PP Systems - Model TARGAS-1 -Portable Photosynthesis System
The TARGAS-1 Portable Photosynthesis System is designed for basic research and features a very high technical specification – one that rivals some of our competitor’s “High-Level Research” instruments. It is an extremely user-friendly instrument making it an ideal choice for teaching purposes and can be used in both the laboratory and field.
The versatile TARGAS-1 is capable of measuring:
- Photosynthesis
- Soil Respiration
- Canopy Assimilation
- Soil Temperature
- PAR (Photosynthetically Active Radiation)
- Temperature and PAR
- Small Volume Sampling
The TARGAS-1 console is compact, lightweight (2.1 kg), and packaged in a rugged, aluminum enclosure with a shock-absorbing polyurethane base, making it extremely robust and reliable under harsh environmental conditions. It incorporates two non-dispersive infrared gas analyzers for CO2 and H2O ensuring accurate measurement and control of both CO2 and H2O. An internal air supply unit provides accurately controlled reference air to the leaf cuvette, and another pump draws the sample (analysis) air to the gas analyzer. Both pumps are user-controlled and two internal electronic flow sensors ensure accuracy.
The TARGAS-1 gas analyzers should not require frequent recalibration, although we do recommend periodic checks to confirm system integrity. Both the CO2 and H2O gas analyzers employ a non-dispersive, infrared measurement technique, coupled with microprocessor-based signal processing, to achieve excellent stability and specificity to CO2 and H2O. Our innovative “Auto-Zero” technology ensures fast warm-up, long-term stability, accuracy, and analyzer calibration. It also minimizes the effects on span gas sensitivity, sample cell contamination, IR source aging, changes in detector sensitivity, and electronics.
All electrical and gas connections, USB interface, power, and desiccants are conveniently located on the console rear panel.
- Lightweight console (2.1 kg) and leaf cuvette (0.7 kg)
- High precision, compact, non-dispersive infrared gas analyzers for both CO2 and H2O
- Automatic temperature and pressure compensation
- Control of CO2 and H2O
- Control of light (light unit optional)
- Powerful, internal rechargeable battery providing up to 10 hours continuous use
- Large touch display with excellent sunlight readability and optimized viewing angle
- Numerical and graphical presentation of data
- Built-in air supply unit and sampling pump with electronic flow sensors
- Wide range of accessories and sensors available
The TARGAS-1 is perfectly suited for applications that demand portability and a high degree of accuracy and control with minimal maintenance. The instrument is designed to ensure inherent calibration stability confirmed by many years of experience in gas analysis technology.

Touch Display
An Innovative, large, touch display (EPD) features simple and intuitive system navigation and it offers excellent viewing under high sunlight.
The PLC Leaf Cuvette is extremely versatile and light weight (0.7 kg) making it ideal for measurement on a wide variety of vegetation including broad leaves, narrow leaves, grasses and small needle conifers. It includes sensors for measurement of air temperature and PAR. All leaf cuvette materials are carefully selected to minimize influences such as infrared radiation, water sorption, CO2 effects and leaks. The leaf gaskets provide an air-tight seal without causing damage to vegetation.
An optional, low power LED-based light unit is available for light control if required. It is a useful option for light response curves and to simply have on those cloudy days. The unit clips onto the head of the PLC5 Leaf Cuvette and it can easily be removed for measurement under ambient conditions.
- Type: LED (white)
- Measurement Range: 0-2500 μmol m-25-1
