## What is MH Leakage Tester?

MH Leakage Tester assists with measuring building envelope and duct leakage in manufactured homes using a simplified protocol that relies on pressure changes and measured flow from one or more exhaust fans in the home. It is meant to be used with popular digital manometers with a Bluetooth connection.

The app provides estimates for building envelope leakage at 50 Pascals of pressure difference (CFM50 and ACH50) and duct leakage (CFM) under actual operating conditions. Confidence intervals and pass/fail status relative to user-defined thresholds are also provided.

Test data and results can be emailed in PDF, JSON and CSV formats.

### 5/5 — Quick Check for New Manufactured Homes

*2025-08-14*

This app gives a quick estimate of blower door and duct leakage test results, while also delivering actual exhaust fan air flow readings. It is a great way to start diagnosing home pressurization and air leakage issues.

### 5/5 — Simple Diagnostic Testing Protocol for New Manufactured Homes

*2025-03-03*

This app allows one to connect with a TEC DG-8 or DG-1000 manometer and Exhaust Fan Flow Meter to perform basic envelope and duct system air leakage testing on new manufactured homes. The app walks the user through the workflow for the tests and performs the calculations that return estimated leakage rates. The results track well with actual leakage tests as long as the home is pretty tight and outdoor conditions are not too windy. This can be a great way to do some basic home commissioning and setup QA screening.
