If
you're an environmental health inspector or you want to monitor
sound, light and other factors in your work place you need this 5-in-1
digital environmental multimeter which comes with test leads and K
type thermocouple
Measures the Following :
- Sound
- Light
- Humidity
- Temperature
- AC/DC voltage
- AC/DC current
- Resistance
- Frequency
- Duty
- Capacitance
- Continuity diode test
The large
LCD display is easy to read and is backlit, allowing for reading in dark
rooms or workshops. The central dial has various positions allowing you
to choose which is appropriate for the measurement you want to take,
making this an essential piece of equipment for general maintenance and
measurement.
