Fully-automatic system - ASTM D1120

The system is designed for fully-automatic operation conforming to ASTM D1120 to determine very precisely and reproduceably the boiling point of engine coolants and brake fluids according to SAE-J1704 and other standards

A complete test can be done in approx. 8-15 minutes.
An indelible print out with all results is peformed automatically and additionally a PDF-file can be created for network connectivity.

The product is being charged and heated up to the boiling point. The drop rate of the condensed product is being detected and registered by means of an optical sensor. Up to the point when the optimal and preselectable drop rate per second is achieved the system will control the heating power by pulse duration modulation.
The system controls the operation until the required equilibrium is stabilized. The temperature of the liquid is being measured by means of of very precise temperature sensor.

By using a barometric sensor the boiling point correction is being calculated and presented via a programmed formula. All parameters are variable in order to follow different applications and test procedures in the same system.

PILODIST 1120 CC can be operated in different measuring modes to be selected via an integrated touchpanel.
All parameters are indicated during the measuring process as well as the results.

The basically included test methods are:
• REFLUX BOILING POINT (ASTM D1120)
• EQUILIBRIUM REFLUX BOILING POINT (SAE-J1704)

As a special feature there is an additional software available for measurements also the following characteristics according to SAE-J1703 & J1704 (Option 1):
• WET BOILING POINT
• CHEMICAL STABILITY
• HIGH TEMPERATURE STABILITY

All methods are also valid for the test standards:
• ISO 4925
• FMVSS 116


The software is easy to operate and self explaining. In a password protected service area all parameter recipes are saved by a supervisor and loaded by the operator in an different access modes.
The software provides in the password-protected area the possibility of a 2-point calibration of all sensors.
A network connectivity is given to transfer results to other PCs and for PILODIST remote support.
