Plethysmometer (Paw Volume) Meter ● No wetting solution needed ● One calibration/year ● Battery-operated or line powered controller ● One-year warranty Test the effectiveness of anti-inflammatory agents and agents to reduce edemic conditions with the Plethysmometer. Simply insert the rat or mouse paw into water. A sensor in the water notes a pressure change when the paw is immersed. Pressure is calibrated in 0.1 milliliters and displays on the battery-powered monitor. The acrylic stand offers full visibility of the subject throughout the testing. II-520MR Paw Volume Meter for Mouse & Rat ANIMAL SURGERY & SUPPORT Randall Selitto Paw Pressure Meter ● Hands free operation with footswitch ● Visible force limit indicator ● Portable electronic display ● Battery-operated or line powered controller ● 3-oz. handheld probe with accuracy of 0.5% ● No calibration required The Randall Selitto Paw Pressure Meter for analgesia testing is digitally controlled. Use the handheld instrument to apply force to an animal’s extremity and get instantaneous, live readings. You can even view the last maximum force applied during the test. The new limit II-2500 indicator lets you select the maximum force limit, and then indicates with a warning light when the system reaches that limit. This unit comes with an acrylic stand to allow for easy viewing of the display. Stand and sling are sold separately. Randall Selitto Paw Pressure Meter, 800 g pressure applicator Grip Strength Meter ● Mouse and rat wire mesh grid plates included ● Maximum force range is 2,000 gm (10% over range allowed). Higher ranges are available by special order. ● 1 gram increment readings ● Suction feet on the heavy, anodized base plate resist even large pulling forces ● Battery-operated or line powered controller ● One year warranty Measure muscle hyperalgesia in rats and mice with the Grip Strength Meter, which gauges the forelimb grip force using a digital force transducer. Simply hold the animal by the tail and gently dangle it over the wire mesh plate until the animal grasps the plate with its forepaws. The force transducer, connected with the wire mesh plate, measures the strength of the animal at the time of the test. The battery-operated, electronic control device Grip Strength Meter for Mouse & Rat calculates the average of three measurements, and it holds the last maximum force in a “peak and hold” type readout until you reset it.
