MINSAMP Sampler Probes
MINSAMP Steel & Slag Samplers
Disposable steel and slag samplers for chemical analysis. The probe is immersed in liquid steel; steel flows into a sealed metal mould and solidifies to form a lollipop or disc sample for spectrometric analysis. Available in single-chamber (steel only) and double-chamber (steel + slag) designs.

| Analysis Compatible | OES spectrometer, XRF |
ULC Probes — Ultra Low Carbon
Specialist samplers for ultra-low carbon (ULC) steel grades — IF steel, HSLA, electrical steel. The ULC probe uses a sealed sampling system to prevent atmospheric carbon pick-up, ensuring accurate analysis of carbon-critical steel grades.
| Carbon Range | Below 30 ppm C (ULC/IF grade) |
| Sealing | Hermetically sealed mould for no carbon pick-up |
| Application | RH / VD degassed steels, IF/ULC grade production |
Celox-Type Sampler Probes
M-embossed celox-compatible combined temperature and oxygen samplers. Measures temperature, oxygen activity and collects a steel sample in a single immersion. Designed for maximum process data from minimum measurement interruption.
| Measurement | Temperature + Oxygen (combined) |
| Sample | Steel lollipop disc |

HydroinS Hydrogen System
HydroinS — In-Situ Hydrogen Measurement
In-situ dissolved hydrogen measurement in liquid steel, directly at the ladle or degasser. The HydroinS system provides real-time hydrogen readings for vacuum degassing process control — eliminating the risk of hydrogen-induced cracking in high-value steel grades without waiting for laboratory results.
Deployed at Gerdau's facilities for hydrogen control in high-strength engineering steel production.

2-in-1 & 3-in-1 Combined Probes
2-in-1 & 3-in-1 Combined Probes
Single lance immersion that simultaneously measures temperature + oxygen (2-in-1) or temperature + oxygen + steel sample (3-in-1). Dramatically reduces measurement time per heat, eliminates separate lance handling operations, and improves process efficiency.
