HACH 9500.99.00604 Polymetron 9500 Controller 1 Channel Ultrapure Conductivity

1. Overview of the HACH 9500.99.00604

The HACH 9500.99.00604 is a Polymetron 9500 single-channel conductivity controller designed specifically for ultrapure water. It brings laboratory-grade precision to the field—with ±0.1% measurement accuracy and 0.001 μS/cm resolution. When paired with an 8310 electrode, it reliably captures every fluctuation in ultrapure water purity at the extreme 18.2 MΩ·cm. A 5.7-inch graphical LCD with LED backlight clearly displays real-time curves, electrode status, and temperature compensation. Its NEMA 4X/IP66 enclosure and wide operating temperature range of -20°C to +60°C ensure long-term online operation in demineralized water in power plants and UPW workshops in semiconductor factories, without risk of corrosion, condensation, or dust.

2. Core Features:

• Model: 9500.99.00604 (Polymetron 9500 Single-Channel Ultrapure Water Conductivity Controller)
• Measuring Range: 0.000 – 9.999 μS/cm (Autoranging up to 1000 mS/cm)
• Accuracy and Resolution: ±0.1 % F.S.; 0.001 μS/cm (@25°C)
• Display: 5.7" graphical LCD, 240 × 160 pixels, LED backlight, simultaneously displays real-time value, temperature, and electrode status
• Power Supply: 100 – 240 V AC, 50/60 Hz; 24 V DC version available
• Analog Output: Two isolated 0/4–20 mA outputs, load ≤ 550 Ω, accuracy ±0.1 % F.S. at 25°C, ±0.5 % F.S. over the entire temperature range
• Relays: 4-way SPDT (Form C), contacts 250 V AC / 5 A, configurable for alarm, timer, control, and system fault
• Communications (optional): Modbus RS232/RS485, Profibus-DP, HART 7.2
• Environmental: -20…+60°C, 0–95% RH (non-condensing); Enclosure: NEMA 4X / IP66
• Dimensions/Weight: 144 × 144 × 181 mm; 1.7 kg

Installation is simple: plug in the 8310 electrode and connect to a 100–240 VAC power supply. The controller instantly outputs two isolated 4–20 mA outputs and four SPDT relays for easy integration into a DCS, PLC, or SCADA system. Built-in bilinear, PID, and time-proportional control algorithms automate regeneration control for both cation and mixed beds. Dual password protection and a calibration log eliminate the need for additional paper records for FDA and GMP audits. Optional Modbus RS485, Profibus-DP, or HART 7.2 communication cards deliver real-time conductivity, temperature, and alarm information to the plant monitoring platform within ten minutes.
