Optimization, Precision, and ROI: SES-802 vs. SES-902
Prepared by: Sichuan Weihong Technology
For: Laboratory Managers & Quality Control Professionals
In the metallurgical industry, the Carbon and Sulfur Analyzer is the gatekeeper of quality. Choosing the wrong instrument can lead to two costly scenarios: over-investing in features you don't need, or under-investing and facing bottlenecks due to limited range or frequent maintenance.
At Sichuan Weihong Technology, we offer two distinct solutions tailored to different operational scales: the SES-802 (Standard) and the SES-902 (Flagship).
This guide provides a transparent, technical breakdown to help you align your equipment choice with your laboratory’s specific testing volume, material complexity, and budget.
Before comparing models, it is essential to understand the shared DNA of our equipment. Both the SES-802 and SES-902 utilize High-Frequency Induction Combustion combined with Infrared Absorption.
· Speed: Analysis completes in <40 seconds.
· Accuracy: Unlike gravimetric methods, infrared detection minimizes human error.
· Flexibility: Capable of analyzing steel, iron, alloys, non-ferrous metals, cement, and ore.
Positioning: Cost-Effective, Stable, Standard Applications.
The SES-802 is engineered for laboratories that focus on routine quality control. If your facility primarily tests standard steel grades (e.g., carbon steel, cast iron) and prioritizes stability and low operating costs, this is your optimal choice.
Key Strengths:
· High Stability: Features a reliable pneumatic system with standard high-pressure valves to ensure zero leakage.
· Simplified Operation: The software focuses on core functions—analysis, curve monitoring, and data printing—making it easy for new operators to learn.
· Cost Efficiency: Lower initial capital expenditure (CapEx) and reduced consumable usage.
Best For: Foundries, General Steel Mills, Third-party Testing (Standard tiers).
Positioning: High-Throughput, Ultra-Low Detection, Intelligent Automation.
The SES-902 represents the pinnacle of our technology. It is designed for complex analytical environments where "trace element" detection is critical and downtime is not an option.
Key Upgrades (vs. 802):
· Dual-Range Detection: Equipped with multiple infrared cells. It can simultaneously detect ultra-low carbon (ppm level) and high carbon content without hardware adjustments.
· Automatic Cleaning: A built-in vacuum system automatically cleans the furnace head dust, significantly reducing the frequency of manual maintenance.
· Ultra-Low Drift: Optimized for analyzing high-purity metals (e.g., Superalloys, Titanium) where background noise must be minimized.
Best For: Aerospace, Nuclear Industry, Research Institutes, Special Alloy Manufacturers.
| Feature | SES-802 (Standard) | SES-902 (Flagship) |
| Primary Application | Routine QC, Standard Steel/Iron | R&D, Special Alloys, High-Throughput |
| Detection System | Single/Standard Range | Dual-Range (High & Low) |
| Low Carbon Precision | Standard (RSD ≤ 0.5%) | Ultra-High (ppm level sensitivity) |
| Cleaning System | Manual Cleaning Required | Automatic Furnace Cleaning |
| Analysis Range | Wide | Full Spectrum (Trace to High %) |
| Automation Level | Semi-Automated | Fully Automated |
| Ideal Throughput | < 100 samples/day | > 100 samples/day |
Answer these three questions to find your match:
Q1: Do you need to measure ultra-low carbon/sulfur (ppm level)?
· Yes, we test high-purity materials. -> Choose SES-902.
· No, mostly standard carbon steel. -> Choose SES-802.
Q2: What is your daily sample volume?
· High volume. We need speed and hate stopping to clean dust. -> Choose SES-902 (The auto-cleaning saves hours per week).
· Moderate volume. Manual cleaning once a shift is acceptable. -> Choose SES-802.
Q3: Is your budget strictly capped?
· Yes, we need the best value for basic compliance. -> Choose SES-802.
· No, we prioritize long-term efficiency and capability. -> Choose SES-902.
Quality control is an investment, not an expense.
· Select the SES-802 for a robust, budget-friendly solution that gets the job done reliably.
· Select the SES-902 to future-proof your lab with top-tier precision and automation.
