pH AND mV SIMULATOR HD9609, Merk : DeltaOhm

GENERAL CHARACTERISTICS The simulator HD 9609 is a portable instrument for checking and calibrating pH and mV measuring instruments. The characteristics of this instrument satisfy any checking and calibrating requirements for both portable and panel-mounted instruments; it may be used in laboratories, in industry or for checks in the fi eld.Despite its many functions, the instrument is simple to use: a large display, with dual indication, and a series of symbols allow it to be used even by unskilled personnel. The HD9609 sends to output in channel A the simulation of signals of an electrode for measuring pH, ORP, ISFET, in the range: • 0 to 14 pH, with resolution 0.10 pH; • ±1999 mV, with resolution 1 mV. The user may choose between two output impedance values: • 100 K©, low impedance; • 1 G©, high impedance. The simulation of the electrode compensation temperature is manually programmed in the range from -20°C to +150°C, while the temperature is measured in degrees Celsius or Fahrenheit.The pH simulation values may be manually set as desired, in steps of 0.1 or 1 pH. The mV simulation values may be manually set as desired, in steps of 1 or 10 mV.The HD9609 is fed with an ordinary 9Vdc alkaline battery.The electronics are housed in a sturdy ABS case with ergonomic lines.In designing and making the instrument, each detail has been assessed and selected in order to provide an instrument with high performance and excellent long-term measurement stability.On request, the instrument may be certifi ed by a SIT centre or byanother centre recognized by the WECC.
