The InsMark IS228 Benchtop Conductivity & Water Quality Meter is a high-performance laboratory instrument designed for precise and reliable measurement of key water quality parameters. It supports conductivity, resistivity, TDS, salinity, temperature, and conductivity ash, making it suitable for research laboratories, quality control labs, water treatment facilities, and industrial applications.
Equipped with a 5-inch color touch-screen LCD, the IS228 offers an intuitive user experience and automatic measuring range adjustment for enhanced accuracy. The meter features ±0.5% accuracy for conductivity-related parameters and ±0.1°C accuracy for temperature, ensuring dependable results in demanding environments.
The instrument includes GLP (Good Laboratory Practice) data management, allowing users to store up to 2000 data sets for traceability and documentation. With multiple temperature compensation modes (linear, non-linear, pure water, or compensation off), the IS228 adapts easily to different testing conditions.
Connectivity options such as USB, RS232, and optional printer support enable seamless data transfer and reporting. The meter is supplied with a tetracyclic conductivity electrode, electrode holder, protective cover, and calibration buffers, making it ready for immediate laboratory use.
