    Chemical processing, industrial water and wastewater applications can be challenging environments for a pH sensor. Chemicals from the process mix with the reference electrolyte solution, changing the chemistry and leading to erratic readings. Fortunately, our differential pH and ORP sensors feature buffered reference electrolyte (SDS-7050), which can be replaced or refilled when needed. Also compatible with other brands, including Hach* and Water Analytics*. Contains 500mL.
    • Internal fill solution for SD7000, SD7420, and SD7500 sensors
    • Compatible with popular Hach & Water Analytics 5-wire differential pH & ORP models
    • We stand behind all our products with the Sensorex Guarantee and one year warranty

  • ph simulator
    pH and ORP measurement loops can be difficult to troubleshoot unless you have the right tools. Our CAL-C110 simulator mimics the signal of a perfect pH or ORP sensor. No need to throw away good sensors when the issue may be the interconnection cables or pH/ORP instrument. The simulator costs less than most pH or ORP sensors. It can easily pay for itself the very first time you consider disposing of a perfectly good sensor. Allows the user to identify the sensor, cable, meter, preamplifier, or controller as the cause of the problem.
    • An essential tool for troubleshooting pH and ORP systems
    • Compatible with most pH and ORP systems using BNC connectors
    • Simulate high impedance loads
    • Instantly ready for use and includes 9V battery
    • One year limited warranty
