The mounting cap on the DHL-1 Drum Alarm makes it easy to switch to a new drum when the old one is full since you don't have to disconnect tubing while you unscrew a cap - it just drops over the bung. The cap keeps debris out of the drum, and suppresses vapors even liquid ammonium hydroxide is not a problem.
Attached feed tube on the DHL-1 Drum Alarm makes sure the alarm stays with the alarm. Your tubing is secured with a foolprooof all-polypropylene compression fitting to eliminate chance of spillage due to hose disconnection.
Float is protected inside a rigid pipe so it can get knocked around without worry. Screen protects float from debris on model DHL-1.
Uninterruptible battery power works through power failures, can't come unplugged, or be defeated. And, because the Drum Alarms don't use any power until alarming, the batteries last for years.
