Low temperature constant temperature water bath BBL111C/311C
Low temperature constant temperature water bath BBL111C/311C
Product details

BBL111C/311CLow temperature constant temperature water bath

Temperature range -10~+80 ℃, temperature distribution accuracy ± 0.3 ℃, content volume 8L 13L

The tabletop low-temperature constant temperature water bath ensures a wide temperature range and sufficient sink space.

Characteristics

It can achieve precise control of temperature regulation accuracy within ± 0.1 ℃.

Expanded the purpose of the sink itself, fully ensuring the effective space inside the sink.

Equipped with external loop function.

The switching between internal and external circulation can be achieved by simply operating the water valve.

The height of the shed board can be adjusted in two sections, even for small containers.

The main functions are automatic stop and start, with RS485 communication function and auxiliary functions such as temperature output terminal (4-20mA) as standard equipment.

Security

Self diagnostic function, leakage protection switch to prevent overcurrent, freezer pressure detection, float switch to prevent air burning, freezer overload protection relay, and freezer protection delay function.
