Product Information

We are currently developing an automated device PD-Auto, where stacks of 15 AST agar plates can be placed. The PD-Auto will automatically take photos of the AST plates and the results will be displayed in the software as in the PD-100 today.

The PD-Auto will be ready for sale within a few months.


PD-100 is a small size equipment that easily and automatically reads and calculates inhibition zones for measuring resistance using the disc diffusions test. PD-100 ensures uniform measurements and a high degree of traceability.


  • Standardised reading
  • Uniform measurements
  • Facilitates workflow
  • Free up time for other work tasks
  • Increases capacity
  • Ensures photo documentation and traceability
  • No limitations on the number or position of discs
  • Easy implementation of quality standards
  • Electronic circular “ruler” makes measurement easier and increases quality
  • Flexibility – PD-100 can be adapted to your specific needs and requirements (customised base-plate and customised antibiotic database)
  • A good ergonomically alternative to manual measurements


  • Quick visual presentation of results
  • Automatic suggestion of zone edge presented by green circle
  • Automatic suggestion of inhibition zone size
  • Possibility to manually adjust zones
  • Automatic presentation of results listed by zone size
  • Automatic text reading and identification of antibiotics
  • Handles both round and square petri dishes
  • Full traceability & documentation
  • Plug and play installation
  • User friendly software
  • Data documentation can be transferred to other systems


  • Size: 19 x 19 x 21 cm
  • Weight: 5 kg
  • Danish design
  • Small and handy
  • Easy to operate
  • Robust quality
  • Easy to move
  • Advanced 5MP camera
  • Low power consumption (5V)
  • 1 standard USB-cable
  • Easy to clean design
  • Easy to maintain
PD-100 can assist professionals in the busy laboratory. in few seconds are the inhibition zones measured and the result saved. This ensures uniform measurements and traceable documentation. Offering early treatment with specific antibiotic drugs, increases patient safety and prevents the development of bacterial resistance.

Increased quality assurance
Traceable documentation
Improved ergonomics


PD-100 has been tested and validated in cooperation with Hvidovre Hospital.

Inhibition zones for gram positive and gram negative bacteria were measured by PD-100 and by manual measurement respectively. The average conformity of the two different methods were calculated and compared. The results showed an average conformity of 99 % for the gram positive bacteria and 96 % for the gram negative bacteria.

The identification of the antibiotic discs is done 99% certainty.

More test-results are coming.
