Kofloc RK1400 High Pressure Rotameter

High-Pressure Flowmeter for Sensitive Measurements

This top-grade high precision, float type area flowmeter is a fruit of KOFLOC's challenge to boost the general perception currently conceived by people of a flowmeter of being a "mere yardstick" into a new conception that a flowmeter is a "precision instrument." This flowmeter particularly features its uniquely precision-formed glass tube and ultraprecision ball float that ensures accurate measurements of minute flows to medium flows.

Features

• Capable of measuring ultra-minute flows
• High precision measurement of flows
• Wide variations

Applications

• For integration into your equipment panel
• For flow inspections at laboratory
• For semiconductor manufacturing equipment
• For biotechnology industries
