🔁 The ACD minibump is now the minigen

For 25 years, the minibump has been trusted for quick, reliable PPM bump testing from a pocket-sized handheld unit. Now it has evolved.

The minigen keeps the proven bump test function, with automatic shut-off after 180 seconds, supporting Cl₂, H₂S, H₂ and HCN from a single unit.

What’s new is flexibility.

By simply swapping the cell, the minigen converts into a continuous flow gas generator, delivering:
• Up to 10 hours of continuous output
• Equivalent to up to 58 litres of gas from a single cell

Simple to use, highly portable, and offering the lowest cost option on the market for both bump testing and continuous gas supply.

The image shows the minigen supplied in its hard case with spare cells.
