The BA/BK models are deep constant temperature water baths.

The BK model enables fixed operation, while the BA model allows for programmed operation. For each model, there are five kinds of tank capacities: 27L, 42L, 70L, 109L, and 144L.

An extremely high degree of temperature adjustment precision is achieved by using a high-precision thermostat and circulation pump.
Settings for the temperature and timer can be easily input using the up and down keys, and the settings appear on a digital display.
