Portable Seawater Bath

This device is a precision thermostatic bath constructed with titanium alloy, specifically designed for mobile metrology of marine temperature sensors (CTD), using seawater as the working medium. It features a workspace with a diameter of 138 mm (5.4 inches) and a depth of 500 mm (19.6 inches), combining a compact, lightweight portable design with an integrated thermostat to mitigate ambient temperature interference. Equipped with MPtest's jet-stream agitation technology and a high-precision temperature control system, it achieves a temperature stability of ±0.001°C at 2°C. The bath includes an electrical measurement channel compliant with ITS-90 standard platinum resistance thermometers, enabling on-site temperature traceability. Additionally, it incorporates MPtest's proprietary rapid-cooling technology to ensure swift temperature reduction and stable operation in complex environments.
