Chub-E4 1529 Standards Thermometers

The Chub-E4 has four inputs for reading four different sensors simultaneously. The inputs can be configured in one of three ways according to your needs: four thermocouple input channels, four PRT/thermistor input channels, or two of each. This thermometer makes it easy to obtain accurate readings from thermocouples, PRTs and thermistors with a single instrument.
100-ohm, 25-ohm and 10-ohm PRTs and RTDs are read using ITS-90, IEC 751 (DIN) or Callendar-Van Dusen (CVD) conversion methods. Typical accuracies include ±0.004°C at −100°C and ±0.009°C at 100°C. Thermistor readings are converted using the Steinhart-Hart polynomial or the standard YSI-400 curve and provide ±0.0025°C accuracy at 25°C with 0.0001° resolution.
