Laboratory Conductivity Meters: HZPD-T503 & HZPD-T503F
Professional Laboratory Conductivity Meters: HZPD-T503 & HZPD-T503FProduct Overview
The HZPD-T Series Professional Conductivity Meters are elite-tier laboratory analytical instruments designed for high-precision water quality testing. Featuring a 5.0-inch color touch-screen, these meters provide a seamless user experience while delivering 0.5-grade accuracy, significantly outperforming standard 1.0-grade instruments.
Whether you are monitoring the purity of ultra-pure water, measuring salinity in desalination plants, or conducting conductivity ash analysis for the sugar industry, the HZPD series offers a robust solution. The inclusion of a standard 4-ring electrode ensures reduced polarization and maintains extreme accuracy even in hypersaline solutions.
Key Features

FAQs
What sets the HZPD series apart from standard conductivity meters?
The HZPD series offers 0.5-grade accuracy, which is higher and more precise than the standard 1.0-grade meters typically found in laboratories.
Which model is suitable for the sugar industry?
The HZPD-T503F is specifically designed for the sugar industry as it includes a built-in measuring method for conductivity ash.
How many standard solutions are pre-set for calibration?
Both models feature 10 kinds of pre-set international standard solutions and also support customized solutions.
What is the benefit of a 4-ring electrode?
The 4-ring electrode reduces polarization effects, ensuring high accuracy even when testing hypersaline solutions.
Can I measure ultra-pure water with these instruments?
Yes. The HZPD-T503F model specifically includes a "Pure-water" temperature compensation mode to ensure accurate readings for high-purity water.
Are these meters GLP compliant?
Yes, both models feature databases (up to 2,000 groups for T503F) that are auditable, trackable, and manageable to conform to GLP requirements.
What parameters are displayed on the screen?
The 5.0-inch color touch-screen can display conductivity, resistivity, TDS, salinity, and temperature.
Can I export data for reporting?
Yes, both units come standard with RS232 and USB outputs, with an optional printer available for direct reporting.
What are the temperature compensation options?
The meters offer linear (0.0~0.1/°C), non-linear, and off modes. The T503F adds a dedicated pure-water mode.
What is the measurement range for salinity?
The salinity range is 0.000 to 87.0 psu, which is approximately 0.00% to 15.00%.
How many endpoint modes are available?
There are three selectable endpoint modes: Auto, Manual, and Time.
What standard solutions are included with the package?
The standard solutions provided are 146.5 µS/cm, 1408 µS/cm, 12.85 mS/cm, and 111.3 mS/cm.
