Product Description
The Hanna HI943500 Conductivity Analog Controller is engineered for demanding industrial and laboratory process control, providing direct input from a potentiometric probe (HI7638) without requiring a separate signal transmitter. Measuring conductivity across several selectable ranges, including 0.0 to 199.9 µS/cm, this device is suited for applications such as water treatment, manufacturing, environmental laboratories, and quality control in process industries.
With an isolated analog output signal (4-20 mA), the HI943500 ensures smooth integration with data loggers, recorders, or remote control systems. Manual two-point conductivity calibration using offset and slope trimmers, coupled with automatic temperature compensation (0 to 60°C), maximize measurement accuracy. A large, backlit LCD delivers clear visibility even in low-light industrial environments.
- Direct potentiometric probe input enables reliable, real-time conductivity monitoring at the source.
- Automatic temperature compensation guarantees stable, accurate readings over a wide operating range.
- Flame retardant ABS body with splash-proof transparent front cover withstands industrial and lab conditions.
- Multiple model options offer a variety of measurement ranges (e.g., HI943500A: 0.0–199.9 mS/cm, HI943500B: 0.00–19.99 mS/cm, HI943500C: 0–1999 µS/cm, HI943500D: 0.0–199.9 µS/cm).
- Membrane keypad and standard DIN panel cutout (141 x 69 mm) enable simple installation and operation.
- Auto-diagnostics and robust construction improve long-term reliability for continuous use.
- Operation temperature: -10 to 50°C; relative humidity up to 95%.
This controller is an industry standard for processes in water treatment plants, industrial manufacturing, chemical processing, and laboratory environments. Ships with a detailed user manual. Suitable for connection to HI7638 or compatible potentiometric probes (not included). Power supply: 115 or 230 VAC ±10%, 50/60 Hz. Approximate unit weight: 1 kg.
