Apogee Instruments Infrared Radiometers (IRRs) measure surface temperature by converting thermal energy radiated from any surface in its field-of-view (FOV) to an electrical signal with a response time less than 1 second. Each IRR carries an impressive uncertainty of 0.3C at 95% confidence to ensure accurate measurements. The resilient 8-14 m germanium window corresponds to the atmospheric window in order to minimize the effects of water bands below 8 m and above 14 m. The radiation shield, included free of charge with every IRR, insulates your sensor from rapid temperature changes, thus reducing noisy measurements.

State of the Art Optical Field MeasurementMeasures chlorophyll concentration from leaves without damaging plant materialLightweight design facilitates hand-held measurements in the fieldLarger sampling area integrates a larger portion of leafStores over 100, 000 data points, more than most metersIntegrates with third-party GPS to mark locationMeter calculates average of user-defined sample sizes to evaluate overall plant health

The MO-200 is designed to measure 5 100% oxygen while the handheld meter displays and stores measurements. The wide measurement range allows it to be used for applications either in the soil or in the lab with the available diffusion or flow-through heads. The sensor is calibrated to ambient air making it very easy to calibrate. An aluminum housing that is filled with epoxy allows the sensor to withstand harsh conditions.

For long-term monitoring of chlorophyll fluorescence in the field Robust and versatile measuring system to fluorimetrically survey photosystem II efficiencies over periods of weeks and months even under harsh weather conditions. For basic and applied research; plant screening Fully computer controlled; optional ultra-mobile PC for field work and touch screen operation Optional accessories for algae and cyanobacteria

The CI-202 Portable Laser Area Meter uses advanced laser technology to provide researchers with a precise and convenient method of measuring leaf area. The high-resolution laser scanner, data logger, and display are enclosed in a hand-held self-contained unit. Ideal for field use, the scanner head and palette format base. Researchers can perform non-destructive measurements on the leaves of living plants by simply sliding the scanner over the leaf, enabling collection of data from the same plant, or even the same leaf, throughout its life span. Precise leaf area measurement of tender leaves is possible by using a transparent sheath for the leafs protection

Salinity measurements are an important aspect of soil, crop and environmental protection, research and management. A new Salinity Meter manufactured by ICT International offers scientists and environmental managers a highly accurate, low cost, plug and play solution to measure salinity in the field. The system consists of a meter with LCD display and spreadsheet software. The Software allows conversion of the manually recorded values to soil salinity in dSm for each individual soil salinity sensor.

This state-of-the-art, gel-filled low maintenance pH-electrode with excellent pressure resistance is specifically developed for reliable measurements in bioprocess. With pressure resistance of up to 6 bar overpressure and patented silver-ion trap to prevent fouling of disaphragm in sulfide-bearing media, the glass body pH electrode can be used on an universal basis in bioprocess applications such as cell culture and fermentation.

Apogee Instruments quantum sensors measure photosynthetic light levels in both air and water, combining accuracy and durability at a competitive price. The sensor heads feature a unique blue diffuser that reduces spectral error to less than 5 % for sunlight (direct, diffuse, under plant canopy, reflected from plant canopy) and common electric plant lights (fluorescent, metal halide, high pressure sodium), and less than 10% for LEDs (blue, green, red, cool white, neutral white, and warm white).
