AD131 – AD132 Professional Waterproof pH – ORP – Temperature Portable Meter with RS232 interface and GLP

Description

AD131 and AD132 are heavy – duty portable waterproof meters for pH, ORP (Oxidation Reduction Potential) and temperature measurements, designed to provide laboratory results and accuracy even under harsh industrial conditions.

Main features include:

  • 7 memorized buffers for pH calibration (pH1.68, 4.01, 6.86, 7.01, 9.18, 10.01 and 12.45)
  • Message on the LCD to make the calibration easy and accurate
  • pH readings with manual or automatic temperature compensation
  • Calibration time out alarm
  • Log – on – demand
  • HOLD feature to freeze stable reading on the LCD
  • GLP feature to view last calibration data for pH and relative mV
  • PC interface ( only for AD132 ) 
  • Connection to an external serial printer with the following specification ( only for AD132 ): At least 16 characters / line, baud rate 9600 and RS232 input
