Here's some info I came across that may help. Surfing for stuff like this is fun.
In 1874, the station instrumentation at Chicago (a major station) included "Two standard barometers, three standard thermometers, one standard minimum thermometer, one standard maximum thermometer, one standard water-thermometer, one standard hygrometer, one standard anemometer, one self-register for anemometer, one standard wind-vane, one standard rain-gauge." At Dodge City, Kansas (a lesser station) the instrumentation included "One standard barometer, one standard thermometer, one standard minimum thermometer, one standard maximum thermometer, one standard hygrometer, one standard anemometer, one small wind-vane, one standard rain gauge."

And they were doing 3 times a day measurements.
