OMEGA offers three compact units for recording dc signals, and temperature (from thermocouples). The RD288 galvanometric recorder permits full-scale measurement of signals by striking a stylus against pressure-sensitive paper. The economical RD255 thermocouple recorder measures temperatures from remote thermocouple probes.
