Atomfair-DRH586 Integrated Digital Rebound Hammer
Product Overview
Product Applications
Key Features
-
Independently developed in line with international standards for rebound testing of concrete compressive strength, with complete independent intellectual property rights.
-
Integrated structural design: The main unit and sensor are organically integrated into one, no connecting wires required, easy to carry and low failure rate. The digital display module can be combined with any mechanical rebound hammer produced by Atomfair, easy to install and save repeated purchase costs.
-
Equipped with OLED LCD screen and touch buttons, intuitive and convenient operation, sensitive response and not easy to age.
-
Unique automatic recording function effectively improves measurement efficiency.
-
Adopts non-contact photoelectric sensor, which completely avoids mechanical wear, poor contact and other defects easily occurring in potentiometer or other contact sampling methods. It has the advantages of high precision and long service life, and retains the mechanical pointer scale for double reliability guarantee.
-
Built-in rechargeable lithium battery, continuous working time over 10 hours after full charge, meeting long-term on-site testing needs.

Important Notes
The device requires periodic calibration to maintain the specified anvil rebound value of 80 ± 2 and sampling indication consistency within ±1. The internal lithium battery must be recharged at least every six months during storage to prevent over-discharge damage.
- Calibration Specification: The rebound hammer's anvil calibration must be verified and adjusted to a rebound value of 80 ± 2 to ensure measurement accuracy.
- Battery Storage Procedure: Recharge the internal lithium battery every six months when the device is stored for extended periods to avoid irreversible capacity loss.
- Sampling Consistency Requirement: The digital output sampling value must not deviate from the vernier reading by more than ±1 unit during use.
How does the digital sampling accuracy of the Atomfair-DRH586 compare to its mechanical vernier scale?
The digital output sampling value differs by ≤ ±1 from the vernier reading, ensuring high consistency. The instrument retains the mechanical pointer scale for double reliability, allowing operators to cross-verify the digital reading.
Can the Atomfair-DRH586 digital display module be retrofitted to an existing Atomfair mechanical rebound hammer?
Yes, the digital display module is designed to be combined with any Atomfair mechanical rebound hammer. The integrated structural design allows easy installation without connecting wires, saving the cost of purchasing a separate unit.
What is the battery life and charging requirement for the Atomfair-DRH586?
The built-in rechargeable lithium battery provides over 10 hours of continuous operation after a full charge. For long-term storage, it is recommended to recharge every six months to prevent battery damage from over-discharge. The charger is included (5V 1A).
The Atomfair-DRH586 Integrated Digital Rebound Hammer combines a non-contact photoelectric sensor with a mechanical pointer scale for dual-reliability rebound testing, delivering a nominal kinetic energy of 2.207J and an anvil calibration rebound value of 80±2. Its integrated design eliminates connecting wires, while the 200-component data storage and USB2.0 interface support efficient on-site compressive strength assessment of ordinary concrete.
Positive
- Non-contact photoelectric sensor: Eliminates mechanical wear and poor contact issues common with potentiometer-based sampling, providing high precision and extended service life while retaining a mechanical pointer scale for dual reliability.
- Integrated design with long battery life: The main unit and sensor are integrated without connecting wires, reducing failure rates and simplifying portability. The built-in rechargeable lithium battery supports over 10 hours of continuous operation, suitable for extended field testing.
Trade-offs
- Requires periodic battery maintenance: If unused for extended periods, the internal lithium battery must be recharged every six months to prevent damage from over-discharge, adding a maintenance routine for long-term storage.
- Limited to rebound testing applications: The device is specifically designed for non-destructive compressive strength testing of ordinary concrete and is not suitable for other material types or strength assessment methods, restricting its use to this application scope.
