| pH Sensor | Response Time | Temperature Range | Range | Price |
|---|---|---|---|---|
| pH Sensor | 90% of final reading in 1 second | 5 to 80°C | pH 0–14 | $79 |
| Tris-Compatible Flat pH Sensor | 98% of full response in 30 seconds at 25°C | 0 to 100ºC | pH 0–14 (Some sodium error in ranges greater than pH 12 due to thicker glass and higher impedance values) | $99 |
