GL900-Series High-speed isolated multifunction logger (midi Logger)

Easy-to-use upright high-speed isolated multifunction logger.

An easy-to-use upright device enabling isolated 8-channel multifunction input, the GL900 is capable of performing high-speed simultaneous measurements of voltage, temperature, and various other phenomena.

	Voltage ±20mV to ±500V
	Temperature Thermocouples: K, J, E, T, R, S, B, N, W
	Humidity 0 to 100% (the B-530 option is required)
	Pulse 4 channels Count, Inst., Rpm
	Logic 4 channels ‡ Select either Pulse or Logic

*) The input signal needs to be not exceeding the specified voltage at any time.
The component in the amplifire of the unit may have the damage by over voltage.
Please check the details of over voltage in the specification sheet (Maximum input voltage or Withstand voltage seccion) or the caution label attached on the unit.
