The PRM-9000 Geiger Counter can pick up several types of radiation: alpha, beta, gamma, and X-rays. This makes it pretty handy for different uses, like keeping an eye on the environment or checking safety in places where radiation might be a concern.
It runs on a 9-volt battery. If you switch to a lithium one, the manufacturer claims it can last over four years with normal use, while a standard alkaline battery can go for about two years.
But our research found that getting to the battery can be a bit of a hassle for some folks. There's some fiddling with screws involved, which could be a bit tricky if you're not careful. The manual doesn't offer much in the way of pictures, which might be a bit of a downside if you're not super experienced.
Some find that using rechargeable 9-volt batteries works well with the PRM-9000. You can save power by tweaking settings, like limiting backlight use and lowering alarm thresholds, to make the battery last even longer.
One user mentioned in our data had good results with a USB-C rechargeable 5400 mAh battery, barely needing to recharge with adjusted settings.
So, while the PRM-9000 doesn't skimp when it comes to battery life, you should plan on changing batteries now and then. It might be worth learning how to handle the battery compartment and having an extra on hand if you use features like data logging or backlighting a lot.
If you're using it frequently, rechargeable batteries could be a good bet—they'll help cut down on costs and are a greener option.
For more details, you might want to look at the manufacturer's description or chat with others who use the PRM-9000 to get some practical tips on making the most of it.
