Precise Seawater Bath
The AT-5100 is specifically designed for the calibration and value transfer of ocean environment sensors. Its titanium alloy bath uses seawater as the working medium, featuring a workspace diameter of 550 mm (21.65 inches) and a depth of 380 mm (14.96 inches). Equipped with an integrated thermostat to mitigate ambient temperature effects, combined with MPtest's jet-stream agitation technology and a high-precision temperature control system, it achieves a stability of ±0.0005°C at 2°C. The system incorporates MPTest's proprietary rapid-cooling technology, enabling swift temperature reduction. It is ideal for ocean sensor manufacturers requiring batch calibration of multiple probes simultaneously, as well as for R&D departments demanding ultra-stable conditions for technical development.
