 Temperature range of circulation jacket and thermostatic flow conditions: 
 

 

Permitted temperature range: -10 a +100°C (14 a 212 °F) 

 

Use  a  thermostatic  bath  with  demineralised  water  or  refrigeration  special  liquid.  Change  the  liquid 
form the thermostatic bath regularly. Recommended flow: 15 l/min. 

 
Materials: 

 

 

The metallic parts are made of stainless steel; the lids are made of plastic in Delrin. The parts in contact 
with the sample (sample container and spindle) are made of AISI 316 suitable for food industry. 

 

The lid inferior washer is made in black Delrin. It is designed to get a maximum temperature of 100ºC (212 
ºF) 

 

The circulation jacket is made of acetal and Delrin.  

 

The O-ring on the plastic stopper (M) of the APM Adapter is made of Delrin.  
The softening point is 110 °C (230 °F).  

11.3 HELDAL UNIT – Helicoidally Movement Unit 

NOTICE: 
 
The  Heldal  adapter  it’s  not  included  in  the  standard  delivery.  It  can  be  ordered  as  an  accessory.  The  unit  is 
supplied complete with T-shaped spindles, in this case. 
 
The  Heldal  accessory  is  used  with  substances  that  do  not  flow  by  themselves  (like  ice  or  pastas).  It’s  motor 
moves  the  viscometer  slowly  in  a  vertical  movement  and  at  the  same  time  the  spindle  makes  the  rotation 
movement.  This  generates  a  helicoidally  movement  so  the  T-shaped  spindle  is  always  in  contact  with  the 
sample. 
 
The  measurements  obtained  with  Heldal  do  not  measure  absolute  viscosity!  They  are  only  comparative 
measurements with the same geometry as T-shaped spindles.
