  • IUL - Haloes Caliper

Making a precise inhibition zone measurement (100 µm resolution) manually can become a challenge.

The Haloes Caliper helps to perform this in a simple and precise fashion while avoiding parallax errors in readings. Pharmaceutical and clinical labs involved in inhibition zone measurements benefit from the use of this device. A precision rotating wheel accurately measures inhibition zones while being manually spun. This comes in handy during antibiotic susceptibility testing and antibiotic potency measurements.

System Highlights

  • High resolution: The Haloes Caliper has a 100 µm resolution.
  • No parallax error: The Haloes Caliper’s exclusive screen-lense system avoids missing the ends of the haloes through its unique perpendicular reading technology.
  • Clear display of results: Results will be clearly featured in a digital display.
