The DTWL high-precision temperature calibration chamber is a specially designed air-based thermostatic chamber, offering high temperature control accuracy, excellent temperature uniformity, and minimal fluctuation. Many temperature-measuring instruments and sensors cannot be calibrated using liquid-based temperature sources and are unsuitable for calibration in temperature calibration baths. The DTWL high-precision temperature chamber addresses this issue, filling a critical gap in precision temperature sources, and providing a complete calibration solution for temperature measurement instruments.

Features

High-resolution touchscreen
