Agilent / HP 2804A

This Quartz Thermometer allows you to easily measure temperature with exceptionally high accuracy and resolution.

Absolute accuracy is ±40 millidegrees Celsius over the range of -50°C to 150°C, NIST traceable to ITS-90.

The usable resolution of 0 .0001 °C allows you to measure temperature changes that could not be detected by other digital thermometers.

This unit can be used with one or two temperature sensing probes, the temperature of either probe, or their difference, can be measured and displayed under pushbutton control.

Display resolution is selectable from 0.01 to 0.0001°C (0.1 to 0.001°F) by pushbuttons.

An internal switch allows you to easily select measurement in the Celsius or Fahrenheit temperature scale.

Temperature is measured and displayed automatically with the microprocessor and electronics provided in this package.
