Controllers and Transmitters

Color coded red, one pint (473mL) 4.01 pH Value. Buffer is NIST traceable and accurate to within ± 0.01 pH units at 25°C, and remain stable over long periods of time. Standard packaging is shown. As with all buffers, these solutions are temperature sensitive. For accurate calibration, heat or cool your buffer solution to 25°C before using. If this is not convenient, compensate for the thermal errors associated with these buffers.

Users installing into large tanks, large process lines and scrubber lines will appreciate this flat surface self cleaning pH sensor for use with our S675 hot tap (aka wet tap or insertion) assembly. The sensor features flat surface, self-cleaning pH glass for extended maintenance cycles. Protective feet protect against breakage against ball valve or side walls. A unique feature of this sensor is mounting orientation. It can be mounted in any direction whereas most pH sensor should be mounted 5 degrees above the horizontal plane. With the quick disconnect BNC, sensors can be changed in seconds should replacement be required. Designed for use with our S675 Assembly and a BV-1 Ball Valve for a complete hot tap pH measurement solution.
