Description
Conductivity meter P2-30-SK is an analog conductivity instrument with SK quick coupling for mixed-bed ion exchanger systems. It combines an analog display with an integrated pressure-resistant measuring electrode (c = 0,2) and an LED that indicates operating voltage. The meter is designed for direct mounting on the pure-water outlet of ion exchanger cartridges fitted with SK plug connection and matches pressure-resistant stainless-steel ion exchangers SG 2000-SK through SG 15000-SK from manufacturer Evoqua Water Technologies. Measuring range is 0,5–20 µS/cm. Supply voltage is 230 V, 50–60 Hz via a 1,4 m cable with Euro plug; power consumption is 2 W. Protection class is IP54, cable entry uses a bend-protection grommet, and dimensions with electrode are 138 mm height × 106 mm width × 62 mm depth. As accessory instrumentation for VE cartridges and full deionisation setups, the P2-30-SK provides continuous conductivity indication at the pure-water outlet for laboratory pure-water monitoring.

Questions about Conductivity meter P2-30-SK
What is this article?
Conductivity meter P2-30-SK is the article on this page. Luminix Health distributes Evoqua Water Technologies for laboratory use. It sits in Conductivity meters & cells, inside pH & electrochemistry, in Lab instruments.
A conductivity meter and its cell measure how well a solution carries current. The cell constant is the geometry that converts conductance to conductivity, and it is calibrated with a standard. Temperature compensation matters because conductivity rises with temperature.
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.
