Hello everyone hope you’re doing well. So my PPM pen stopped working. Does anybody have any suggestions on a cheap reliable pin? Thank you for your feedback
This one is still going strong after 2+ years

Bobby Digital what’s up brother. That’s actually the one that I have. I kept having to calibrated it it would fluctuate 100 PPM. But all of a sudden it just stopped working. Maybe I just got a dud. Maybe I’ll get it again. Thanks for your feedback

That’s odd. Mine doesn’t allow for calibration.

I apologize I don’t mean calibrate it. I meant as far as putting it in the test solution to see how far it’s off. I’ve tested about five times since I’ve got it and the last six months and every time it’s been a little different.
They do have batteries that can’t be replaced. Maybe the battery was dying causing the bad readings.

I just used it two days ago. Who knows maybe I left it on. And somebody else just mentioned that is a different PPM pen. Maybe I’ll go with the one you got. Like I said mine fluctuated anyways. Straight out of box it was plus 44
LOL. I just posted maybe I left it on. But I’m pretty sure that turns off doesn’t it.
look at Bobby’s last post, sorry for buttin in.

Well, looks like yours is the newer version (2.0). This is mine. Can’t seem to find the exact one on Amazon anymore

I will stop by the store tomorrow and get a new battery maybe that’s the problem. If not I’m going to look for you the old version 
and I guess I need to slow down on the replies as somebody else has mentioned I missed a message. Sorry

Most of them are all the exact same meter. Just company’s put their own logo on it. Much like the cheap Amazon lights, fans, etc. Same exact hardware, just branded with a different name.

You might be able to change the battery. Just have to take it apart. Hopefully the battery isn’t soldered in. Unless you have solder ready to go then you’re all set.

If you have a multimeter you can test the voltage on that battery. If it’s under 3v then that’s likely the issue.

Duh. Lol. I’m normally a pretty fart smeller I mean smart Feller. At least average. LOL. I’m just sitting here watching Swamp People taking bong hits my son’s at his mom’s house and not even thinking about testing that battery. Thank you so much for reminding me I can do that. And I did. And it is dead. LOL. I must have left it on 2 days ago. Stoners what do we do with ourselves. Oh I know smoke another Bowl. So I will be off to the dollar store tomorrow to get some batteries. Thanks again for your time I greatly appreciate it.
