Manufacturer: Yamato — Japan
Overview
The BOA Series is a large-capacity oil bath line from Yamato Scientific designed for use inside a fume hood, with tank capacities up to 37L. Each unit achieves high-temperature distribution accuracy through a jet stirring method and is equipped with six safety functions, including a triple overheating prevention function, an emergency stop switch, and float switches to prevent empty heating and oil overflow. Support functions include an external alarm output, a temperature output terminal, RS485 communication, a key lock function, and calibration offset, all standard equipment. The series comprises two models, BOA201 and BOA311, which differ in power supply current.
