Description
The Digital DC Voltmeters, also known as LCD classroom DC voltage meters, are designed for measuring direct voltage in physics laboratories, electronics classrooms, university teaching laboratories and supervised educational circuit experiments.
These Australian-made DC voltmeters are designed for classroom durability and simple operation. The clear LCD display supports teacher demonstrations and student practical work where DC voltage readings need to be observed quickly and accurately. The range includes three DC voltage options. The 2 V model measures from 0.000 to 1.999 V DC with 1 mV resolution, the 20 V model measures from 0.00 to 19.99 V DC with 10 mV resolution, and the 200 V model measures from 0.0 to 199.9 V DC with 100 mV resolution.
The input impedance is stated as 10 MΩ for the voltmeter range. This supports classroom voltage measurement while reducing loading effect in suitable educational circuit applications. Each meter is powered by a standard 9 V battery, which is described as easy to change when required. A low battery alarm displays before replacement is required, with the supplied details stating that accuracy is not affected during the warning period.
Automatic power off occurs after 20 minutes to help protect against battery drain when the meter is left on. One touch of the ON button restores the display, supporting practical use across repeated classroom activities. If the rated DC range is exceeded, a red LED illuminates as an over-range reminder. The supplied details state that this indication is designed to prevent classroom damage risk during suitable use. The design has no knobs, switches or fuses to replace, reducing routine maintenance compared with more fragile analogue meter styles. This makes the range suitable for repeated student handling in supervised educational environments.
LabChoice Australia supplies Digital DC Voltmeters for school physics departments, electronics classrooms, university teaching laboratories and educational electrical workspaces. They are suitable for supervised DC voltage measurement, circuit analysis, Ohm’s Law practicals, component testing and hands-on student investigations using compatible apparatus.
