The HMP110 humidity and temperature probe used in HMT140 is fully interchangeable. You can easily remove the probe and replace it with a new one without having to adjust HMT140. You have the following options when purchasing a new probe from Vaisala:
- Order a new probe and keep your current one.
- Order a new probe and return the old one to Vaisala (replacement probe).
| Only probes that have a compatible digital output (VDIGI mode) can be used with HMT140. Compatible probes have the letter "V" as the first letter in their order code. The order code is written on the probe. |
