custom skus need to go here
It is a reusable positive and negative calibration device that allows you to verify the verification in two easy steps that only take seconds. Tracking your calibration history supports your quality process audits, the verification demonstrates due diligence during audits and proves that the luminometer is working properly.
The CalCheck has been designed to be directly used by the users and therefore eliminates the need for calibration checks by the manufacturer. The LED on the top of the device used a standard CR1025 battery and will turn red when the battery needs to be changed.
