The AP4 Porometer measures stomatal aperture in terms of leaf conductance to water vapour.
This is a major determinant of water loss from plant leaves and of CO2 uptake in photosynthesis.
The innovative design of the AP4 provides users with logical, convenient operation and a comprehensive range of features and functions. Key benefits include an automated, rapid cycle that gives accurate temperature compensated readings, and a straightforward highly effective field calibration system.
In the video below (click on image to access) Delta-T Devices Technical Specialist, Tony Peloe, gives a detailed demonstration of the AP4’s capabilities.
Delta-T Devices Founder, Ed Potter, shared a platform with a number of prestigious academic speakers to pay tribute to the life and work of Professor John L. Monteith at the 2013 American Society of Agronomy Annual Meeting in Tampa, Florida last November.
John, who passed away in July 2012, was probably most renowned for the Penman-Monteith equation for evapotranspiration, and for the original edition of Principles of Environmental Physics. He had a long and distinguished career developing and applying...
POROMETER will attend Filtech 2013 on 22-24 Oct 2013, in Wiesbaden (Germany). Our managing director, Danny Pattyn, will give a presentation on "Capillary flow porometry a tool for the characterisation of pore size distribution of through pores in filters and membranes" at session M3 (16:45-18:00) on 22nd October 2013. Visit our booth for more information on our products and services. We look forward to meeting you at Filtech 2013!
After we attend the Japanese exhibition AGRI world last month our Japanese agent put a new order to LeBio. They ordered one pallet of 32 mesh light adjusting magenta net to let their Japanese customer try our net. LeBio ship it urgently to Japan.
Our Taiwanese customer in Meinong , Kaohsiung using our 32 mesh light adjusting magenta net for their greenhouse. They only use the net to cover the roof top. They sowing the see on 10th October and they harvest their crop at the end of October.
Pakchoi-very tasty

The best defense against fungal infection for high-value, susceptible greenhouse crops is to create environmental conditions that promote a healthy, dry crop that is also hostile to fungal proliferation. This means controlling temperature and humidity such that water is notaccumulating on the surface of the plant tissue. Ideal conditions are those where the vapor pressure deficit is sufficiently high for water vapor to leave the foliage and enter the air, avoid dew formation at all times, and avoid water dripping/s...
At Thanksgiving, many Americans look forward to eating roast turkey, pumpkin pie, and tangy red cranberries. To feed that appetite, cranberry farming is big business. In Massachusetts, cranberries are the most valuable food crop. The commonwealth’s growers provide one-fourth of the U.S. cranberry supply.
Water plays a big role in cranberry farming. At harvest time, cranberry growers flood their fields (cranberry bogs) so the berries will float for easy gathering. The growers may also flood their fields to...
