Ultra-Precision Seawater Bath
The AT-1000 is specifically engineered for the calibration and value transfer of oceanographic sensors. Its titanium alloy bath uses seawater as the working medium, featuring a workspace diameter of 550 mm (21.65 inches) and an exceptional depth of 900 mm (35.43 inches). The near-1-meter bath depth enhances temperature stability performance, while the integrated thermostat minimizes environmental temperature interference. Combined with MPtest's jet-stream agitation technology and a high-precision temperature control system, it achieves a temperature stability of ±0.0003°C at 2°C. Equipped with MPtest's proprietary rapid cooling technology, the bath enables fast temperature reduction, making it ideal for high-throughput calibration of multiple probes in marine sensor manufacturing and R&D applications.
