Compact calibrator GD-1189S

fully-automatichigh-temperaturelow-temperature

The GD-1189S is a compact and user-friendly apparatus designed to achieve an argon triple-point reproducibility of within ±0.5 mK. Its design eliminates the need for a helium-filled standard platinum resistance thermometer (SPRT), significantly simplifying the operational procedure and reducing the risk of damaging the thermometer. Furthermore, the apparatus incorporates a unique structural design that prevents the thermometer from freezing in place due to atmospheric condensation, while also addressing the material and structural challenges associated with the high-pressure container. Utilizing 6N high-purity argon gas, the system allows for the calibration of at least 6 to 9 thermometers at the low-temperature argon point through multiple freeze-thaw cycles. The unit is equipped with an appropriate temperature control system and a physical liquid level indicator, enabling convenient monitoring of the liquid nitrogen level. - Operating Temperature: -189.3442 ℃ - Working Area: Conical Structure, 4-Hole*8mm (0.3"), Depth 350mm (13.8") - Temperature Control Method: Fully digital PID control - Display Resolution: 0.001 ℃ - Temperature Stability: ±0.010 ℃ /10min - Temperature Uncertainty: ±0.5mK (Calibration Options: k=2) - Plateau Duration: 2 Hours (Allows for repeated freezing cycles) - Operating Voltage: 110VAC±10%, 60Hz (Customizable Technical Specifications) - Rated Power: Approximately 150W - Dimensions: 408mm (16.1") x 280mm (11") x 635mm (25") - Net Weight: Approximately 15 kg (33.3 lb)
