  • Checktrode 1089E Electrode Tester

    This new design incorporates a microprocessor. A crystal-controlled 30 Hz. sine wave (not a square wave) is supplied to the electrode pair under test. Leads connect to the electrodes using the industry standard .060' safety jacks. The 1089e supplies simple 'pass-fail' LED indication for the contact impedance ranges of <5KOhm, <10 KOhm, <20 KOhm, <50 KOhm, and >50 KOhm. Simple, single switch operation, with automatic power down, further simplifies the use of this essential, 9V battery powered instrument. 1 year warranty.

  • Checktrode 1089MK3 Electrode Tester

    Supplies quick and easy evaluation of total contact impedance and offset voltage between two applied electrodes. The 1089 uses an AC excitation method which removes the effects of the polarization errors from the impedance reading. Leads with both the older .080' pin plugs as well as the newer .060' safety jacks are supported. The inclusion of a standard male snap allows electrode lead testing as well. A loaded battery test function is also provided. The 1089 is powered by a standard 9V battery and automatically shuts down after 3-6 minutes. 1 year warranty.

  • Checktrode 1089MK3ES Electrode Tester

    The 'ES' includes a switch and associated circuitry to select up to 22 separate electrode leads. This allows the 1089 ES to be used to rapidly and painlessly check applied electrode contact impedance of multiple electrode configurations such as Cranial EEG 'caps'. 1 year warranty.

  • Checktrode 1089NP Electrode Tester

    The Model 1089NP evolved from the 1089ES,and has a few important differences. Whereas the 1089ES is a general-purpose instrument, the Model 1089NP is intended for use with several specific electrode caps. These include the Brainmaster Discovery qEEG system cap, the NeuroPulse Systems qEEG cap, the Mistar Systems cap and any standard Electro Cap or Comby Cap used with other qEEG systems. For ease of use, Model 1089NP rotary selection switch positions are directly keyed to electrode site names for the listed caps. A two-position TEST switch permits the two reference electrodes supplied with these caps to be tested against each other. When good contact between them has been established, just flip the TEST switch to link the two reference electrodes, then check contact impedances of the remaining cap electrodes. 1 Year Warranty.
