PP Systems International, Inc. products

A dedicated, self-contained system for long-term deployment and unattended operation for measurement of soil respiration. Ideal for both spatial and temporal analysis.

Measurement of Soil & Net Canopy CO2 Flux That Is Accurate, Rapid, Reliable, & Affordable. As versatile as it is portable, the EGM-5 Portable CO₂ Gas Analyzer is fast becoming the go-to solution for rapid, accurate survey measurement of soil CO₂ efflux at an affordable price. Simply connect the SRC-2 Soil Respiration Chamber directly to the EGM-5 console and view your data in real time. At the conclusion of each measurement sequence, the results are displayed on a high resolution, touch display with outstanding readability under high sunlight.

A perfect solution for robust, affordable and accurate measurement of CO2. Since 1984, PP Systems has partnered up with many OEM customers offering custom solutions that meet a wide variety of applications. Our SBA-5 CO2 gas analyzer has the enviable reputation for being high quality, reliable, stable, accurate, and versatile. It can be supplied on a printed circuit board (for easy integration into an existing system) or in a convenient, lightweight, rugged, anodized aluminum enclosure.

The WMA-5 is our 5^th generation CO₂ gas analyzer designed for applications requiring high accuracy and control with minimal maintenance. The design of the WMA-5 ensures inherent calibration stability confirmed by over 40 years of experience in gas analysis technology. It features a non-dispersive, infrared measurement technique coupled with microprocessor-based signal processing resulting in precise measurement of CO₂. Our innovative “Auto-Zero” technology and insulated, thermostatically controlled optical bench ensure fast warm-up, long-term stability, accuracy, and analyzer calibration. It also minimizes the effects of sample cell contamination, IR source aging, changes in detector sensitivity, and pre-amplifier gain.

Our TRP-3 Temperature/PAR Probe is available for measurement of temperature as well as PAR (Photosynthetically Active Radiation). It consists of a rugged, aluminum housing with a black foam cover. The TRP-3 includes sample gas tubing to connect to the infrared gas analyzer and a standard tripod thread mount for use with commercially available tripods.

The STP-2 Soil Temperature Probe is a trusted plug and play accessory available for measurement of soil temperature. Electronics are housed in an anodized aluminum enclosure with a stainless steel tip. This rugged sensor is commonly used with the SRC-2 Soil Respiration Chamber and CPY-5 Canopy Assimilation Chamber.

The popular SRC-2 Soil Respiration Chamber is the industry standard for rapid, accurate survey measurement of soil CO2 efflux. The lightweight chamber is constructed of rugged PVC with a convenient handle for placement on the soil surface. A stainless steel ring provides a good seal on the soil surface or on collars.* A built-in temperature sensor measures air temperature near the soil surface a well as an internal fan to flush and mix the air.
