ECscan30 conductivity tester is a multi-parameter meter which used to measures the conductivity and TDS of liquids.   Features: Standard platinum sensor provides fast and reliable measurements. Up to 3 points calibration allows user to uses customized calibration     solutions. Adjustable TDS conversion factors. Automatic Temperature Compensation ensures highly accurate     measurements over the entire range. Hold function freezes the current displayed value for easy viewing     and recording. Setup menu lets user customize calibration points, temperature unit,     automatic or manual hold function to meet personal preferences. Reset feature allows user to resume all of the default settings. Auto-power off feature helps you effectively conserve battery life. Replaceable electrode reduces maintenance and replacement cost. Waterproof feature to ensures complete protection in harsh     environments.

Bante520 is aneconomical and easy-use conductivity meter for field or laboratory applications. The meter with auto-ranging feature that can quickly measures the electrical conductivity of liquids, accuracy up to ±0.5% full scale. Features: Single point push-button calibration allows user to uses customized     calibration solution. Adjustable cell constants and temperature coefficients. Automatic Temperature Compensation ensures highly accurate     measurements over the entire range. Manual temperature calibration provides accurate measured value. Selectable either temperature units between degrees Celsius (°C)     and degrees Fahrenheit (°F). Hold function freezes the current displayed value for easy viewing     and recording. Help message as a operational guide to helps you understand how     to use meter. Setup menu lets user customize temperature units, date and time to     meet measurement requirements.
