Highly recommend for a technician. - I picked this up when my other opm quit working on me. I didn't want to spend a ton of money on one, and honestly, its been pretty decent for the price. It is super compact and weighs almost nothing so it's easy to shove in my pocket and go. It has been accurate so far. I don't use it for every wavelength, obviously but 1550 has been spot on. I've had it for a few months now and have only charged it twice. The battery life is great. It does feel a little cheaply made, but for the price, that is to be expected. If you need a reliable backup meter or one to carry around with you and not have to worry about losing or breaking it, this is it. Highly recommend. I do intend on buying a better one at some point and using this for a backup, but you can't go wrong. Review: Small, simple and gets the job done. - Their is nothing that I don't like. Very easy to use, seems accurate enough for field work and can easily slip in a pocket or use the case that comes with it. ## Features - Linear optical power and logarithmic power display, Relative value measurement - Automatic measuring range adjustment and remaining power indication - Low power consumption, continuous work more than 80 hours - Universal 2.5mm interface, supports FC, SC and ST connectors - Compact and portable design, 68g in weight, ensuring better hand-held feeling / easy carry ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07X7HWBPG | | Best Sellers Rank | #174,613 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #370 in Network & Cable Testers | | Brand | QIIRUN | | Brand Name | QIIRUN | | Color | Blue | | Compatible Devices | Devices with FC, SC, or ST connectors and fiber optic cables | | Customer Reviews | 4.5 out of 5 stars 427 Reviews | | Included Components | Optical Power Meter, User Manual, Carry Case | | Item Dimensions | 4.72 x 1.3 x 1.18 inches | | Item Weight | 68 g | | Item dimensions L x W x H | 4.72 x 1.3 x 1.18 inches | | Manufacturer | TL Tool | | Measurement Type | Optical Power | | Model | -70~+10dBm OPM | | Number of Items | 1 | | Number of Packs | 1 | | Part Number | SNS-192-B07X7HWBPG | | Power Source | Battery Powered | | Specification Met | Qiirun | | UPC | 631384994496 | ## Product Details - **Brand:** QIIRUN - **Power Source:** Battery Powered - **Color:** Blue - **Item Weight:** 68 Grams - **Item dimensions L x W x H:** 4.72 x 1.3 x 1.18 inches ## Images ![TL537 Optical Power Meter — Fiber Light Meter -70~+10 dBm with 6 Calibrated Wavelengths, FC/SC/ST Universal Interface, 68g Lightweight Fiber Optic Tester for FTTH Splicing & Maintenance - Image 1](https://m.media-amazon.com/images/I/41vcFurBbML.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works well, cheap, and easy to use.
