1. PAR (Quantum) Meter
The PAR Meters are accurate to ±5%. Cosine correction is accurate to ±3% at 45°, and ±7% at 80°.
Quantum Light Meters are calibrated to display PPFD. The meters display PPFD in the range 0-1999 µmol m-2 s-1.

2. LUX Meter
- Light sensor attached to 1.5 meter coaxial cable
- Rugged, waterproof case
- Low-battery indicator
The instrument is supplied with a light sensor connected by a fixed 1.5 m coaxial cable to allow measurements to be taken from a distance without any interference from the operator.
By simply pressing the RANGE key, users can switch among three ranges to choose the best resolution according to the environment being tested. The lux meter has a rugged and water-resistant body for frequent outdoor use.
The lux meter features a low battery indicator and automatic shut-off feature that turns the meter of after 7 minutes of non-use. Powered by a single 9V battery, this instrument guarantees about 200 hours of continuous operation.
- Range: 0 to 200,000 (lx, LUX) (0 to 3700 umol m-2 s-1 PAR)
- Resolution: interchangeable between 1, 10 and 100 lx
- Accuracy: ±6% of full scale
- Power Supply: 9V battery, approx. 200 hours lifespan
2. Q201 Quantum PAR Radiometer
The Irradian portable digital quantum radiometer model Q201 is a versatile, direct reading instrument designed specifically for measuring photosynthetic active radiation (PAR) over the spectral range 400 to 700nm, in units of µmol / m² / s (or alternatively in units of micro Einstein / m² / s ).
The operating range of 0 to 1999.9 µmol / m² / s makes the Q201 suitable for sunlight and controlled environment chamber measurements.
The radiometer comprises of a handheld display unit with battery, detector and integral amplifier, with interconnecting cable. The meter also includes a calibration certificate and carrying case for protection and transportation.
The Q201 PAR radiometer offers lower cost combined with an Irradian high accuracy PAR response, cosine corrected detector.
The Q201 may be used in applications such as Agriculture, Horticulture, Plant Growth studies, Biology and Liminology (with under water detectors).
3. Photosynthetic Photon Flux (PPF) Spectrometer
Edaphic Scientific’s range of spectrometers measure the quality of light in the spectral region between 400 and 700nm. The quality of light is critical for plant growth where plants need an abundance of radiation in the blue and red regions. Our spectrometers can be used to check LED in growth cabinets or artificial environments, or our spectrometers can be used to assess light quality in glasshouses, greenhouses or vinyl houses.
