Advanced spectrometer system for precise light measurement in horticulture.
The Avantes HortiSpec+ Spectrometer System is meticulously engineered for accurately measuring light intensity and spectral distribution in the visible and NIR range, specifically within greenhouse environments. This system is crucial for optimizing plant growth and photosynthesis, which are heavily dependent on light intensity and its spectral composition.
Equipped with the NR Lite2 Net Radiometer probe, the HortiSpec+ facilitates the measurement of net radiation, which is the balance of incoming and outgoing radiation in outdoor settings. The unique design of the NR Lite2 features a double-sided detector with black conical absorbers that have an anti-stick, weather-resistant protective coating, eliminating the need for fragile plastic domes and ensuring low-maintenance operation.
The spectrometer component, AvaSpec – 2048, includes a CCD linear array with 2048 pixels, a Grating VA, and covers a wavelength range of 300 to 1100 nm. It features a 200 µm slit with a detector collection lens and an order sorting coating for enhanced precision. Data communication is facilitated via USB 2.0 at 480 mbps, and the system includes a diffusor aperture with a diameter of 3.9 mm.
The accompanying HortiSpec Irradiance software enables measurement in units of photon flux (µmol/s.m²) and provides parameters such as Lux, PAR, and spectral components like Blue, Yellow/Green, Red, and Far Red. The specifications of the NR Lite2 include a spectral range of 0.2 to 100 µm, a sensitivity of 10 µV/W/m², a response time of less than 20 seconds, and an operational temperature range of -30°C to +70°C.
Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.
We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.
We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.
With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.
Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.
Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.
Two to six weeks, depending on refurbishment scope and whether calibration is included.
We ship to 38 countries. Crating and customs handling are quoted with the instrument.
Tell us what you need and a scientist finds it for you, usually within the hour.
