FIELD EQUIPMENT / OPTICAL, ELECTROCHEMICAL & ANALYZER SYSTEMS
Our calibration service covers more than the displayed value. Sensor condition, temperature compensation, wiring, configuration, analyzer response, and the surrounding application are evaluated together—on site or through our mail-in lab.
Optical & electrochemical sensors
Calibration, inspection, cleaning, membrane or cap review, and response checks for portable or fixed optical and electrochemical sensors.
Analyzers & transmitters
Calibration and verification of configuration, temperature compensation, signal output, alarm behavior, and analyzer response.
Complete measurement loop
Complete-loop calibration can include the sensor, cable, transmitter, output, control-system indication, and relevant process conditions.
Dissolved oxygen sensors can lose response through fouling, membrane wear, cap aging, chemical exposure, cable damage, or configuration changes. Our technicians evaluate sensor health, calibrate the measurement system, document results, and recommend repair or replacement when needed.
On-site and mail-in calibration options
We can perform dissolved oxygen calibration at your facility or through our mail-in lab when the instrument and application allow, with clear documentation and practical next-step recommendations.
01
Inspect the probe, cap or membrane, cable, and installation conditions.
02
Clean the sensing surface and evaluate response, stability, and temperature behavior.
03
Verify calibration and analyzer response using the appropriate procedure and reference method.
04
Document results and provide a clear recommendation for service, repair, or replacement.
We provide on-site and mail-in lab calibration for dissolved oxygen systems used across municipal, environmental, aquaculture, and industrial operations.
Wastewater & aeration
Calibration for aeration basins, biological treatment, and process systems where sensor response and fouling affect control decisions.
Aquaculture & environmental monitoring
Calibration for portable field instruments and fixed monitoring systems used to track habitat and water quality.
Industrial water & process systems
Calibration for oxygen measurement in water, treatment, and process applications where dependable readings support quality and consistency.
