QUESTION: Can the Vaisala HMP155 fit inside the MeteoShield Pro?
While the MeteoShield Pro is the highest precision solar radiation shield for meteorology in the marketplace, the Vaisala HMP-155 temperature and humidity probe is arguably the most accurate sensor for stable long term measurement in the industry.
Since the precise Vaisala temperature and humidity sensor can only accurately measure air conditions that exist inside a radiation shield, the solar radiation shield dictates the total accuracy of the sensor shield combination.
During sunshine hours, minimizing errors from solar heating and reflected and radiated light and heat from the ground is essential.
During rain, protection from direct impact of dispersed rain droplets and water spray due to wind is essential to minimize evaporative cooling errors and latent heat effects of wet sensors.
The MeteoShield can be created in a taller version if required by the customer for a small extra fee.
