Humidity and Air Measurement
Digital Thermohygrometer
Seedburo offers a durable, low-cost humidity and temperature monitor with selectable °F/°C scale. Ideal for lab, office, greenhouse, seed storage room and many other applications. The instrument is encased in corrosion resistant plastic hou
Humidity and Temperature Guides
Seedburo offers two durable, wall mount guides for determining relative humidity and temperature. The No. 444 reads relative humidity only from 0 to 100% on a 3¾" diameter dial with black numerals in a silver chromium case. Our No. 444T rea
Hygrothermograph
The Seedburo Hygrothermograph can be used for indoor or (sheltered) outdoor use. The unit provides a permanent record of temperature and relative humidity changes over a 1-day or 7-day period (and 32-day for No. 3725Q) and measures in °F or
Laqua Potassium K* Meter
LAQUA K* POTASSIUM SENSOR
Laqua Twin EC Meter
The Laqua Twin EC Meter offered by Seedburo measures the conductivity of soluble salts on plant growth. Conductivity (or EC) is the measure of total dissolved salts in a solution, the factor that influences a plant's ability to absorb water
Mini-Drum Hygrothermograph
Seedburo also offers an economical mini-drum version of the hygrothermograph. This unit offers a permanent record of temperature and relative humidity changes over a 7-day period (only). The instrument employs a quartz-controlled drive mech
Paperless Humidity and Temperature Chart Recorder
Ideal for monitoring controlled environments such as grain labs, storage, freezers, and other critical areas. Instrument can be either wall or desk-mounted for versatile, easy monitoring. Detachable humidity/temperature probe does not requi
Quantum Light Meter
Quantum sensors measure light energy at the specific wavelengths plants actually use for photosynthesis. Research indicates that older lux and foot-candle meters could have error rates up to 45% when used to estimate light quantum available
Sling Psychrometer
The Seedburo Sling Psychrometer determines relative humidity by measuring evaporation of water into the surrounding air. The unit compares wet and dry bulb temperatures. The %RH is read from the slide rule calculator integrated into the psy
Spad 502 Chlorophyll Meter
The SPAD 502 Chlorophyll Meter instantly measures the amount of chlorophyll or "greenness" of your plants. Nitrogen needs can be assessed by comparing in-field SPAD readings to adequately fertilized check or reference strips. This allows yo
UV Meter
Monitor critical UV radiation. This portable, hand-held meter measures the UV photon flux in the wavelength range of 250 and 400 nanometers in units of µmol m-2 s-1 (micromoles of photons per square meter per second). plants. Use this meter
