These sensors are available in different sizes and shapes to best adapt to the size of your animals as well as to your experimental constraints.
For mice:
- Thigh sensor provides a strong signal from the femoral artery
- Paw sensor avoids shaving animals for quick measurement. It can also be used to get measurements from a mouse tail
- Throat sensor provides vital sign measurements from an anesthetized animal lying on its back by obtaining a strong signal from the carotid arteries
For rats:
- Paw sensor allows quick measurement over a beardless area
- Throat sensor provides a strong signal from the carotid arteries
Following is the sensor sizing chart. To get ACCURATE MEASUREMENTS, it is imperative that you follow this chart when choosing a sensor for a given animal.
Size | Unshaven mouse | Shaven mouse | Rat |
XS (collar or throat) | 1-15 g | 1-20 g | N/A |
S (collar or throat) | > 15 g | > 20 g | 5-30 g |
M (collar or throat) | N/A | N/A | 31-100 g |
L (collar or throat) | N/A | N/A | 101-300 g |
XL (collar or throat) | N/A | N/A | 301-500 g |
2XL (collar or throat) | N/A | N/A | > 500 g |
Thigh | < 60 g | < 60 g |
≤ 100 g |
Foot | N/A | N/A | > 100 g |
Paw | > 5 g | > 5 g | N/A |
These sensors are designed to provide the highest quality measurements.
To assure the highest level of accuracy it is recommended that you replace each sensor after 100 hours of use.
Each sensor is shipped with a “Handle Support” in place across the finger tabs to prevent plastic deformation that can accumulate over long periods of time. When not in use always store the sensors with the handle clamp in place.
