OrienTek T20 Portable Testpro Optical Power Meter
1. 850/1300/1310/1490/1550/1625nm
2. With FC/SC/ST Connector
3. Six wavelength
4. Rechargeable Li-battery instead of dry battery

T20 Portable optical power meter is an accurate and durable handheld meter designed for the installation, operation and maintenance of optical fibre network. It is a compact device with backlight switch and auto power on-off ability. Besides, it provides ultra-wide measurement range, high accuracy, user self-calibration function and universal port. In addition, it displays linear indicators (mW) and non-linear indicators (dBm) in one screen at the same time.

Features:

1. Self calibration by user himself

2. Rechargeable lithium battery supports continuous work for up to 48 hours.

3. Linear indicators (mW) and non-linear indicators (dBm) display in one screen

4. Unique FC/SC/ST universal port (see Figures 1, 2), no complex conversion

5. Optional auto power-off ability

6. Backlight ON/OFF
