Which Input Module do I order for my FLXA21/202 analyzer?
The SC25F is a digital SMART pH sensor in a 12 mm design that includes an integral temperature element and a Liquid earth electrode.
The FLEXA™ series analyzers are used for continuous on-line measurements in industrial installations. With an option for single or dual sensor measurement, they are the most flexible two-wire analyzer available.
All-In-One pH and ORP digital SMART sensor that keeps the motto "Simple is best" while combing the sensor with built-in intelligence and direct digital communication.
The FU24F is a digital SMART pH/ORP sensor made with a chemical resistant PPS 40GF body for harsh pH applications.
Liquid analyzers are used for monitoring process chemistry including water quality, providing process optimization and control.
pH and ORP meters, analyzers and transmitters are used for continuous process monitoring of pH and ORP to ensure water/product quality, monitor effluent discharge, batch neutralization, pulp stock, scrubbers, cooling towers, chemical, water/wastewater treatment and many other applications.
pH electrodes and sensors are the sensing portions of a pH measurement. Various installation options including retractable, flow thru, immersion, and direct insertion. Proper pH electrode/sensor selection is critical for optimal measurement results.
Process analyzers are used to determine the chemical composition or physical properties of substances involved in industrial processes.
Digital or SMART sensors maintain specific measurement and calibration data on an integrated chip along that is an integral part of the sensor. This data can be exchanged between the sensor and either a process transmitter or a laboratory PC using a data management software, like the SPS24.
