Physitemp multisensors are made with our specially manufactured thermocouple wire. We test and grade this wire to standards better than the accepted ''Special Limits of Error'' and guarantee 0.1°C accuracy in the range of 0-50°C . All multisensor probes conform to NIST standards. These multisensor probes are custom-made and should be ordered to your requirements on number of sensors and spacing between sensors.
Most common applications have been for cancer hyperthermia, where tissue temperature is an important clinical variable.
We use two different design techniques for the manufacture of the IT Series Flexible teflon probes. Each method has advantages:
METHOD A, two individual wires (one copper, one constantan) are used for each sensor. Sensors can be as close as 5 mm apart.
METHOD B, a single common constantan-wire is used. Separate copper wires are then connected to different points along the constantat wire to for the sensors. With this method, the probe can be made at least one gauge thinner and errors due to wiere conduction are reduced. Sensors must be no closer than 5 mm apart.
All IT Series Flexible Multisensor Probes are sheathed in Teflon and are implanted with regular hypodermic needles. UP to 10 sensors can be manufactured in a single probe for mapping of tumor temperature profiles. These probes are made to customer specifications and prices will be quoted at time of order.
Probes can be made to fit in needle gauge size:
