HI4000-47 is a set of pH 4 and pH 7 buffer packets (includes 10 packets of each buffer). These buffer packets contain chloride ions to allow an inner electrode check of the ammonia and carbon dioxide ion selective electrodes.
The ammonia and carbon dioxide sensors are both gas sensing, combination ion selective electrodes (ISEs) that contain an internal glass pH element to determine ammonia and carbon dioxide concentrations, respectively. An inner electrode check with the HI4000-47 buffers ensures the pH element is in working condition, permitting accurate ISE measurements.
