Bristol Instruments Develops Programmable Universal Panel Meters

December 2, 2020

Bristol Instruments has developed a universal panel meter series that is based on a single chip microcontroller with a fast 24-bit A/D convertor, which which ensures high accuracy, stability and easy operation of the instrument. Programmable for 8 different mathematical functions, including DC, Process Monitor, RTD, T/C, DU, Ni, CU and resistance, the OM 402UNI Series universal panel meter is designed for maximum efficiency and user comfort while maintaining their favourable price.

The OM 402UNI Series can be used as voltmeters, ammeters, process monitors, ohmmeters, temperature instruments and display units. By further options of input modules it is feasible to measure larger ranges of DC voltage and current or increase the number of inputs up to 4 (applies for PM). 

The OM 402UNI Series meters are available with 0.8 or 0.5 inch tall 3-color LED displays. 


  • 5 Year Warranty
  • 3-Color display version
  • Relays, data output analog output (options)
  • 1/8 DIN size
  • Multifunction input: DC, Process Monitor, RTD, T/C, DU, Ni, CU and resistance
  • Mathematical functions including peak, tare, linearization and digital filters
  • DC Voltmeter and ammeter, ohmmeter, T/C & RTD thermometer
  • Display unit for linear potentiometers
  • Excitation option
