Reach in Plant Growth

These chambers are frequently used for research applications such as lighting for vascular plants to facilitate standard plant production, plant pathology research and seed germination and development. The chambers are available in multiple sizes.

Compare your requirements to the specifications listed here.

Here are just some of the quality features found in our Reach-In Plant Growth Chambers:

Sturdy 18 and 22-gauge steel interiors and exteriors built to last much longer than less sturdy aluminum options.
Utilizes both fluorescent and incandescent lighting for uniform light intensity and optimal plant growth.
Dimmable ballasts, alone or in combination with light sensors, for precise irradiance control.
IntellusUltra Controller allows you to control temperature, humidity (optional), CO2 (optional) and lighting. IntellusUltra Web Server (optional) lets you program and monitor your growth chamber from your desk, laptop or phone.

Patented High Efficiency Lamp Bank (not available on all units)

At Percival, we engineer chambers to be easy on our environment while supplying you with research standards you’ve come to expect (and maybe some you haven’t). This is why our patented lamp banks require less energy and radiate less energy. The unique design lets you experience maximum light irradiance without sacrificing optimal temperature.

Percival’s exclusive lamp bank features include:

The most energy efficient lamps in the market.
Higher light intensity with less energy consumption.
Stable light intensity from T5 fluorescent lamps regardless of temperature conditions inside the chamber.
Better vertical temperature gradient inside the chamber.
Less flickering at settings near the lower end of the dimming range (when using optional dimmable light fixture).
A smaller refrigeration system resulting in reduced electrical and water consumption.
Higher light intensity with fewer bulbs, resulting in less heat introduction into the chamber.
Reduced heat rejection to the ambient which results in smaller building HVAC.

Energy Savings Example:

UNIT: PGC-10 utilizing the patent-pending high efficiency lamp bank
USAGE: Lights energized for14 hours per day in a region with electrical costs of 10 cents per KW/hr
RESULTS: Cost savings of over $1750 annually in energy consumption

IntellusUltra^™ Controller and Optional IntellusUltra^™ Web Server

"The power of remote monitoring and precision control anywhere you are!"

The IntellusUltra lets you control temperature, humidity, CO2 and lighting from the outside of any Percival chamber. When combined with the IntellusUltra Web Server, these applications can be controlled remotely using a Windows based PC or Mobile 5.0 Treo 700 WX Palm Smart Phone. The Web Server requires a network internet connection but no other software.

The IntellusUltra features:

Single board solid state design
Low energy consumption
Highly visible display with LED indicators
Highly accurate PID temperature, humidity, auxiliary/lighting control
16 total programmable on/off outputs for lighting or other applications (7 of these outputs are configurable for dimmable lighting)
Integrates with Intellus Web Server (optional) for remote monitoring/programming and email alarm notification via Windows based PC (requires Internet Explorer 6.0+) or Windows Mobile 5.0 Treo™ 700 WX smart phones
Multiple programming styles including diurnal, 24-hour based real time or elapsed time
Non-ramping and ramping control
Store up to 560 total program steps and 70 programs
Program sequencing
Multiple alarm settings provide experiment protection and notification of specific chamber events
Calibration offsets
Four password protected security levels
Non-volatile memory for programs and parameters
Battery backup for volatile memory

WeatherEze^®

"The next generation of chamber control software."

Where do you want to be today? South America? Africa? Norway? No one else gives you such an advanced level of power for precision chamber control.

Download PDF brochure.

WeatherEze allows your chamber to have real-time duplication of the temperature, relative humidity, and solar lighting for any global location. Two powerful options are available.

The Simulated Environment

This option allows you to select any location on the globe. This program will simulate the average weather and incident radiation conditions at the site with a user-selected starting date and time.

The Real-Time Control

Program the exact real-time weather conditions for any location across the globe. Some limitations may exist due to the availability of real-time weather data in some areas.

Additional cutting-edge features of WeatherEze include:

Easy data entry based on latitude and longitude or by simply clicking on a map.
METAR Data link allows for constant updating of actual weather conditions.
30-year average climate conditions are also available if real-time conditions are not desired.
Set-it-and-forget-it settings let the chamber run itself without further intervention.
Complete data collection of set points, current conditions and METAR data are downloaded into CSV files for processing and documentation.
Real-time daily graphs of temperature, relative humidity and CO2 let you see at a glance the actual set points and values as well as what they will be for the day.

Chamber requires the current Intellus Ultra, Intellus Web Server, and specific options for proper functionality. Please contact factory for details.

WeatherEze is the result of a cooperative research and development agreement (CRDA) with the United States Department of Agriculture-Agricultural Research Service to incorporate their environmental simulation models into this revolutionary chamber control software.
