Tipo de pantalla: digital Con luz de fondo o no: No Suministros de bricolaje: electricidad Descripción del Producto Un medidor de TDS (también conocido como bolígrafo de ppm, comprobador de nutrientes, varilla de TDS) es una herramienta digital económica y conveniente para verificar instantáneamente la calidad general del agua. TDS = sólidos disueltos totales, que es cualquier sal, metal o mineral presente en el agua. Con solo presionar un botón, el TDS puede indicarle el nivel general de pureza del agua, que se mostrará en la pantalla en ppm (partes por millón). Cuanto menor sea el nivel de TDS, más pura será el agua; 0 ppm es H2O puro. El TDS es ideal para verificar la calidad del agua del grifo o saber cuándo cambiar un filtro. (El medidor no realiza pruebas de contaminantes biológicos). El TDS es una gran herramienta para agua potable, filtración y purificación de agua, plata coloidal, hidroponía (para probar los nutrientes), acuarios, sistemas de ósmosis inversa/difusión, piscinas y spas, aplicaciones comerciales e industriales y más. El TDS es un modelo resistente que incluye un estuche protector de transporte. Este es el medidor de TDS portátil más popular del mundo para profesionales de la industria. ts Ideal para uso comercial Incluye un estuche de transporte con clip para cinturón Función de sujeción: guarda las mediciones para una lectura y registro convenientes Altamente eficiente y preciso debido a su tecnología avanzada de microprocesador Termómetro digital incorporado, Pantalla: Pantalla LCD grande y fácil de leer.
