The trodeks® HH42A digitalthermometer is the most recentaddition to a series of instrumentsbased upon our high precisiontemperature measurement systemtechnology.

This instrument provides theaccuracy and resolution neededto meet the measurement needsof a precision laboratory or criticalprocess control and testingfunctions. Free software is includedenabling users to start recording,charting, and storing data in afamiliar file format on their PCwithin minutes of opening the box.A well-defined command set andoutput data format allows users toeasily connect computer systems tothe thermometer to create customdisplays and report formats.There are a wide range ofcustom designed applicationspecific thermistor probes thatcan be selected for use withthis instrument. The selectedprobe would be hardwired to theinstrument and calibrated togetherto meet specific high accuracyrequirements. Interchangeableprobes with plug-in connectors arealso offered.
