Direct Answer: The DEK‑TRON Terg‑O‑tometer, also known as a Tergotometer, evaluates the washing and detergency performance of cleaning agents under controlled laboratory conditions following ASTM test methods.

What is the Terg‑O‑tometer?

The DEK‑TRON Terg‑O‑tometer is a precision instrument designed to simulate mechanical washing actions in order to evaluate detergent efficiency and soil‑removal capability. It measures how effectively surfactants and cleaning formulations perform across different temperatures, agitation speeds, and sample loads.

How does it work?

The system features an advanced PLC‑controlled interface with custom software to regulate the cycling speed and impeller motion of each test station. The standard configuration includes eight test stations, each with individual stainless‑steel beakers and shafts. During operation, samples are agitated under consistent conditions while temperature is maintained via a built‑in stirring and heating system, ensuring accurate comparison of cleaning performance.

Key features

• Eight test stations in standard configuration
• PLC with precision speed and rotation control for each station
• All‑stainless‑steel construction (enclosure, reservoir tank, shafts, and beakers)
• Built‑in stirrer for uniform temperature distribution
• Insulated walls to minimize heat loss
• Emergency stop and water‑level warning system for safety
• PID temperature controller with adjustable setpoints
• Configurable test duration and active station selection (1–8)
• Optional integrated cooling system for sub‑ambient testing
• Voltage options: 110 VAC or 220 VAC

Applications

Used in detergent research, textile cleaning evaluation, and laboratory testing of surfactant formulations to study soil removal, rinsability, and overall washing performance under standardized mechanical agitation.
