DTZ-400BG Surface Probe Temperature Calibrator (35℃ to 400℃)

    The DTZ-400 surface probe calibrators feature a large 130 mm flat calibration surface and are designed to calibrate a wide range of surface sensors of various shapes and sizes, including L-shaped sensors, thermistors, thin-film sensors, surface RTDs, ribbon sensors, and surface thermocouples. Each calibrator consists of a controller and a heating block, offering intuitive operation with quick temperature setup and fast, stable heating. They are equipped with multi-segment PID control and an RS-232 interface for connection to a PC. With minor modifications, the calibrators can be upgraded into blackbody sources for calibrating infrared thermal imagers.

· Wide temperature range and multiple models are available: 35 °C to 400 °C, 50 °C to 500 °C, and 50 °C to 600 °C ranges.

· Large 130 mm calibration surfaces are ideal for various sensor types and calibration procedures, such as L-shaped sensors, thermistors, thin-film sensors, surface RTDs, ribbon sensors, and surface thermocouples, etc

· Accuracy is high: ≤ ±0.5 °C at 200 °C.

· Fast heating and cooling: temperature rises from room temperature to 400 °C in just 30 minutes; optional fast-cooling setup brings 400 °C down to room temperature in 45 minutes.

· Excellent stability: ±0.3 °C / 10 min at 300 °C.

· High resolution: 0.01 °C temperature display resolution.

· Multi-segment PID control: customizable for high, medium, and low temperature zones.

· Aerospace-grade surface coating: coated with a high-hardness, high-wear-resistance, high-thermal-conductivity aerospace composite.

· Grooved design: accommodates L-shaped surface sensors for accurate placement during calibration.

· Reference probe socket: a built-in insertion port below the surface center allows placement of a precision RTD as a reference standard, improving calibration accuracy.

· An RS-232 communication interface is supported.

· Uniform surface temperature and smooth finish: the aluminum block provides high flatness and surface finish, ensuring optimal thermal contact with surface sensors. This minimizes measurement uncertainty during calibration.

· Accurate and stable temperature control: minimal overshoot with user-defined PID parameters and alarm settings for different temperature ranges.

· Portable and user-friendly: compact and lightweight design, with total system weight of only 12 kg.
