Closed-loop flow controller TPK 200iX

for airdigitalprecision

Overview
The TPK 200iX is a critical flow controller for inhaler testing, supporting Delivered Dose Uniformity (DDU) and Aerodynamic Particle Size Distribution (APSD) assessments. It is compatible with MDIs, DPIs, nebulisers, SMIs and nasal products and can operate standalone or connected to a centralised digital workflow for method control, user management and test record capture.

Key benefits

• Proven critical flow control for reliable inhaler testing.
• Guided setup via an intuitive step-by-step 7-inch touchscreen to promote consistent method execution.
• Expanded testing range with extended run time and low flow capability to cover a broader set of inhaler tests.
• Integrated connectivity to centralised management for methods, authorised users and test data.

Core capabilities and workflow features

• 7-inch touchscreen with guided, stepwise interface for setup and live run monitoring.
• Secure user management for authorised-user control and traceability.
• Equipment configurator to define and save controlled configurations per test method.
• Device resistance measurement to ensure correct critical flow control setup for the device under test.
• P1 rise-time logging to record pressure rise behaviour relevant to aerosol dispersion.
• Live run display showing test progress and key operating parameters.
• Auto-trigger options: MDI Actuation Sensor and footswitch; auto-triggers 7-series vacuum pumps.
• Automated in-situ leak testing and automatic test duration calculation to streamline verification.
• In-line flow measurement and automatic vacuum pump control for integrated operation.
• Available in standard and reversed pneumatic configurations (TPK 200iX and TPK 200iX-R).

Connectivity and integration

• Designed to connect with centralised data management to make approved methods and authorised users available at the instrument and to return operating information and reports to the central test record.
• Compatible with connected accessories that capture equipment identifiers and environmental data to strengthen traceability and documentation.

Applications

• DDU and APSD measurement of Dry Powder Inhalers (DPIs).
• Breath actuation control for MDI testing, including MDIs with spacers/VHCs and breath-actuated MDIs.
