ZBL-T720 portable slab thickness gauge using transmitting and receiving probes on opposite faces of concrete slabs and walls.
Overview
The ZBL-T730 ZBL-T720 Slab Thickness Gauge is wireless. The receiving probe has built-in direction indicators for real-time positioning and smart navigation; the host and receiving probe are wirelessly connected, freeing users from cables. Its ergonomic design pairs the probe with extension rods so testers need not bend or squat; a flexible universal joint connects rod and probe. It supports Chinese input for building/floor/unit numbers, on-site photo logging of point locations for paperless testing, and wireless real-time upload to the inspection management system. It is mainly used to measure the thickness of slabs, shear walls, beams, columns and other concrete structures and non-ferromagnetic media.
Applications

FAQ
Q1: What standards does the ZBL-T720 Slab Thickness Gauge comply with?
A1: The ZBL-T720 Slab Thickness Gauge is designed and manufactured in accordance with relevant Chinese national (GB) and transport industry (JTG) standards, as well as applicable ASTM and AASHTO international standards. A calibration certificate traceable to national standards is provided with each unit.
Q2: How often should the ZBL-T720 Slab Thickness Gauge be calibrated?
A2: We recommend annual calibration by authorized technicians or by iRoad after-sales service center. For high-frequency laboratory use, semi-annual calibration is advised. The instrument is supplied with a factory calibration certificate.
Q3: What is the lead time and do you provide training?
A3: Standard units are usually shipped within 7-15 working days. Custom configurations may require 20-30 days. iRoad provides on-site installation, commissioning and operator training for major equipment; remote video guidance is available for standard laboratory instruments.
