Product Description


Test Methods:
ASTM D445 Standard Test Method for the determination of kinematic viscosity
ISO3104 Petroleum products – determination of kinematic viscosity
IP 71 Part 1 Kinematic Viscosit

Easy to Use
The TCB-7 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 7 viscometers, which can be placed in the bath simultaneously.

Built in cooling coil
The TCB-7 bath can be used from 15 to 150°C, and is supplied with a built in cooling coil. Operation at temperatures from 15ºC to 40ºC  require an external source of chilling. This is provided by a cool liquid, which is passed though the cooling coil.  A recirculating chiller is available from PSL to provide the cooling required. 

Stability Certificate
All TCB-7 baths are supplied with a certificate of  temperature stability and uniformity. Excellent circulation technology provides superior uniformity.
