the safety thermostat will cut the mains supply
Circulation pumping device
The bath is equipped with a special stirrer-pump combination which ensures a good uniformity.
Condensation prevention
To prevent build up of condesat onto the cold surface of the window, surface heaters have been installed
around the window.
A temperature sensor on the window keeps the surface temperature of the window just above the dew-point
under ambient conditions of up to 40
°
C and 85% RH.
Illumination
An illuminator providing diffused fluorescent light for background lighting is mounted on the roar of the bath. It
can be switched on and off with the switch-lamp on the control panel.
Top plate
The bath is supplied with a round lid with 3 holes 50 mm diameter to accept 3 capillary type viscometers in
holders. Behind each viscometer position there is an opaque glass plate for easy reading of viscometer.
Installation
Tamson baths are carefully packed when they leave the factory to avoid damage during transport.
Check the packing for any external damage and make a note on the shipping documents if any damage is
found. Always retain the cartons and packing material until the bath has been tested and found in good
condition, because transport companies generally will not honour a claim for damages if the respective
box(es) is (are) not available for examination.
- Clean inner bath thoroughly of any loose packing materials etc.
- Place the bath in a level position.
- Check operating voltage (230 V or 115 V) and connect the bath to appropriate mains supply. The bath has
to be filled with a liquid suitable for operating temperature.
WARNING:
Never operate the bath without fluid !!!!
Filling and Bath liquids
Fill the bath up to 5 -10 mm below the lid. At no time should the bath level be allowed to fall 60 mm of the top
plate. Depending on the bath temperature we advise the use of methanol as bath fluid.
Use a mains supply that is well earthened and clean of interferens and can carry
the load of the bath. Be sure to check the power requirements (230V / 115V)
marked on the tag plate at the back side of the bath.
When using a Cryostat KV80 or KV40, the use of the mixture water
and ethyleneglycol is not recommended because of the high capacity of the cooler.
(ice will grow on the evaporator causing poor heat exchange and unstable
temperature control
