Digital thermometer DT-504

Portable, single-channel thermometer DT-504 with replaceable probes is used to measure the temperature of different medium by direct contact of the probe with measurement object.

Digital Thermometers consist of electronic unit and replaceable probes.

As thermosensitive elements in probes thermocouples are used.


  • Changeable probe;
  • Measurement of temperature with resolution 1°С;
  • Low power consumption (at least 350 hours of operation from one set of batteries);
  • Large display with bright backlight;
  • 1 year manufacturer's warranty;
  • Powered by standard AA batteries.



DT-504 is used for highly precise measurement of temperature by direct contact with the measurement object.

Due to the possibility of changing the probe, measurements can be carried out for almost any media: liquid, dry, solid.

Connectable probes:

  • penetration (normal, enforced, for viscous and normal liquids);
  • surface (normal, bent, high-temperature).
