Hey
Browsing local adds I found this old pH meter. I tried to find any instruction or manual, but no luck. I get curious, how you should operate such device. And if that may be a good idea for reliable pH measurement today for a small grower, or should I stay with cheap pH meters with regular calibration and usage of storing solution?
I see here 2 metal probes. Like from electric multimeter, not a bulb with a liquid as the sensor.
