Figure 1 shows the different probe options available for HMT370EX series transmitters. The HMP371 fixed probe option uses a probe head that attaches directly to the probe body. In the other probe options (HMP373, HMP374, HMP375, HMP377, and HMP378), the probe head is attached to the probe body with a cable.
|HMP371 and HMP373 probes can also be ordered as temperature only probes that do not include humidity measurement options. For more information on the T-only HMP371 and HMP373 probe options, see Temperature only probe option (HMP371 and HMP373).
