The OMEGA™ HH42A digital thermometer is the newest member of our series of instruments based on our high-precision temperature measurement system technology. This device provides the accuracy and resolution needed to meet the measurement demands of precise laboratory work or critical process control and testing. It comes with free software, so users can start recording, graphing, and storing data on a PC in familiar file formats within minutes of opening the box. A well-defined command set and output data format allow users to connect the computer system to the thermometer to create custom displays and report formats. There are a variety of specially designed RTD probes available for use with this instrument. Selected probes are hardwired to the instrument and calibrated together to meet specific high-precision requirements. Interchangeable probes with plug-in connectors are also available.
