Description
<p> The HMP230 series transmitters are microprocessor based instruments for the measurement of relative humidity and temperature; from these variables they can calculate dewpoint temperature, absolute humidity, mixing ratio, wet bulb temperature and enthalpy. The transmitters have two analogue outputs and they can be connected to a serial bus via the RS 232C interface or through an RS 485/422 serial module or a current loop module. At dewpoint temperatures below 0 C, the user can select whether the transmitter calculates dewpoint or frostpoint reading; as default, the transmitter calculates dewpoint.
