Review on Apera Instruments AI1213 Replacement Tester by Jason Vigil
The sensors don't last 4 months and work perfectly
I bought the pen that came with the sensor and 2 other sensors for just over a year. I keep my PH meters in a liquid container and calibrate them properly, but these sensors seem to be built to last no more than 4 months. I'm disappointed, it seems like a cheaper option to buy a cheap Chinese meter every 3 months, you'll throw them away too, but at half the price.
- Quality construction
- Requires a socket
