## Description

desertcart.com: VIVOSUN TDS Tester 3-in-1 TDS EC & Temperature Meter Ultrahigh Accuracy Digital Water Quality TDS Tester (Blue) : Industrial & Scientific

Review: Great but cheap - Its is as described and works as described and cost almost nothing. I cant complain about a thing. 5 of 5 I payed $9.99
Review: POS - The most inaccurate low budget ppm meter I’ve ever used, and believe me I’ve used a lot of these cheap things. This one will be reading 1811 ppm. Take it out of the water, tap it on the wall bc I know what it’s reading is not accurate. Put the ppm meter back in the water after a solid wall tap, reads 1934. Thanks, 80 ppm monopotassium phosphate over my target number because this thing is a POS. Don’t buy it. I, as a broke ass individual, is telling you it’s worth it to own the bluelabs meter. Not the stick one, but the one with the probes on cords attached to the display. I hope this helps someone not only save $8 or $11 or whatever this pos costs.
