Extech UV505 Pocket UV-Ab Light Meter

I love it. Very expensive though.

This is an easy-to-use UV meter. We use it for testing how much UV light is transmitted after installing various window films in our home and vehicles.

Präzise und zeigt die Werte in Echtzeit an. Interessantes Gerät

Avevo necessità di uno strumento affidabile per misurare i raggi uvb ed uva dentro ambienti per capire quanto fossero schermati dagli infissi, quanto dai vetri delle macchine 0etc per evitare e vessi a esposizione. Prodotto raro da trovare, devo raccomandarlo a chiunque abbia la stessa necessità poiché ( almeno finora) funziona perfettamente e mi ha fatto risparmiare molti soldi in pellicole che sarebbero state inutili. 🌟🌟🌟🌟🌟🌟🌟

I'll start off saying that sometimes I can be, er, unobservant. I tend to not read instructions at first. Just dive in. The battery door is held in place with a locking mechanism that requires a button press to release. I did not notice the button and could not slide the door off. I finally pried it open with a screwdriver. *Then* I noticed the button. Nothing was damaged except my pride, attesting to the ruggedness of the door latch. WHY it needs a lock, I have no idea. I have a couple of UV-A/B meters, including one where the sensor is separate and connected by a cable. Which design is better for you really depends on where you're using the meter, but is something to consider. If the light reading is in a more cramped or hard to reach area, you can extend just the sensor and have the display easily accessible. But you trade off size and durability (I've had the cables go bad after time.) If you perform a lot of UV-A/B measurements, eventually you'll probably wind up with both styles - compact all-in-one units like this Extech UV505, and one with a separate sensor. The all-in-one is my preferred style because I can stick it in a pocket, small tool bag pouch (I found that the cell phone pocket works well). The Extech UV505 includes a decent holster/pouch with top flap and belt loop. You can hang it from a tool bag shoulder strap, belt, etc. or just toss it in a toolbox/bag. The screen is easy to read and slightly below the face of the unit, so if you rest it face down on a surface you won't scratch it. There's a sensor cover that protects the sensor and blocks light to make zero-ing out the meter quick and easy. Overall build quality is good, but it is all plastic with no bumpers - a drop from a few feet onto concrete could be a problem. There's also a 1/4-20 tripod thread on the back. 2 AAA batteries are also included (they're in the bottom of the holster!) There's a loop for a lanyard, but no lanyard is included. I don't have a lab to test accuracy, but it reads the same as my other two meters.
