Probes and sensors
This section of the catalog presents a wide selection of Hach Lange Intellical probes and electrodes for the most demanding laboratory and field tasks in the following parameters: pH, dissolved oxygen, BOD, conductivity, TDS, ORP, ammonia, ammonium, chloride, fluoride, nitrate and sodium. All Intellical probes are automatically recognized by the HQ / HQD series meters and retain their calibration data, eliminating the need to recalibrate when switching between meters. The Red Rod pH electrodes provide exceptional performance and response times for a wide variety of sample types in the laboratory. The rugged outdoor sensors are housed in a stainless steel housing and, thanks to digital technology, can be used with cables up to 30 meters. In addition to sensors and electrodes, this section contains solutions for sensor maintenance, conductivity standards and pH buffers.
