Product Description


The Visibility bath is very easy to operate. Using the touch pad on the control unit, the set-point is keyed in. The set-point can be programmed and calibrated to two decimal places. Thermometer holder for precision thermometer is built in. Safety features include a  low liquid level switch, an upper temperature limit warning, a low temperature limit warning and a high temperature cut-out device.

Excellent Visibility
The bath construction affords full visibility of up to 4 viscometers, which can be placed in the bath simultaneously.

Simple Design
An advantage of the single walled design is that the Visibility Bath displays excellent temperature stability at 40 degrees C without the use of an external chiller. This makes the Visibility Bath an excellent choice for testing the Kinematic Viscosity of Biodiesel for product specification.

Built in cooling coil
The Visibility bath can be used from 20 to 60°C, and is supplied with a built in cooling coil. Operation at temperatures below or near ambient  require an external source of chilling. This is provided by a cool liquid, which is passed though the cooling coil.  A low cost recirculating chiller is available from PSL to provide the cooling required. The PSL-Rheotek Chiller is specially designed for operating with the TCB-7MkII bath.

Stability Certificate
All Visibilty baths are supplied with a certificate of  temperature stability and uniformity. Excellent circulation technology provides superior uniformity of temperature in the Visibility Bath.
