    Physiological recordings can be easily contaminated by noise and interference. In many cases, high electrode contact impedance is a big part of the problem. Noise often appears as 50 or 60 Hz "hum" from surrounding AC-powered electrical devices or as erratic spikes due to any motion of the lead wires. In virtually every case, these troublesome artifacts can be mitigated or completely eliminated by reducing contact impedance at the skin/electrode interface. UFI's Checktrode™ applied electrode contact impedance testers are designed to help accomplish this task.

    Model 1089ES Checktrode with Lead Selector

    The "ES" includes a switch and associated circuitry to select up to 22 separate electrode leads. This allows the 1089ES to be used to check applied electrode contact impedance of multiple electrode configurations such as Cranial EEG "caps" -- rapidly and painlessly. Price includes interfacing to the connector of your choice for most connectors. Please indicate your required connection type if other than Standard caps.
