Product Introduction

When Hydrogen Testing Needs to Distinguish Different Hydrogen States

Hydrogen introduced during welding and other metal-processing operations can remain in materials and may contribute to hydrogen-related embrittlement or cracking. For laboratories and quality teams, the testing challenge is therefore not simply obtaining a hydrogen reading. Different inspection tasks may require the determination of diffused, residual, or total hydrogen, while welding samples may also require a different analysis time from routine metal testing.

Our Solution:

The PENY HUNO R3Hs Diffused Hydrogen Elemental Analyzer is designed to support these different hydrogen-analysis requirements in one testing system. It can determine diffused hydrogen, residual hydrogen, and total hydrogen in various metals, while also supporting total hydrogen analysis in iron-based alloys.

For welding-related testing, the analyzer typically completes an analysis in 15–30 minutes. Its 0.5–1000 ml/100g analysis range, 10-point gas standard sample calibration, and selectable ppm or ml/100g result units give laboratories a practical setup for different hydrogen-content levels and reporting requirements.

For buyers, this means the same analyzer can support welding-related diffused hydrogen testing as well as other metal hydrogen analysis tasks, reducing the need to select a separate instrument simply because the hydrogen measurement requirement changes.

Technical Specifications

Calibration and Result Management

10-Point Gas Standard Sample Calibration

The HUNO R3Hs uses a 10-point gas standard sample calibration method intended to cover its stated analysis range of 0.5–1000 ml/100g. This provides a calibration setup for laboratories working with different hydrogen-content levels rather than limiting testing to a narrow concentration range.

Flexible Result Reporting

Test results can be output in ppm or ml/100g, allowing laboratories to select the unit that matches their reporting procedures or project requirements.

Searchable Test Records

The analyzer provides searchable data storage and analysis-result evaluation. Previous measurements can therefore be located when laboratory personnel need to review historical results or check earlier test records.

Pre-Stored Sample Weights

Sample weights can be pre-stored in the system, helping operators manage the measurement workflow when performing routine analysis.

Troubleshooting Guide

1. “Collector connection failed, communication interrupted”

Recommended action: Unplug the data cable from the back of the computer and reconnect it after 2 seconds.

2. “Collector connection failed” appears when opening the analysis software

Recommended action: Check whether the power switch is turned on and whether the computer data cable is securely connected.

3. “Electronic balance connection failed” appears when opening the analysis software

Recommended action: Check whether the electronic balance is turned on, whether the connection between the balance and computer is secure, and whether the settings under Weight Processing → Configure Balance are correct.

Customer Cases

Institute of Metal Research, Chinese Academy of Sciences

The Institute of Metal Research, Chinese Academy of Sciences, requires high-precision carbon, sulfur, oxygen, nitrogen, and hydrogen analysis to support research across multiple new material fields. After communication and an on-site investigation, the institute purchased one carbon sulfur analyzer and one OHN analyzer from PENY. After the instruments were delivered, installed, and adjusted at the institute, the customer expressed high appreciation for the performance of both analyzers.

Wafangdian Bear Group

Founded in 1938, Wafangdian Bear Group produces more than 20,000 specifications of bearing products with various precision levels. With the development of its business, the company needed to meet the requirements of the domestic high-end equipment manufacturing industry. After contacting PENY and visiting our factory, the customer conducted multiple rounds of testing and ultimately purchased a carbon sulfur analyzer from PENY.

FAQ

Q: We mainly test welding samples. Is the HUNO R3Hs designed for this type of testing?

A: Yes. The HUNO R3Hs is specifically suited to diffused hydrogen analysis related to welding samples. It supports testing based on ISO 3690 and AWS A4.3, and welding samples typically require 15–30 minutes for analysis.

Q: Why would we need a dedicated diffused hydrogen analyzer instead of a general hydrogen analyzer?

A: Diffused hydrogen testing has specific requirements for sample handling, calibration, and test procedures, particularly for welding-related applications. The HUNO R3Hs uses 10-point gas standard sample calibration and is designed around ISO 3690 and AWS A4.3, making it suited to standardized diffused hydrogen testing rather than simply measuring hydrogen content as a general elemental analysis task.

Q: Our laboratory may need to test more than just diffused hydrogen. Can this analyzer cover other hydrogen measurements?

A: Yes. In addition to diffused hydrogen, the HUNO R3Hs can be used for rapid determination of residual hydrogen and total hydrogen in various metals. It can also determine total hydrogen in iron-based alloys, giving laboratories broader hydrogen testing capability when different sample requirements arise.

Q: If our laboratory needs to report results in different formats, do we have to convert the data manually?

A: The HUNO R3Hs supports result output in either ppm or ml/100g, so laboratories can select the reporting unit that fits their testing requirements.

Q: What is included when we purchase the analyzer?

A: The standard configuration includes the host machine, analysis software, computer, and electronic balance. A water cycle system and standard attachment package are available as optional configurations, depending on the laboratory's setup and testing requirements.
