Mission Statement
What do we do?
BWB+ISI offers an Elite series of industry proven pH and ORP sensors and electrodes based on Patented Technology pioneered in the late 1970s and early 1980s and perfected on a continuous basis.
How do we do it?
With hundreds of pH electrode and sensor manufacturers now globally, how is an individual or engineer to make
a selection for their application out of the thousands of choices? We have narrowed down this enormous number of varied brands and designs to 15 models that can easily be selected from the BWB+ISI brochure and ordered via our on-line store.
Whom do we do it for?
We cater to end-users, skid builders and municipal, commercial and educational institutions via a global network of BWB+ISI dealers.
What value do we bring?
Decades of design and application experience have gone into developing the BWB+ISI Elite Series. Our on-line store makes selecting and ordering the right product for your application easy.
Where are our products used?
Analog vs Digital Sensors and Electrodes
Analog Pros
• Original, Legacy Technology
• Compatible with a large installed base of transmitters
• Cross compatible between many manufacturers and brands of instruments with Pt100 temperature compensator
• Allows for both fixed cable and plug-in head designs
• More cost effective as compared to digital sensors
Analog Cons
• Does not have the features listed as “Digital Pros” opposite
• Can Not be used as replacements for digital sensors
Digital Pros
• No impedance problems, longer cable lengths possible
• No ground loop problems
• Plug and play with pre-calibrated sensors • Data and process information storage
Digital Cons
• Limited suppliers to choose from
• Most have proprietary protocols requiring single source of both transmitter and sensor
• Must buy sensor and separate cable which add costs
• Replacement electrode/sensor more expensive than analog
