The Labmart OCM21 Online Conductivity Controller is designed for continuous monitoring of water conductivity and total dissolved solids (TDS) in industrial and process applications. It offers a wide conductivity measurement range, selectable cell constant and temperature coefficient, adjustable TDS conversion factor, automatic temperature compensation, configurable high/low alarms, 4–20 mA output and RS485 communication.
The OCM21 supports 1–3 point calibration with automatic recognition of conductivity standards and is supplied with an online conductivity electrode and 5 m cable.
Product Overview
The Labmart OCM21 Online Conductivity Controller is an online conductivity monitoring instrument intended for applications where continuous measurement of electrical conductivity and total dissolved solids of water is required.
The controller provides multiple selectable conductivity measurement ranges extending from 0.01 µS/cm through 200.0 mS/cm, with measurement resolution selectable according to the operating range. It also provides TDS measurement, automatic temperature compensation and adjustable TDS conversion factors.
The OCM21 is designed with configurable process-monitoring functions including high/low limit alarms, a 4–20 mA analogue output and RS485 communication. A setup menu allows configuration of calibration points, alarm limits, hysteresis and output-related settings.
