Description
SX725 portable pH/DO meter set delivers laboratory-quality measurement of pH and dissolved oxygen (DO) in general aqueous solutions. Compact design, IP57 dust and water protection and the included robust carrying case make it ideal for field deployment in demanding surroundings. The kit contains the 201T-S pH/temperature electrode with lithium glass membrane and ceramic junction for rapid, precise pH readings and automatic temperature compensation, plus the polarographic DO500 electrode that is ready after only 5 minutes of polarisation. Automatic temperature and salinity compensation together with manual barometric-pressure compensation support fast, accurate DO results; 90 % response is reached within 30 seconds, and three spare membrane caps plus refill electrolyte are supplied. From manufacturer APERA Instruments, the instrument offers 1- to 3-point pH calibration, digital filter technology and storage of 300 data sets. pH range is −2,00 to 19,99 with 0,1/0,01 resolution; DO covers 0 to 19,99 mg/L (ppm) and 0 to 200,0 %. Powered by two AA batteries, the complete set also includes pH 4,00, 7,00 and 10,01 calibration solutions (50 ml each), DO502 electrolyte, polishing paper, screwdriver and carrying case. Applications include water treatment, environmental monitoring, beverage production, aquaculture and aquarium control.

Questions about SX725 Portable pH/DO Meter Kit
What is this article?
SX725 Portable pH/DO Meter Kit is the article on this page. Luminix Health distributes APERA Instruments for laboratory use. It sits in Dissolved oxygen & multiparameter meters, inside pH & electrochemistry, in Lab instruments.
A dissolved-oxygen meter reads oxygen in a liquid, optically or with a Clark cell. A multiparameter meter adds pH, conductivity or both on one instrument. The sensor cap or the membrane is the consumable. A reading in air and a reading in water are different calibrations.
A pH meter is a voltmeter on a glass electrode. The voltage tracks hydrogen-ion activity, and the electrode is converted to pH only after it is adjusted with buffers of known value. Conductivity measures how well a solution carries a current, which for dilute salts tracks concentration. Dissolved oxygen and titration are further electrodes on the same idea: a sensor, a standard, and a reading that is only as fresh as the calibration. Buffer values and chemical identity sit on PubChem. Accreditation of the calibration laboratory is the field of BELAC and EURAMET.
