High-temperature calibration bath GD-2500S

for thermometers

Mptest specializes in the manufacture of fixed-point cells and realization apparatus for temperatures defined by the ITS-90. The GD-2500S is a realization apparatus specifically designed for the zinc freezing point. This system features a temperature control stability of ±0.02 °C and is equipped with a bath boasting an aperture of 63.5 mm. The temperature controller incorporates a color touchscreen interface, which allows for the input of Standard Platinum Resistance Thermometers (SPRTs) and provides a real-time curve display for observing the temperature plateau. It also includes a rate-controlled heating/cooling function to prevent excessively fast temperature ramps. The bath employs a metallic construction paired with a heat-transfer sleeve to ensure optimal thermal conductivity. This key design effectively suppresses overheating, thereby safeguarding the valuable fixed-point cell and ensuring the integrity of its performance. - Operating Temperature: 50 ℃ to 450 ℃ (122°F to 842°F) - Working Area: Diameter 63.5mm (2.5"), Depth 350mm (13.8") - Trough Material: Aluminum - Temperature Control Method: Fully digital PID control - Display Resolution: 0.01 ℃ - Display accuracy: ±0.1 ℃ - Temperature Stability: ±0.02 ℃ /10min - Axial uniformity: ±0.3°C at 420°C (150mm in the Vessel) - Heating Time: 30 minutes from 25°C(77°F) to 430°C(806°F) - Stabilization Time: 20~30 minutes - Operating Voltage: 110VAC±10%, 60Hz (Customizable Technical Specifications) - Rated Power: Approximately 1200W - Dimensions: 405mm (15.9") x 350mm (13.8") x 870mm (34.3") - Net Weight: Approximately 40 kg (88.2 lb)
