flucon's latest innovation:
EPSILON+ Dielectricity Meter
EPSILON+ is a compact laboratory instrument for precise measurement of the complex fluid impedance according to DIN 51 111. This test standard was based on DIN IEC 60247 and specifically developed for moderately conductive lubricants. It allows for a non-destructive analysis using AC voltages.
This reliable system will determine the following properties:
- Specific Electrical Conductivity
- Relative Permittivity / Dielectric Constant ε r
- Dielectric Dissipation Factor (DDF) tan δ
EPSILON+ | Measurement
EPSILON+ is characterized by its operator convenience. Only 8 ml of fluid are required inside the test cell which consists of a stainless steel screw-in sensor. The sample is filled into the additional cup and heated up to the desired test temperature by means of a thermostat (different options available). Automatic tests can be conducted within a desired temperature range, with increments of your choice.
EPSILON+ | Features
- dielectric fluid testing by means of impedance measurement in accordance with DIN 51 111 (sole instrument of standardization)
- determination of specific electrical resistivity/conductivity, dielectric constant and DDF
- only small sample amounts required (8 ml)
- high accuracy and repeatability
- wear-free test cell (stainless steel screw-in sensor and sample cup)
- integrated PT100 temperature measurement
- optional thermostat for automatic sample temperature control
- compact tabletop unit with aluminum housing, TFT display and menu knob
- EPSILON+ PC software for control and measurement evaluation included
Optional thermostat for automatic sample temperature control
We also offer different suitable thermostats, which can be controlled automatically by the EPSILON+ device and quickly set up whatever sample temperature you desire for your tests:
- Dry-block thermostat (standard for DIN 51 111, as shown below): room temperature to 180°C
- Julabo fluid circulator with heat exchanger vessel for additional cooling: -20°C to 180°C
E is for enhancement.
