Leaktronic 4 is a microprocessor-controlled leak detector with a Hydrogen specific sensor. Nitro Trace leak detection gas, which is a blend of 95% nitrogen and 5% hydrogen. Hydrogen is used because it has the smallest molecule of all gasses and will find the smallest leak. Nitrogen is 80% of ambient air, so it cannot be detected electronically hence the addition of detectable hydrogen. Leaktronic 4 is essential when regularly leak testing with Nitro Trace or other 95/5 forming gases
