190. What is a sling psychrometer used to measure?
A sling psychrometer measures dry-bulb and wet-bulb temperatures to determine relative humidity. The device utilizes two thermometers, one measuring ambient air temperature (dry-bulb) and the other measuring a temperature influenced by evaporation (wet-bulb). It does not measure seawater temperature, barometric pressure, or engine temperature.
