THERMISTORS: TYPE
Biomedical Chip Thermistor assemblies designed applications involving both intermittent continuous patient temperature monitoring. Repeatability fast response essential only intermittent temperature requirements associated with oral rectal fever measurements, also with continuous monitoring often necessary during induced-hypothermia general anesthesia, when employed care infants premature babies. Intensive care units along with recovery rooms have also adopted patient temperature part their vital sign monitoring procedures. Temperature monitoring skin surface, tympanic, esophageal, foley catheters biofeedback applications also improved high stability tight interchangeable tolerances designed into each Thermometrics' Biomedical assembly.
APPLICATIONS:
complete line standard sub-assemblies available, shown Figure however, continuous research development efforts within Thermometrics have resulted only these field proven designs, development Unitherm Thermochip Thermistor designed exclusively biomedical applications range Although cost, these highly stable, precision thermochips provide reliability, tight interchangeable tolerances, geometries, fast response times required. keep pace with this ever-improving biomedical market, material system processing parameters closely monitored improved continually provide with reliable, quality products. addition, should require Thermometrics employs complete staff experienced full-time applications engineers welcome your inquiries, whether it's assistance, help with your design requirements concerning existing applications.
