Hygiena HYCAL-0000 LED Calibration Verification Kit for ATP Monitoring Systems

The LED Calibration Verification, CalCheck is a reusable, convenient LED device to quickly and reliably verify the calibration on your luminometer.

Though all Hygiena luminometers run a calibration self-check at startup, a robust quality control program will often require proof that your instrument is calibrated. CalCheck provides all-in-one, reusable positive and negative calibration verification, activated simply by the click of a button.

Trusted by Industry and Professionals
CalCheck has been cited in laboratory quality control guidelines and food safety monitoring studies for its reliability in verifying luminometer calibration. Independent reviews from food safety auditors and laboratory technicians consistently note its ease of use and accuracy in routine checks. Commonly used in food processing facilities, research labs, and QA departments, CalCheck helps maintain compliance with HACCP and other regulatory programs while providing peace of mind to operators. Users report that it reduces downtime and streamlines internal audits, making it a practical addition to any hygiene monitoring system.

Key Benefits

Confirm Calibration in Seconds Record Calibration History for Audits Powered by Standard Batteries

The LED Calibration Verification device is a compact tool used to quickly confirm that a luminometer is properly calibrated and functioning correctly. The device contains a stable LED light source that produces a known light signal, allowing users to verify that the instrument detects and reports expected values. This type of verification device is commonly used in food safety testing programs that rely on ATP luminometers to monitor sanitation and surface cleanliness in processing facilities. 

LED calibration verification units—such as the CalCheck device from Hygiena—provide both positive and negative calibration checks in a simple two-step procedure. By inserting the device into the luminometer and activating the LED signal, operators can confirm in less than a minute whether the instrument is measuring light accurately. Because the LED produces a stable and repeatable light output, it serves as a reliable reference standard for verifying instrument performance during routine quality control checks. 

These verification tools are widely used in laboratories and food processing environments as part of sanitation monitoring programs. Routine in-house verification helps demonstrate that measurement systems remain in control, supports compliance with audit and quality assurance requirements, and reduces the need for frequent manufacturer recalibration. Many devices operate on a small replaceable coin battery and can be reused for unlimited verification checks, making them a convenient addition to routine equipment maintenance procedures. 

Track Calibration History to Support Audits

In-house calibration checks confirm the Hygiena luminometer is working properly and demonstrate due diligence that a monitoring system is in control. CalCheck verifies your instrument’s calibration in-house as part of a quality control program and eliminates the need for manufacturer calibration checks, saving you hundreds of dollars each year.

Works with All Hygiena Luminometers

Whether you have a SystemSURETM Plus, EnSURE® or EnSURE® Touch, CalCheck is the perfect companion and an essential device to support your food safety SOP and conquer your food safety audits.

Powered by a Standard Battery

The CalCheck LED will turn red when the battery needs to be replaced. Simply replace the standard coin-size CR1025 lithium battery and you are good to go. No hassle… no fuss.

Confirm Calibration in Seconds
