TES- 1300/1303 Thermometer

The TES-1300/1303 are K-type thermocouple thermometers designed for single or dual-channel temperature measurement. They provide accurate readings across a wide range, support differential and dual-point display (TES-1303), and offer data output for recording.

  • Measuring Range: -50°C to 1300°C (-50°F to 1999°F) with dual-channel input on TES-1303.
  • Accuracy & Resolution: 0.3–0.75% of reading + offset, with 0.1°C/°F resolution for low ranges and 1°C/°F for higher ranges.
  • Data & Output Features: Maximum/Hold function, auxiliary output for data recording, T1/T2 dual-point display and differential measurement (TES-1303).
  • User-Friendly Design: Switchable °C/°F, compact size, battery-powered (9V), and flip-up stand for easy use.

Description

The TES-1300/1303 Thermometer is a compact, high-precision thermometer designed for K-type thermocouples, capable of measuring temperatures from -50°C to +1300°C (-50°F to +1999°F). It features selectable resolution (0.1°/1°) and user-selectable units (°C/°F), making it flexible for both industrial and laboratory applications. The device supports single-channel input (TES-1300) or dual-channel input with differential measurement (TES-1303), allowing simultaneous monitoring of two points with T1-T2 comparison.

Equipped with auxiliary outputs for data recording, a data hold function, and a flip-up stand, the thermometer is convenient for continuous measurements and analysis. Its durable design, powered by a 9V battery, provides long-lasting operation (100–200 hours), while clear LCD readings and room temperature compensation enhance accuracy and usability across varied working conditions.
