The Fluke 1504 Thermometer Readout is a low-cost high-accuracy digital thermometer readout designed to be used with thermistors or RTDs with a nominal resistance of 1,000Ω or greater. Its unique combination of features makes it suitable for a wide variety of applications from laboratory measurement to industrial processes.
If you need more accuracy in a limited temperature range, the Model 1504 Tweener gives it to you as a thermistor readout. Thermistors are less fragile than PRTs and less likely to be impacted by mechanical shock. Thermistors are more sensitive to temperature, have faster response times, and come in many shapes for different applications.
Measures with most any thermistor.
Four-wire connection eliminates lead resistance effects.
Accuracy: 0.003°C, typical.
Fast one-second measurement cycle.
Adjustable digital filter.
Accepts Steinhart-Hart characterisation coefficients.
Also accepts Callendar-Van Dusen coefficients.
Auto-ranging from 0Ω to 1 MΩ.
Excitation current adjusts automatically to minimise self-heating.
Displays temperature in Celsius, Fahrenheit, or Kelvin or displays resistance in ohms.
Password protection of critical parameters.
Large, bright eight-digit LED display.
Serial RS-232 interface standard; IEEE-488 GPIB interface optional.
Detachable power cord.
Optional 12 V DC power.
Light weight, small and portable.
Sturdy, reliable construction.
