SD7000CD & SD7000CD-ORP
PRODUCT SPECIFICATION SHEET
DIRECT REPLACEMENT 5-WIRE DIFFERENTIAL pH AND ORP SENSORS
Employs differential measurement technique
Superior accuracy through elimination of ground loops
Buffered reference cell solution resists contamination
Direct fit replacements for Hach®/GLI differential sensors
Direct fit replacements for Water Analytics® models
Two year limited warranty
Differential sensors have longer working lifetimes
The differential design employs two glass electrodes, which
record pH or ORP measurements differentially with respect
to a third metal electrode. The reference cell of a differential
sensor is actually a measuring electrode in a concentrated pH
7.0 buffer solution rather than a traditional silver/silver chloride
reference. This type of reference cell resists contamination by
the sample, improving measurement accuracy and extending
sensor lifetime.
RECOMMENDED APPLICATIONS:
• Wastewater Treatment
• Drinking Water Treatment
• Odor Scrubbers
• Food Processing
• Metal Finishing
• Pulp and Paper
• Chemical Processing

Save time and money with quick and easy maintenance
With differential technology, you won’t have to replace the
entire sensor after just a few months. Simply replace the salt
bridge and refill the reference solution to keep your electrode
working longer.
An accurate and reliable sensor that works with your system
The differential design provides unsurpassed accuracy by
virtually eliminating ground loops. Automatic temperature
compensation ensures measurement accuracy in environments
with rapid temperature changes. Durable Ryton® PPS body
construction for extensive chemical compatibility.
