A McGill Leak Detective test kit makes it easy for you to measure duct system leakage. We offer four standard sizes, each available either as a kit or mounted on a wheeled cart. Other sizes are available as nonstandard items. Leak Detective carts, orifice tubes, and test kit components can be ordered individually. A standard leakage test kit consists of the following equipment:

1. Calibrated orifice tube
2. Certified calibration chart
3. OSHA-approved fan with an inlet damper control
4. Two U-tube manometers
5. Vinyl tubing
6. Dye
7. 10-foot flex duct, adapter and clamps

The standard test kit contains a 4-, 5-, 6-, or 8-inch orifice tube calibrated for positive pressure system testing. The fans, which come with an inlet damper control, can be ordered for 110- or 220-volts and 50- or 60-cycle current.
