CaliQ Features

What is CaliQ?

CaliQ is a compact, inexpensive instrument that allows you to self-calibrate the MultispeQ instrument.

CaliQ makes it much easier to update to the latest firmware and also allows for custom calibration procedures.


One CaliQ device can calibrate multiple MultispeQ devices.

CaliQ calibrates the PAR light sensor and all PAR-emitting LEDs*.

CaliQ comes pre-calibrated by PhotosynQ and should be accurate for several months.CaliQ can be re-calibrated by PhotosynQ or with appropriate instruments by yourself.


This is particularly useful if you are conducting projects with multiple MultispeQs to ensure unbiased, accurate measurements.

No need to send ship MultispeQ devices!The new MultispeQ firmware will keep track of when devices are re-calibrated and alert you when calibration is needed.

Firmware support

The kit also includes updated calibration cards and methods for calibrating absorbance changes, SPAD and leaf thickness.

CaliQ makes updating the firmware easy because it incorporates the latest calibration technique and settings.


Future updates of the desktop app will provide information on when recalibration may be needed. This will keep your data accurate and reproducible.
