BB Series
The BB Series is a constant low temperature water bath line from Yamato Scientific offering precision control to ±0.1°C across an operating range of -30°C to +80°C.
Manufacturer: Yamato — Japan
Overview
The BB Series is a constant low temperature water bath line from Yamato Scientific offering precision control to ±0.1°C across an operating range of -30°C to +80°C. The bath includes an external circulation function with an easily operated water valve for switching between internal and external circulation, and its shelf plates can be height-adjusted across three sections to accommodate small vessels. Auto stop and auto start operations are supported, along with an RS485 communication function and a temperature output terminal (4 to 20mA). The series includes three models, BB301, BB401 and BB601, of increasing capacity.
Precise Low Temperature Control
The bath offers precise control with a temperature control accuracy of ±0.1°C.
Internal and External Circulation
The bath has an external circulation function, and the water valve can be easily operated to switch between internal and external circulation.
Adjustable Shelf Plates
The shelf plates' height can be adjusted across three sections, accommodating small vessels.
Communication and Auto Operation
The bath supports auto stop and auto start operations, auxiliary with RS485 communication function and a temperature output terminal (4 to 20mA).
