YSI 500 Series
Every Probe traceable to NIST and compatible with 4600 series Thermometer. Due to the small size of the thermistor temperature sensor prevents use of the patented process for probe interchangeability. Therefore a chart is supplied with each probe for the conversion of indicated temperature to actual temperature. The 500 series are ideal for Laboratory and Research applications where size and rapid response is required.
