The PSL Coldfinger CF 15120 is equipped with up to 15 measuring places for multi-place testing. Combining multiple cold fingers in one heating bath facilitates screenings on wax inhibitors, e.g. simultaneous testing of different chemicals on a single sample or testing of different inhibitor concentrations with the same sample. The Cold Finger can be run with separate temperature control and stirring speed for each rack of 5 measuring places, thus reducing full test procedure for a single sample immanently. The dry bath allows a precise temperature control up to +120 °C / +248 °F.


The Differential Dynamic Scale Loop (DSL) by PSL Systemtechnik as a fully automated laboratory device is a tube blocking system to examine the precipitation and deposition of scale and other salt crystals in pipework systems like oil or water pipelines.


The Dynamic Stability Loop (DySL) by PSL Systemtechnik was designed to test long-term stability of umbilical chemicals in the lab at very stringent conditions. The DySL combines up to six loops for measurements of long-term changes of viscosity and tube blocking tendencies at pressurized conditions.

Oil Airation Machine (Foam)

Our FOAM (Flucon Oil Aeration Machine) is a compact aggregat which contains a 40 Liter tank (type FOAM S), that can be easily integrated into your fluid circuit as a reservoir, where it then produces consistent air-in-oil dispersions. If you favor an external installation, with an aeration unit added to your pre-existing open reservoir, you may prefer our FOAM XL-x, which we also recommend if higher flow rates of up to 60 l/min (15 gpm) of aerated oil are required. If you need even more than that, we also offer extra-large custom FOAM units. No matter what type of FOAM you prefer: Aeration testing is very easy with this plug-and-play unit. Simply set up a gas concentration (CG set = 0.50 – 25.00 vol.-%*) for your specific oil. The FOAM will immediately add the desired amount of dispersed gas to your fluid. This procedure will be carried out fully-automatically, with no compressed air supply required. When the gas concentration reaches the required level the “FOAM ready” lamp lights up and you can go ahead and pump the aerated oil through your circuit.


The portable H2S Analyzer 320 (DyMS) was developed for determination of H2S content in bitumen, asphalt, crude and heavy oils and refinerey products. The measuring method of the H2S Analyzer 320 (DyMS) allows accurate measurements in liquid and gas phase.


High-Pressure High-Temperature Viscometer PSLs latest product is the High-Pressure High-Temperature Viscometer (HPHT viscometer). With this rotational viscometer the viscosity of shear rate-dependent (newtonian) fluids as well as the viscosity of shear rate independent (non-newtonian) fluids can be measured under pressures of up to 1,500 bar (21,750 psi) and temperatures up to 200 °C (392 °F).


The portable Pour Point Tester PPT 45150 by PSL Systemtechnik is a compact lab instrument to measure the no-flow point and calculate the pour point of oils and oil products. The PPT 45150 measures according the rotational method ASTM D5985.

CGS Inline Aeration Meter

The CGS (Concentration Gas System) is an inline measuring system for the continuous determination of the gas content in fluids. The system works regardless of the size and shape of the entrained gas portions in the fluid. Therefore both finely dispersed microbubbles as well as large air pockets can be detected correctly in the passing medium, with their percentage by volume displayed in real time. The following parameters are determined by the CGS: • temperature (−30 °C to 150 °C) • pressure (max. 10 bar) • gas content CGp at measured pressure • gas content CG0 at atmospheric pressure (recalculation according to the ideal gas law)

E-Lub Tester

The E-Lub Tester determines the ohmic resistance and capacitance of your rolling bearing, thus of the lubricant used therein, under real operating conditions applied by the FBT four-ball tester. For this, a high-precision impedance measurement is used, which was developed based on flucon's EPSILON+ laboratory instrument. In addition, the E-Lub Tester enables EDM breakdown currents to be analyzed under a defined electrical load on the bearing so that the performance of greases and oils in rolling bearings can be specifically investigated under variable operating conditions (lubricant temperature, speed, load).  

Key features

  • determination of the lubricant impedance in rolling bearings
  • suitable for axial roller bearings (type 51208) and radial ball bearings (type 6008)
  • determination of ohmic resistance and capacitance
  • EDM analysis (short-circuit-Scan): measurement of electrical breakdowns and ohmic currents during operation
  • variable operating parameters: E-Lub Tester: lubricant temperature (automatic control), electrical load (common-mode voltage); FBT: running time, speed, load (all relevant data is stored in the program)
  • automated measuring programs
  • includes intuitive software for control and measurement with a Windows PC
  • includes impedance calibrator

EPSILON+ for the measurement of dielectric fluid properties (Conductivity, Permittivity, DDF)

EPSILON+ is a compact laboratory measuring device that is used for the precise measurement of the complex fluid impedance, based on DIN IEC 60247 (own DIN test standard coming soon). This reliable system determines the following parameters:
  •  Specific Electrical Conductivity
  •  Relative Permittivity / Dielectric Constant   ε r
  •  Dielectric Dissipation Factor (DDF) tan δ

EPSILON+  //  Measurement

EPSILON+ is characterized by its operator convenience. Less than 10 ml fluid quantity are sufficient for the measurement set-up of the screw-in sensor. The sample is filled into the supplied stainless steel container and heated up to the desired test temperature by means of a thermostat (optionally available). Automatic measurement can be conducted as well within a desired temperature range, with increments of your choice.
