Lovibond® ET830 Laboratory Floc Tester, Portable, 4‑Position

Lovibond® ET830 Laboratory Floc Tester, Portable, 4‑Position

The Lovibond® ET830 is a portable, laboratory floc tester designed for precise and reproducible coagulation and flocculation studies. Built for water and wastewater treatment applications, the ET830 enables operators to simulate real treatment conditions, determine the correct coagulant type, and optimize dosage before full‑scale implementation. Its compact design, illuminated display, and flexible speed control make it ideal for field use, pilot testing, and laboratory process optimization.

Key Features

• ASTM D2035‑19 compliant: Performs standard jar‑test flocculation procedures for reliable, comparable results.
• Portable design: Lightweight housing with sturdy transport handles and a 12 V DC car adapter for mobile operation.
• Two‑step testing mode: Time‑controlled or manual switching between two preset stirring speeds for reproducible floc formation.
• High vessel compatibility: Accepts beakers from 500 mL to 1500 mL (full compatibility at all four stirring positions).
• Precise speed control: Digital adjustment from 20 to 250 rpm with ±1 rpm precision and 5 rpm resolution.
• Durable construction: Corrosion‑resistant stainless‑steel stirring rods and paddles.
• Large illuminated display: Clear visibility of speed and timer settings in laboratory or field environments.
• Universal operation: Intuitive, language‑independent membrane keypad.
