RI-S320 Automatic Horizontal Coulometric Sulfur Analyzer — RoyIntelli

Overview

The RI-S320 measures total sulfur in coal, coke, oil and solid biomass by coulometric titration — the classical reference method used in trade settlement. Load up to 20 samples (or run single samples), and the analyzer handles delivery, electrolysis, endpoint detection and reporting automatically.

A horizontal imported-material furnace with national-standard ceramic boats guarantees complete combustion, while the large-electrode electrolysis cell delivers repeatable results even at low sulfur levels. DSP control with hardware integration keeps real-time response and allows easy software upgrades.

Key Features

Multi-damping sample pusher

Shock-absorbing delivery mechanism feeds boats smoothly — no dropped or jammed boats, even during long overnight batches.

Large-electrode electrolysis cell

Bigger platinum electrodes improve charge efficiency and repeatability, especially on low-sulfur coal between 0.01 % and 1 %.

Self-diagnostics at boot

The instrument checks itself at power-on, displays fault codes and maintenance suggestions to keep downtime short.

Easy electrolyte service

Drain valve for quick cell rinsing plus an oversized drying tube cut consumable changes to minutes per week.
