The Rat Biopotential Telemeter measures the biopotential difference between the two electrode leads. These leads can be placed to measure a single biopotential signal such as ECG, EEG, or EMG. Weighs ~12 g (7 cm³) and includes 25 cm long biopotential leads.

The Dual Rat Biopotential Telemeter measures the biopotential difference between each pair of electrode leads. The leads can be used to measure two biopotential signals such as ECG, EMG and/or EEG. Weighs ~12 g (7 cm³) and includes 25 cm long biopotential leads.

The Rat Pressure Telemeter measures high fidelity pressure using a solid-state Millar Mikro-Tip^TM sensor. Pressure is measured directly at the tip of the catheter (2Fr in diameter, 9 cm long (15 cm & 25 cm options available)) and the telemeter can be used to measure arterial, venous, ventricular or intracranial pressure (25 cm catheter required). The telemeter weighs approximately 12g.

The Rat Pressure Biopotential Telemeter combines measurement of high-fidelity pressure using a solid-state Millar Mikro-Tip^TM sensor with a single biopotential signal (e.g. ECG, EEG or EMG). Pressure is measured directly at the tip of the pressure catheter (2Fr in diameter, 9 cm long (15 cm & 25 cm options available)) and the telemeter can be used to measure arterial, venous, ventricular or intracranial pressure (25 cm catheter required). The biopotential signal measures the potential difference between the pair of 25 cm coiled electrode leads. The telemeter weighs approximately 12g.

The Rat Dual Pressure Telemeter measures two high-fidelity pressures using solid-state Millar Mikro-Tip^TM sensors. Pressure is measured directly at the tip of each pressure catheter (2Fr in diameter, 9 cm long (15 cm & 25 cm options available)) and the telemeter can be used to measure arterial, venous, ventricular and/or intracranial pressures (25 cm catheter option).

The Rat Sympathetic Nerve Activity (SNA) and Pressure Telemeter is the only commercially available telemetry device that allows concurrent measurement of SNA and pressure. the telemeter weighs approximately 12 g with a Millar solid state pressure sensor (2Fr in diameter, 9 cm long (15 cm & 25 cm options available)) and multi-stranded SNA lead wires (25 cm long). The telemeter samples the pressure and SNA signals at 2 kHz with an SNA input range of ±60 µV.

The Rat Tissue Oxygen Telemeter is an implantable potentiostat with a carbon paste electrode specifically configured for measuring tissue (e.g. brain, kidney) oxygen concentration in freely moving rats >175 g. The telemeter can be easily cleaned and sterilized for reuse after attachment of new electrodes. Ideal option for cohousing option in order to measure tissue oxygen measurement with other signals by placing two telemeters in one rat.
