Introduction
In today’s fast-paced industrial and laboratory environments, precision and efficiency are paramount. One instrument that has revolutionized quality control processes is the Automatic Acid Value Tester. This advanced device offers unparalleled accuracy in determining the acid value of various substances, making it indispensable in industries ranging from food production to petroleum refining. At HVHIPOT, we understand the critical role this equipment plays, which is why we’ve developed the GDSZ-402 Automatic Acid Value Tester to meet the highest industry standards.
What is an Automatic Acid Value Tester?
An Automatic Acid Value Tester is a sophisticated analytical instrument designed to measure the acid number (or neutralization number) of oils, fats, and other organic compounds. Unlike traditional titration methods that require manual intervention, automatic testers:
- Perform complete analysis with minimal operator involvement
- Deliver results with superior repeatability (typically ±0.01 mg KOH/g)
- Feature intuitive touchscreen interfaces for easy operation
- Include built-in data storage and export capabilities
Key Features of Modern Automatic Acid Value Testers
The latest generation of testers, like the HVHIPOT GDSZ-402 model, incorporates cutting-edge technologies:
1. Precision Titration System
Utilizes high-accuracy burettes with resolution up to 1/10,000 mL and advanced endpoint detection algorithms.
2. Intelligent Temperature Control
Maintains optimal testing conditions with ±0.1°C stability, crucial for accurate acid value determination.
3. Multi-sample Capability
Advanced models can process up to 6 samples sequentially without operator intervention, significantly improving laboratory throughput.
4. Compliance with International Standards
Designed to meet ASTM D974, ISO 660, GB/T 5530, and other major testing protocols.
