No more cumbersome cleaning. Lightweight, compact, and battery-operated for maximum portability. Single-handed operation from measurement to cleaning, without touching any liquid!

Increased efficiency over a conventional glass hydrometer and thermometer


A service tech visits 30 power systems a month. Using a standard hydrometer, it takes him 20 minutes per system to do the job. The DH-10 Digital Hydrometer reduces the service time to 2 minutes per system.
