The requirements of a data acquisition system to monitor the performance of electric air‐air heat pumps in the field are discussed and the design and application of a system meeting these needs is presented. Audio cassette tape is used to record typically 21 data channels using 8 bit representation. With a channel sampling interval of 101 s, one track of a C90 cassette records data for more than 7 days. In applications where a number of loggers may be needed, the low marginal cost of the system makes this approach to data collection attractive.
