Electronic Stimulators


CRS-ST

The stimulator family of Experimetria Ltd. Looks back to an almost 20 years history. During these years the basic design changed three times and continuous further development of the system’s technical parts make these instruments the most handy and useful tools for pharmacological, physiological and neurophysiological studies.
CRS-ST is a microprocessor controlled modular square impulse stimulator.

The stimulator is made up of three major units:
  1. the microprocessor controlling unit (MCU unit)
  2. the analog end-amplifier unit
  3. accumulator charger for accumulator isolated unit

The analogous end-amplifiers are available:
  • with built-in opto-separator at the power of 100V/100 mA (type: PTS)
  • with built-in isolator at the power of 100V/100 mA (type ISO)
  • with built in accumulator isolation at the power of 50V/50 mA (type: AISO)

The number of end-amplifiers that may be connected to the MCU unit may range between one and eight modules of any type.
  • intelligent error messages
  • last programmed train is saved
  • unique real current isolator end amplifier unit- absolutely ground free
  • accumulator isolated end-amplifier unit, with built-in recharger
  • stimulation is up to 100V or 100mA
  • current and voltage generator is built together in the end-amplifiers
  • analogue amplitude adjustment between stimulator ranges
  • stand alone programming unit (MCU), which can drive max. eight end-amplifiers
  • signal indicator LED, continuously showing processing train
  • switches for easy polarity changes
  • positive and negative squares in the same train
