Proceq Torrent

Concrete Air Permeability Tester

The Proceq Torrent is a portable, non‑destructive instrument designed to rapidly assess the air permeability of concrete cover. Utilizing a unique two‑chamber vacuum cell setup and pressure regulation system, it measures the permeability coefficient (kT) to evaluate concrete durability and resistance, all within 2 to 12 minutes of on-site testing.

Features

Two‑chamber vacuum cell principle for perpendicular airflow penetration
Integrated pressure regulator and automatic kT computation
Intuitive menu system with graphic LCD display (128 × 128)
On-device calculation of permeability class via kT and optional resistivity correction
Transfers data via RS‑232 or optional USB adapter
Stores up to 200 measured values onboard
Lightweight handheld unit; vacuum pump ordered separately
Battery powered with six AA (LR6) cells (~60 h runtime)

Applications

Concrete durability and permeability assessment
Evaluation of concrete cover quality
Assessment of fire‑damaged structures
Effectiveness testing of protective coatings
Non‑destructive site testing for construction QA/QC
