9131C Waltron compact sodium analyzer
Waltron 9131C compact sodium analyzer for online dissolved-sodium measurement in ultrapure water, with touchscreen interface, internal temperature compensation and datalogger.
9131C compact sodium analyzer
Waltron 9131C Sodium Analyzer combines an ultra-compact design with uncompromising dissolved-sodium analysis in ultrapure water. The official page positions it for make-up water, condensate, boiler feedwater and steam applications, with low total cost of ownership.
The instrument includes a color touchscreen interface, internal temperature compensation, menu-assisted manual calibration, internal USB datalogger and easy access to replacement electrodes and KCl reference solution. It can be used with ammonium hydroxide or DIPA buffers.
The 9131C provides a displayed range from 0.01 ppb to 10 ppm and an analysis range from 0.10 ppb to 10 ppm, with two isolated 4-20 mA outputs, RS-232/RS-485 MODBUS RTU communications and three configurable alarm contacts. Its compact format supports panel or wall mounting.
