The AR20 meter is a research-grade pH meter capable of a variety of functions including automatic temperature compensation, conductivity, and can accept a newer type of electrode called the ion selective field effect transistor (ISFET). The touch screen panel provides access to all operating functions, as well as help screens to assist in operation. System features include:  pH Mode:
  • Range: -2 to +20pH
  • Resolution: 0.1, 0.01, 0.001pH
  • Relative accuracy: ±0.002pH
mV Mode:
  • Range: 0 to ±1800mV, absolute or relative
  • Resolution: 0.1mV
  • Relative accuracy: ±0.1mV
Temperature Mode:
  • Range: -5 to + 105C (23 to 221 F)
  • Resolution: 0.1C
  • Relative accuracy: ±0.2C
