## Description

## Tips for day-to-day use

For checking voltage, current, continuity or temperature around a home workshop, the PROSTER T28B combines several diagnostic functions in one digital multimeter. Its 6000-count display and auto-ranging operation help make readings easier to follow, while the backlit LCD and built-in flashlight support work in dim spaces. Non-contact voltage detection adds a way to check for voltage without touching a conductor with a probe.

Choose this all-in-one approach when you want electrical measurements and temperature checks from the same tool. For jobs that only call for a single type of reading, a dedicated tester may be a simpler fit, the T28B is geared towards switching between different checks.

## Pros

The meter measures AC and DC voltage and current, resistance, capacitance, frequency, duty ratio and temperature. It can also test continuity, diodes and transistors, making it useful for a range of troubleshooting tasks in schools, labs, factories and home maintenance. The 20A AC/DC current range and TRMS design bring together key functions for varied electrical checks.

For a practical example, when diagnosing a circuit in a poorly lit work area, the backlight makes the display easier to read and the flashlight helps illuminate the work. A magnetic back and rear bracket offer convenient probe placement, while the data-hold function lets you retain a displayed reading as you note it. The protective silicone cover, overload protection, short-circuit protection, low-battery indication and automatic power-off add useful details for regular handling.

The sampling speed is 3 times per second, and the meter supports both auto and manual range selection. A temperature probe is included for readings from –20 to 1000°C. The supplied leads and alligator clips provide different ways to make test connections, and the cloth bag keeps the kit together for storage or transport.

## Questions before you buy

**What can the PROSTER T28B measure?** It handles AC and DC voltage and current, resistance, capacitance, frequency, duty ratio and temperature. It also provides continuity, diode, transistor and non-contact voltage tests.

**Can it help with measurements in a dim workspace?** Yes. The backlit LCD helps make readings visible, and the built-in flashlight illuminates the work area. Its magnetic back and rear bracket also support hands-free probe placement.

**What comes with the multimeter?** The kit includes the meter with protective holster, test leads, a temperature probe, alligator clips, a screwdriver, spare fuses, 4 AAA batteries and a cloth bag.

## Buying verdict

The PROSTER T28B suits users who want one meter for varied electrical checks and temperature readings, rather than a tool limited to a single measurement. Its 6000-count display, 20A AC/DC current capability, NCV testing and work-friendly lighting make it a practical fit for home maintenance, workshop troubleshooting and technical settings.
