Handy Quantam Meter Basic BQM-01
Quantum Meter Cable Probe QMSS
The Basic Quantum Meter is used to determine
the amount of light that plants use.
It accurately estimates radiation in the
400 - 700nm range, which is the specific
range of light used by plants.
Easy to use:
You only --just turn it on, hold it at eye level
(with the sensor surface on top horizontal) and
read the values.
The sensor is cosine corrected for operation in
sunny or cloudy weather and at high noon or when
the sun is lower in the sky.
The Basic Quantum Meter reads solar radiation of
0 - 1999 µmol m2 s1 (0 - 10,000 foot candles).
It has a standard operating range of 32 - 122°F
with less than 80% relative humidity from 32 - 86°F
and less than 70% relative humidity from 86 - 122°F.
It runs on one 9V battery (included).
Features:
* Determines the amount of light plants use
* Has a domed diffusion disk and head for improved
self-cleaning characteristics and long-term stability
* Innovative blue lens improves the accuracy of
sensor and meter
* Pigments in the lens filter incoming light
