HI 504910 can acquire and transmit pH, ORP and °C measurements in a digital format to theHI 504 controller, or a industrial computer workstation. The digital link allows the user to send addi- tional information, regarding the pH, ORP and industrial temperature probes. Moreover, this transmitteris provided with the sensor check feature for pH and ORP electrodes, and can be connected toa Pt100 or Pt1000 temperature sensor manufacturer (with automatic recognition and damage test).The general setting and measurement parameters of the instrument can be easily set by theuser independently for pH and ORP configurations. The pH range can be calibrated through anormal 2-point procedure or through the innovative one-point system using HI 504920 (see following page). The temperature compensation mode can be automatic or manual (automati-cally selected when a temperature input error occurs). The transmitter can store up to 6000samples, pH/°C or ORP, complete with information about last calibration data (date and time, pH offset and slope, number and values of the used buffers). All stored data can be downloaded through the RS485 communication port using ourHI 92500 software.
