Introduction

The 1504 Thermometer Readout is a low-cost high-accuracy digital thermome-

ter readout designed to be used with thermistors or RTDs with a nominal resis-

tance 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. Features of the 1504 include:

• Measures with most any thermistor

• Four-wire connection eliminates lead resistance effects

• Accuracy: 0.003°C, typical

• Resolution: 0.0001°C

• Fast one-second measurement cycle

• Adjustable digital filter

• Accepts Steinhart-Hart characterization coefficients

• Also accepts Callendar-Van Dusen coefficients

• Auto-ranging from 0Ω to 1 MΩ

• Excitation current adjusts automatically to minimize self-heating

• Displays temperature in Celsius, Fahrenheit, or Kelvin or displays resis-

tance 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
