| Kit | Membrane and cap | Sensor type | Choose it for |
|---|---|---|---|
| 5908 | 1.25 mil PE, yellow cap — 6 caps per kit | Polarographic | The standard membrane — fastest response, the usual first choice |
| 5909 | 2.00 mil PE, blue cap — 6 caps per kit | Polarographic | Longer membrane life, at the cost of a slower response |
| 5906 | 1.00 mil Teflon, black cap — 6 caps per kit | Polarographic | Chemical resistance in aggressive water |
| 5913 | 1.25 mil PE, yellow cap — 6 caps per kit | Galvanic | The only kit for a galvanic sensor — not interchangeable with the polarographic kits |
