Humidity and Temperature Probes QMH101/102

The Vaisala Relative Humidity and Temperature Probe QMH101/QMH102 is based on Vaisala's field-proven HMP45D probes. The HMP45A and HMP45D probes will be available until the 30th of June, 2010. The HMP155 will replace the current meteorological probes HMP45A and HMP45D.

The HMP155 can be ordered with such a configuration that it will replace the HMP45A and the HMP45D without additional adapters. Thus, the same output/supply cable length and the same outputs are available as in the HMP45A/D probes. The HMP155 can also be ordered with the same HUMICAP®180 sensor that is in the HMP45A/D.
