9035 Waltron sodium analyzer
Waltron 9035 sodium analyzer for online sodium monitoring in ultrapure water, with touchscreen interface, automatic calibration and internal datalogger.
9035 sodium analyzer
Waltron 9035 Sodium Analyzer is an online analyzer for sodium measurement in ultrapure-water applications. The official page positions it for common boiler-system measuring points such as make-up water, condensate, boiler feedwater and saturated or main steam.
The instrument includes a color touchscreen interface, true automatic single-point or two-point calibration, grab-sample capability, optional low-flow alarm and quick-connect electrodes. Calibration standards and electrode refill can last up to three months, reducing routine maintenance.
The 9035 covers a wide 0.1 ppb to 10 ppm range, with isolated 4-20 mA outputs, RS-232/RS-485 MODBUS RTU communications, internal datalogger and automatic logging of alarms and calibration results. Its IP65/NEMA 4X stainless-steel enclosure is designed for industrial service.
