Food, Drink, Body Weight

For Continuous Uninterrupted Monitoring of Intake and Weight Changes

The weight sensor of the PhenoMaster

Mastering Ingestive Behavior and Body Weight with Precision

The PhenoMaster highly sensitive weight sensors are interchangeable and allow researchers monitoring ingestive behavior and body weight with exceptional detail. Positioned outside the cage, they minimize disruption during refilling and animal handling.

Unmatched Flexibility and Data Integrity:

  • Adaptable Configurations: Mix and match sensors for a variety of research protocols.
  • Spill & Leak Protection: Our exclusive technology safeguards against data skewing due to food spillage or water leakage.
  • Automatic Monitoring: Track food, drink intake, and body weight continuously for extended periods, eliminating manual intervention and potential bias.
  • Modular Design: Integrate up to four sensors per cage to tailor your research needs.

Key Features

High-precision sensors, capturing micro events

Small and light plug-in sensor design assembly and easy refill with fresh water and food

Validated Spillage and Leakage protection

Validated for temperature challenges

Multiple sensor configurations for mice discrimination experiments

Full resolution data storage in a raw format

Automated Access Control

Experience precise control food/liquid Access Module. Restrict consumption based on time, amount, or averaged consumption of a control group or individual. The PhenoMaster stands out as the only system offering interchangeable access-controls for food hoppers and water bottles, enhancing flexibility for study designs.
