What kind of battery does it have?

1 x 3V button battery CR2032 , it's included in the water tester. Sincerely hope you enjoy the products we sell on Amazon!

how can i test if the unit is accurate could i use distilled which i assume should be zero, thanks tom

Thanks for your question. This TDS meter is pre-calibrated in factory, no need calibrate again by customer, we do this to prevent as many calibration related mistakes as possible, and it's easier to use. To maintain the accuracy, it's better to rinse the probe with distilled water after each use. For your mentioned distilled water, it should read 0 ppm theoretically, but in actual application, if you can't keep test condition very clean, it may read 0-2ppm usually.

Can this also check for ph ?

It Does not. It measure TDS , EC and Temperature 3 in 1. PH Meter is another tester.

Has anyone else experienced this reading into the hundreds on very low ppm water after a couple weeks of use? solutions?

Are you rinsing the probe with distilled water after each use and patting it dry, if not, dried solids will build up on the probe and render the measurements inaccurate.

I’m extremely happy with the HoneForest TDS Meter! I used it on my tap water (98), distilled water (0), and filtered water (88), and the readings came out pretty good! It was really interesting to see the clear difference between the three. The device is very easy to use right out of the box. Just turn it on, place it in the water, and within seconds you get a clear reading for TDS, EC, and temperature. It feels well-made for the price, compact, light weight, and reliable. If you want a simple and accurate way to test your water quality at home, this is definitely worth it. I highly recommend it!
