Conductometer / pH meter KTA-2
Conductometer / pH meter KTA-2 It is a representative of a new generation of multifunctional high-precision instruments with a touch control panel. Designed for measurements of pH, specific electrical conductivity (SEC), mass concentration of salt in terms of NaCl (salt content), mass concentration of dissolved salts (TDS) and oxidation-reduction potential (ORP) in liquid media with simultaneous temperature measurement. Distinctive features: color display with touch control panel and intuitive interface; ability to work with any type of combined electrodes for pH measurement (BNC connector); The conductivity meter does not require calibration, but calibration is included in settings functions and can be used to adjust coefficient (constant) of the conductometric sensor and during verification; the presence of the “Thermal compensation” option, which allows for measuring the electrical conductivity, adjusted to a user-specified temperature (in the range from 5 to 80 °C; by default - to 25 °C); to maintain high accuracy of measurements of the given UEP, a choice of thermal compensation option is available, taking into account the characteristics of the liquid being analyzed: for especially pure solutions; for weak electrolytes; for strong electrolytes; to measure small UEP values, use a two-electrode sensor DK-2 (Ø14 × 142 mm; weight with cable 70 g); to measure high SEP values, a patented five-electrode conductometric sensor DK-5 (Ø14 × 157 mm; weight with cable 60 g) is used; the sensors have a built-in temperature sensor; the electrodes in the sensors are made of stainless steel steel; the design of the sensors ensures convenient measurements and ease of cleaning; availability of an option for auto-detection of buffer solutions; measurement results are stored in an archive and available for viewing (memory for 149,000 measurement results); powered by any of the following methods: from the built-in battery / from the network / from a computer; continuous operation from the built-in battery for 13 hours; KTA-2 can be recharged using a wireless charger (included in the delivery package if approved at the purchase stage). Scope of delivery: Conductometer / pH meter KTA-2. Sensor DK-2, DK-5 or both sensors (depending on the selected configuration). Combined electrode for pH measurement (as agreed upon at the purchase stage). Thermal sensor. Charger with USB connector. USB-C connecting cable. Operation manual. Verification method. Sensor passport (depending on the selected configuration). Manba: https://www.nv-lab.ru/catalog_info.php?ID=9985
