The HI-Q123 is available inside an Explosion Proof Housing approved for Class I, II & III, Cenelec, EEx and NEMA 4, 7 & 9 for application requirements in the Petrochemical, Ordinance, Mining, Pharmaceutical, Semiconductor and Biomedical Industries. Also available in standard "Switchboard" panel mount and sanitary cases.

Some applications are for Serial Remote Display/Controller for PLC, SCADA, DCS or Stand Alone for up to 3 variables such as V/A/W, Pressure/Flow/Volume, Temperature/Humidity/Time, pH/ORP/Level and many more. Up to 3 signals are accepted and their mathematical product is displayed on the bargraph or digital or both simultaneously to give a trend and an instantaneous reading.

The Controller's display is backlit with an automatic tricolor backlight visible through the high temperature window. The HI-Q123 features 101 segment high contrast backlight bargraph with a 6 digit display with 4 alarm annunciators, RS232/422/485 I/O, analog (2) and relays (4) outputs, power inputs of 5, 8-32VDC or 90-265VAC and signal inputs for V/mADC and True RMS, TC, RTD, Strain-Gage, 4-20mA, OHMs, ORP, pH, Event, Time and Hz. The 18 bit ADC gives a stable 6 digit reading with a 0.0001% resolution. The powerful math functions, polynomials and X-Y tables are all configurable via the serial port or keypad.
