The DTW high temperature smart calibration salt bath is a newly developed product designed to meet the calibration, validation, and verification requirements of temperature sensors. Structurally identical to standard laboratory oil baths, it features an independent heating system, stirring system, and a high-precision temperature control system (accuracy up to 0.1 grade). This bath provides a stable and precise heat source with a non-pressurized, non-toxic, and non-corrosive bath liquid. The bath's insertion port diameter can be customized as needed, making it ideal for high-precision testing of thermocouples and resistance thermometers.

Product Features

Linear temperature control

The salt bath supports linear heating at a specified rate, meeting the calibration, validation, and verification requirements of various temperature switches.

Multi-point calibration & correction

Temperature is corrected segmentally, with automatic linear fitting between set values (SV) and process values (PV). Temperature points are PID controlled segmentally and saved automatically to ensure precise temperature control at any setpoint.

Automatic temperature control

Heating and stirring are fully automatically controlled, eliminating the need for manual operation.

Scheduled salt melting function

The bath supports automatic startup, shutdown and salt melting at set time, improving operational efficiency.

Comprehensive communication support

Smart models support USB, Wi-Fi, WLAN, and serial communication, enabling data upload and export.

Smart large touchscreen control

A large capacitive touchscreen is embedded with intuitive operation system The smart interface supports multi-function window displays. Real-time stability and temperature control curve are calculated and displayed. Multi-touch supports for free zooming and panning.

Language and units

The system supports English and Chinese interfaces. Temperature units can be switched between Fahrenheit (°F), Celsius (°C), and Kelvin (K).

Dual independent protection circuits

Dual independent protection circuits automatically cut power in case of overheating, providing enhanced safety.
