Product Overview

The NT393 optical multimeter uses a high-sensitivity detector with single-chip microprocessor control. The body shape is novel and meets ergonomic requirements — attractive and durable. The optical power meter and visible fault locator use embedded detector and laser, so both are well protected. Optical power meter / laser source, RJ45 sequence and flashlight are standard; visible fault locator, RJ45 tracking and Bluetooth are optional. It is mainly used for continuous optical signal power measurement, fibre link loss test and fibre line on-off test, and is widely used in cable construction and maintenance, fibre communication, fibre sensing and optical CATV.

LS wavelength options: 850/1300 nm, 1310/1550 nm, 1310/1490/1550 nm, 1310/1550/850/1300 nm and 1310/1550/1490/850/1300 nm.
