Parameter units are simplistically and perfectly designed to fit any company’s needs for temperature and humidity controls. The units are very reliable and the quality of the product is top notch. A superior company from sales, manufacturing, delivery, installation, qualification and customer service.

I have been working with Parameter’s chambers now for the past 4 years with excellent results. My original project to install two new walk-ins led to an additional five walk-ins plus reach-ins, because of their ease of use, reliability, and durability. Operating the chambers couldn’t be easier, and all components are located for simple maintenance and service access. Parameter’s employees are great to work with and very responsive to our needs.

I first learned of Parameter while attending a stability seminar in 2006. PGC was one of the many vendors present at a stability confer. I was impressed by the capabilities of their walk-in stability chambers. Their tight tolerances for temperature and humidity uniformity were better than their competitor, which sold me on their chambers.

When we had the opportunity to purchase our first walk-in chamber in 2010 for 25C/60% RH storage, Parameter was the only vendor I considered. We have subsequently purchased a second walk-in chamber for 40C/75% RH storage and only recently purchased a reach-in stability chamber. Parameter’s chambers have been very reliable with minimal issues and easily maintain ICH guidance for temperature and relative humidity.

We have a Parameter Walk in stability chamber installed in 2018. The unit is working very well since the installation. The unit operation is simple and the control is very precise. The unit requires minimal maintenance. It is a very reliable product for a very critical application.

The Parameter Generation and Control conditioner allows us to manage our lab temperature and humidity on a continuous basis.  Unlike other systems, that cycle on and off based on deviation from set point, the PGC system is continuous, reducing our variation around target RH by roughly 70%.  The calibrated control probe meets our ISO requirements.  The preventative maintenance program helps us keep our system optimized.

We provide temperature-controlled storage to the pharmaceutical industry in Ireland. We store samples at a range of specific temperatures for an exact period of time, and then return the samples at set intervals to the clients for testing.  

From the first day of operations in 2013, we have relied on Parameter equipment to control the temperature and humidity in our chambers. The chambers range in size from 200 ft3 to 3,000 ft3.  We operate 32 stability chambers in our facility in Ireland, and each unit is powered by a Parameter stability unit.  

We would have no hesitation in recommending Parameter stability units, as they are the industry leader in temperature and humidity control. The simplicity of control and operation of the units make them very attractive to our operation. With a huge range of options available for volume of chambers and temperature conditions, Parameter is the only choice for us.

We have had a Parameter Generation and Control chamber to moisture condition structural wood products in our lab since 2000.  With the exception of a one month break for a 500 mile facility move/re-installation six years ago, it has run continuously for more than 20 years.   Beyond normal preventative maintenance, the only service need I can remember over that entire time was the replacement of a heating element that reached the end of its reasonable service life.  That chamber has been one of our most dependable pieces of equipment.  When we needed a second one 4 years ago, I did not consider any other vendor.  The second chamber has been just as good as the first…providing outstanding, trouble-free service.

Parameter is the company of choice for providing reliable environmental chambers. I am confident I am receiving a quality product.

Their knowledgeable staff is an extra plus to their service. On occasion we have called the service techs to help trouble shoot an issue. They are available by phone to provide the needed assistance. Their expertise is unmatched and a deciding factor when the need for more environmental chambers were required for our expanding business.

We were looking for a company that could build us a walk-in environmental chamber to our specifications. We found Parameter to be very knowledgeable and reasonably priced over some others we had quoted our needs.   Delivery and set up was as planned and quick. That was 5 years ago, and the unit is work great. They have a customer friendly staff that is highly knowledgeable about their systems and can typically solve a problem over the phone. We have subsequently bought a second, slightly smaller unit for a different facility. We highly recommend Parameter for walk in environmental chambers.

I have been working with PGC for about ten years now. I deal with a lot of outside vendors on a day-to-day basis at my job, and it is easy to say PGC is by far one of the best vendors to interact with. Every employee I have met has been knowledgeable, helpful, and friendly. They are quick to respond with any questions or issues you may have with your chambers. It is a pleasure to work with every member of PGC.  When I started working with PGC, we began with the purchase of three stability chambers and have gradually purchased five more through them because of the exceptional reliability and impeccable construction.  The design of the chambers is user friendly, and they maintain temperature and humidity better than any other vendor’s chambers I have had experience with. I highly recommend PGC, not only for their product but their amazing team.
