The document introduces a combination rugged flat surface pH electrode from Extech Instruments Corporation, which features flat surface technology for quick on-the-spot pH measurements combined with autoranging high accuracy conductivity cell. The product measures 5 parameters including conductivity, TDS, salinity, pH, and temperature using one electrode. It has various features such as adjustable conductivity to TDS ratio, RENEW feature, auto power off, and low battery indicator. The product is waterproof to IP57 and includes electrode, protective sensor cap, sample cup with cap, and neckstrap. The EC510 kit also includes conductivity calibration standards and pH buffer pouches.
The Extech Instruments EC500 is a rugged, waterproof ExStik II pH/Conductivity Meter designed for quick on-the-spot measurements. It utilizes a combination flat surface pH electrode and conductivity cell to measure five parameters: Conductivity, TDS, Salinity, pH, and Temperature using a single electrode. The device features autoranging high accuracy, an analog bargraph for trend indication, and memory storage for up to 25 labeled readings.
