Cooling thermostatic bath AT-1260

automaticfor heatingwith temperature control

The AT-1260 is a large-scale seawater temperature bath developed by MPtest specifically for the verification, calibration, and metrological traceability of oceanographic Conductivity-Temperature-Depth (CTD) sensors and complete sensor frames. The bath is constructed of titanium alloy and uses seawater as the working medium. It features a workspace with a diameter of 660 mm (26.0 inches) and a depth of 1250 mm (49.2 inches), with a total volume exceeding 500 liters (132 US gallons). The substantial depth of nearly 1.25 meters allows entire CTD frames to be immersed for calibration and traceability. A built-in thermostatic enclosure minimizes the influence of ambient temperature fluctuations. Combined with MPtest's jet-stream agitation technology and a high-precision temperature control system, the bath achieves a temperature stability of ±0.0003°C at 2°C. The use of an external split cooling/heating unit (heat pump) accelerates heating and cooling rates, improving operational efficiency. It is suitable for comprehensive testing of oceanographic CTD systems and for use by research and development departments. - Operating Temperature: Seawater: -1.5 ℃ to 50 ℃ (29.3°F to 122°F); Seawater Salinization: -5 ℃ to 50 ℃ (23°F to 122°F) - Working Area: Diameter 660mm (26"), Depth 1250mm (49.2") - Wetted Parts: Titanium Alloy - Liquid Volume: Approximately 500 liters (132.1 gal) - Stirring Method: Jet stirring, three-speed adjustable - Temperature Control Method: Fully digital PID control - Display Resolution: 0.0001 ℃ - Temperature Stability: ±0.0003 ℃ /10min at 2 ℃ (35.6°F) to 35 ℃ (95°F) - Temperature Uniformity: ±0.0005 ℃ at 2 ℃ (35.6°F) to 35 ℃ (95°F) - Heating Time: 60 minutes from 25°C(77°F) to 40°C(104°F) - Cooling Time: 90 minutes from 25°C(77°F) to 5°C(41°F) - Operating Voltage: Industrial Three-Phase 208VAC ±10%, 60Hz (Star Wiring) - Rated Power: Approximately 8000W - Dimensions: 790mm (31.1") x 910mm (35.8") x 1800mm (70.9") - Net Weight: Approximately 180 kg (396.8 lb)
