9631-10D (for hydrofluoric acid or HF samples)
This refillable pH electrode with plastic body and integrated temperature sensor can measure 1% hydrofluoric acid solution (at 25°C, immersed for 1 minute) for about 1000x. Suitable for drainage water measurement after the etching process.
pH electrode, reference electrode and temperature sensor are combined in one plastic housing.
Temperature: 0 to 60 °C
