The Medical Catheter micro-BetaCHIP probe is packaged similar to the standard micro-BetaCHIP Probe except that the thermistor element is a glass coated thermistor of specific resistance value. The glass coated thermistor adds extra moisture protection to the probe design.
The probe is produced for Medical applications which require rapid temperature response and very small size. When used in thermodilution catheters, the thermistor measures blood flow characteristics in the human body. Supplied with custom lead lengths near 1.5 meters on small reels (spools) with calibration data at 37oC. The standard thermistor is denoted as G22K7MCD8. Many other custom versions have been produced...
