Digital Insutest
1000 / 2500 Digital
Insulation Testers with auto range selection is a real digital
Insulation resistance tester+ digital Multimeter. It has features of
complete functions, high accuracy, reliability in operation and
convenience in use Output test voltage can be switched among
250V/500V/1000V for Metrix, 1000
& 500V / 1000V / 2500V for Metrix, 2500 Metrix -1000 / 2500 can
monitor the output high voltage in real-time way. At any time, the user
can observe actual measurement voltage that is output by the meter,
effectively avoiding misjudgment caused due to output voltage and
conforming to the rated value. The measurement range of the meter can
reach up to 40G ohm. The measurement time can be set up according to
requirements. After a measurement is completed, the measured result can
be kept automatically. Functions of the digital multimeter include AC /
DC voltage, current, resistance, capacitance, frequency, diode, and ON
/ OFF measurement. The functions of the multimeter, you need not be
worried that you would suffer electric shock due to high voltage
generated by the insulating resistance tester. The product is
applicable to measurement of the insulating resistance f various
insulating materials and electric equipment's such as transformers,
motors, cables, switches and electric apparatuses. It is also
applicable to maintenance, test and inspection of various electric
equipment's. it is compact in structure, convenient to carry and an
ideal electrical and electronic testing meter of yours
