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).
NOTE Only probes that have a compatible digital output (VDIGI mode) can be
used with HMT120 transmitter. Compatible probes have the letter "V" as
the first letter in their order code. The order code is written on the probe.
