Mastech MS8229 Auto-Range 5-in-1 Digital Multimeter

Sometimes it’s nice to have a tool that simply does it all… The newly released Mastech MS8229 Digital Multimeter (DMM) is an improved and modified version of the Mastech MS8209 and does it all. It combines a multimeter, a sound level meter, thermometer, luxmeter, and humidity meter all in a single box. The unit has some very handy features. It provides temperature & humidity display and has an audible + LED warning for correct connection of the probes. The back-lit LCD Screen makes for a very easy to read screen, in dark or light rooms.

The multimeter is quite easy to use – even with gloves. The centrally-located rotary knob easy moves around between the various modes. The probes are inserted below and the sockets are clearly labeled for measuring current, voltage, temperature, and resistance. One thing we really appreciated was the unit’s ability to automatically adjust the measurement range as needed. This saves a step and means less hassle for using the unit, especially with gloved hands.
