical analysis; the electronic thickness tester is used for the measurement of the thickness of the films and the sheets, for the measurement of the thickness of the paper and the board, for the measurement of the thickness of the coatings and the platings, for the measurement of the thickness of the textiles and the nonwovens, for the quality control, for the incoming inspection, and for many other applications, and it is available as the handheld and the benchtop instruments, with the various measuring ranges and the resolutions; the electronic thickness tester is an essential instrument for the thickness measurement. Electronic thickness testers are used in the packaging industry, in the printing industry, in the textile industry, in the coating industry, and for many other applications. With their thickness measurement, electronic thickness testers are essential for the quality control.

FAQ

Q1: What testing scenarios is this tester mainly applied to?

A: The electronic thickness tester measures material thickness with micron-level accuracy for plastic films/sheets (ISO 4593), paper/board caliper (TAPPI T411, ISO 534), textiles (ISO 5084, ASTM D1777), rubber/O-rings (ASTM D374), metal foils, PCB substrates, battery separators, and packaging films. A specimen is placed between a flat anvil and a parallel presser foot of specified area under controlled pressure (critical for compressible materials: too much pressure under-measures foams/textiles). Digital displacement sensor reads the gap. Range 0-25 mm typical, resolution 0.001 mm, accuracy +/-0.001-0.005 mm.

Q2: What standards does the tester comply with?

A: Complies with ISO 4593 (plastic film thickness), ISO 5084/ASTM D1777 (textiles), ISO 534/TAPPI T411 (paper caliper), ASTM D374 (electrical insulation/rubber), DIN 53370, and GB/T standards. Hardware meets accuracy (+/-0.001-0.005 mm), repeatability (+/-0.001-0.002 mm), parallelism (<0.002 mm), and pressure accuracy. For ISO 17025, calibrate with gauge blocks traceable to national standards, maintain as-found/as-left records. Presser foot area and pressure are standard-specific (paper 100 kPa, textiles 0.5-20 kPa).

Q3: What is the warranty period for the whole tester and key components?

A: Whole tester covered 12-24 months (some 3 years). Digital indicator battery (1-2 years), anvil/foot (wear, scratch with abrasive samples), and calibration gauge blocks (wear if mishandled) are consumables. Damage from dropping, abrasive scratches, over-travel sensor damage, or unauthorized repair is excluded. Digital indicator/LVDT lasts 5-10 years; stand/anvil 10-20 years. Low-maintenance instrument.

Q4: Is this device difficult to operate? Is professional training required?

A: Very simple: zero with no specimen, place sample flat on anvil, lower foot gently, wait for stabilization (1-5 sec for creeping materials), read thickness. No professional training needed. Key points: calibrate/zero daily, use correct pressure per standard (critical for foam/rubber/textile), measure at 5-10 points for films (report average/min/max), clean anvil/foot between samples. Safety: pinch hazard from moving foot, sharp samples (foil/glass), abrasive samples can scratch precision surfaces (clean after use, consider dedicated tester). Do not use abrasive cleaners on anvil/foot.

Q5: What is the typical lead-time for order delivery?

A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.

Q6: Is regular calibration required? What is the recommended calibration cycle?

A: Calibrate every 6-12 months with certified gauge blocks at multiple points across range, plus parallelism and repeatability. Routine: zero before each use, single-point gauge block verification daily/weekly. For high-accuracy 1 um work, calibrate quarterly and control temperature at 20 +/-1 C (thermal expansion affects um-level readings). Gauge blocks themselves accredited recalibration every 1-3 years. Pressure (if adjustable) verify annually with force gauge.

Q7: Are supporting consumables universal?

A: Gauge blocks universal (Mitutoyo, Mahr, correct grade 0/1/2). Batteries standard. Presser feet/anvils instrument-specific (OEM or certified compatible). Lens paper and cleaning solvent universal. Long-term cost very low: batteries annually, gauge block recalibration 1-3 years, occasional foot replacement if scratched.

Q8: Can I customize parameters or supporting accessories?

A: Customization includes range (0-5 mm thin film high-res, 0-10/25/50 mm general), resolution (0.001 mm high-precision vs 0.01 mm QC), presser foot (area 10-1000 mm2, material steel/carbide/ceramic), pressure (fixed per standard or adjustable 0.1-100 kPa), operation (manual lever, motorized, pneumatic), form factor (bench or portable handheld), features (data output RS232/USB/Digimatic for SPC, go/no-go alarms, averaging, thermal compensation). Accessories: gauge block set, extra feet, specimen cutters, heavy stand, IQ/OQ/PQ, certifications (CE, ISO 9001, IEC 61010).

Q9: Does the purchase include on-site installation and commissioning service?

A: Standard delivery includes gauge, stand, anvil, foot, power/battery, manual (gauge blocks not included). On-site installation not required (unbox, zero, calibrate, use). Training available at additional cost. For GMP/motorized systems, on-site IQ/OQ recommended. Always zero and verify with gauge block before first use.

Q10: What types of samples are compatible with this equipment?

A: Compatible: plastic films/sheets, rubber sheets/O-rings/gaskets, paper/board, textiles/carpet/leather, metal foils, PCB/substrates, battery separators, dielectric films. Not compatible: liquids/powders/pastes, highly compressible foams without specified low pressure, very rough/uneven surfaces (foot bridges peaks), curved/3D parts without fixture, samples beyond range, or highly abrasive materials that damage foot (use sacrificial layer or dedicated tester). For films measure 5-10 points. For paper condition at 23 C/50% RH. For very thin films (<10 um), ensure cleanliness (dust causes errors).
