High-temperature calibration bath GD-2200S

for thermometers

Mptest specializes in the manufacture of fixed-point cells and realization apparatus for temperatures defined by the ITS-90. The GD-2200S is a realization apparatus designed specifically for the indium freezing point. This system features a temperature control stability of ±0.02 °C and is equipped with a bath featuring a 63.5 mm aperture. The temperature controller incorporates a color touchscreen interface, which allows for the input of Standard Platinum Resistance Thermometers (SPRTs) and provides a curve display function for observing the temperature plateau. It also includes a rate control function to prevent excessively fast heating or cooling rates. The design utilizes a metallic bath coupled with a heat transfer sleeve to ensure optimal thermal conductivity. This key feature effectively suppresses overheating, thereby safeguarding the valuable fixed-point cell and maintaining its measurement integrity. - Operating Temperature: 50 ℃ to 200 ℃ (122°F to 392°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 156°C(150mm in the Vessel) - Heating Time: 15 minutes from 25°C(77°F) to 200°C(392°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)
