THE DEVICE

The MultispeQ is a handheld, bluetooth or USB connected device which can measure reflectance, fluorescence, or absorbance at 6 different wavelengths. It has 2 detectors (visible light and infrared) and uses pulse modulation to eliminate any interference from ambient light. This means the sample does not have to be covered. It also contains additional sensors to measure temperature, relative humidity, CO2, and photosynthetically active radiation (PAR). Our target price for the MultispeQ is ~$100. Learn More

THE MOBILE APP

Photosynq mobile app is available on Google Play store.

The Device

The MultispeQ is a handheld, bluetooth or USB connected device which can measure reflectance, fluorescence, or absorbance at 6 different wavelengths. It has 2 detectors (visible light and infrared) and uses pulse modulation to eliminate any interference from ambient light. This means the sample does not have to be covered. It also contains additional sensors to measure temperature, relative humidity, CO2, and photosynthetically active radiation (PAR). Our target price for the MultispeQ is ~$100.

The MultispeQ can perform a wide array of protocols for measuring plant health, include pulse modulated PSII efficiency (Phi(II) and Fv/Fm), chlorophyll content, soil biological activity, soil active carbon, fluorescence transient, electrochemical shift (ECS), PSI efficiency, and others. The hardware (along with all software and data in PhotosynQ) is open source, so additional sensors can be added easily, like soil moisture or pressure.

In addition to protocols we have created for plant applications, users can create their own protocols. One could use the device as a general purpose colorimeter/spec capable of measuring turbidity or total suspended solids for water quality, jaundice or even blood oxygen content for medical applications, or fluorescing proteins in kinetics measurements for scientists.
