MASTECH MS8229 Environmental Monitoring Instrument Multimeter to Measure the Temperature and Humidity Illumination Noise

Description
The instrument is portable, professional measuring instrument, with a large screen LCD digital display (three sets of data display), and back light source, the user easy to read. Single hand operation to facilitate the measurement range switch, with overload protection and low battery indicator. Whether professional, factory, school, lovers or family use, is an ideal multifunctional instrument.
The instrument has the anti table pen plug acousto-optic warning device. This provides more protection for the instrument, so as to avoid misoperation damages instrument.
The 5 1 digital multi tester combined with sound level meter, light intensity meter, thermometer and hygrometer, digital multimeter functions.
Sound level measurement function can be used for noise measurement factory, school, office, airport, family, sound design studio, auditorium, high fidelity checking device.
Optical measurement function is used to measure the site illumination, it is affected by angle of incidence light effect.
Humidity, temperature measurement function is used to measure the humidity, temperature and the temperature of the object.
Digital multimeter for DC voltage, AC voltage, DC current, AC current, resistance, capacitance, frequency, duty ratio measurement and the on-off circuit, diode test.
When in use, the instrument display value and unit symbols of measured.
