Multi Lead Expandable Several options are available depending on the research protocol and the need to acquire other signals (pressure, volume, flow, etc.) in addition to ECG. Our multi-channel systems have software configurable gains, high-pass and low-pass filter settings. These systems allow for simultaneous recording of up to 12 ECG leads (lead I, lead II, lead III, aVR, aVL and aVF and the 6 chest leads). |


Fluid-Filled Catheter System
The BP-100/102 blood pressure transducer is an economical and accurate device used to measure direct arterial or venous pressure in animals using the fluid-filled catheter technique. A precision laser-trimmed chip provides accurate and linear measurements over a broad range of pressures. Pressure changes in the vessel are transmitted within the fluid-filled tube to the pressure transducer and acquired for monitoring and further analysis. Tubing is available as small as 1 mm in outside diameter making this technique well-suited for measuring pressures in very small vessels. Blood pressure systems include the transducer, cable, data recorder and software.Bladder Pressure
The BP-100/102 blood pressure transducer can also be used to measure bladder pressure.Complete System | |
