Extend the life of your pH and ORP sensors by using the Sensorex pH electrode storage solution. When the sensor is not in use, place the sensor glass measurement area into the storage solution. The pH electrode storage solutions are supplied in pints (473 ml).

Refillable glass pH electrodes contain liquid electrolyte solution, which serves to close the electrical circuit in a pH electrode. The electrolyte solution must have electrical contact with the solution being measured. Contact is made via a semipermeable junction, which permits a consistent outflow of liquid electrolyte.  Over time, electrolyte is depleted and should be replaced. 3.5 M liquid KCl for Sensorex model pH3000 3.5 M liquid KCl/AgCl for Sensorex model pH1400

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 *Hach is a registered trademark of Danaher.

Refillable sensors can maintain accuracy for longer time periods. This sensor type requires re-filling with KCl solution when the liquid level is about 1” below the re-fill hole. To do this, slide the protective outer sleeve up to expose the filling hole and fill the electrode to the hole level with KCl (potassium chloride) solution.

The B125 ORP Calibration kit can be used for a simple calibration of both pH and ORP sensors. Use this kit for pH calibration, then convert the pH buffers into stable ORP buffers by saturating with quinhydrone. The B125 ORP calibration kit is a complete, ready-to-use package and can be used for up to 30 calibrations. Simple calibration of pH and ORP simultaneously Fast response time Mix and prepare the calibration buffers in seconds Instantly ready for use and ships with plastic beakers and stirring sticks One year shelf life guaranteed

Our TDS / Conductivity Calibration Standards are prepared to NIST (National Institute of Standards and Technology) primary solutions standards. Both Mixed Salts and Single Salt solutions are available. A NIST certificate is also available for a nominal charge. Solutions are supplied in quart bottles (946 ml) and are ready for immediate use. Both the TDS and the conductivity values are listed on the label. Shelf life is guaranteed for a year, and each solution is supplied with a MSDS sheet.

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
