These advanced laboratory meters with one or two input channels are ideal for testing critical water quality parameters.
- Single- or dual-input channel for pH, ORP, mV, temperature, conductivity, TDS, salinity, DO and ISE: For use with any IntelliCAL™ electrode
- Simple user interface that does not require manuals or training to operate
- Guided calibration and check standard routines reduce calibration errors while stabilisation alerts
- Internal USB ports simplify data transfer, peripherals and software updates, and connection to PCs printer and keyboards
- Fully GLP compliant communication and documentation
- Ultra-bright screen and large font size for easy to read results
The meters connect with smart probes (IntelliCAL™) that automatically recognise the testing parameter, calibration history, and method settings to minimise errors and set-up time. They are designed to withstand years of continuous lab use.
: Supplied with four batteries, universal power adapter, USB cable and electrode holder. IntelliCAL™ electrodes need to be ordered separately.
