“I have been in charge of installing and maintaining three of Rel-Tek's Millennia-DX carbon monoxide monitoring systems at three of our mines for over a year now. I would like to thank Rel-Tek for producing a product as dependable as the ones they provided for our operations. I have been informed by an associate of mine using a competitor's CO system, that they experience false alarms due to interference of their radios and wireless tracking system. I have not once had a false alarm at any of my three mines. The Rel-Tek CO systems have been working perfect for over a year. The CO sensors and communications cables are as close as 2 feet of our tracking system radios with no false reading. And, communications is so much faster than the competitor's. The Millennia-DX system responds in just one second of detecting CO. If there is anyone looking for a CO system that is fast and trouble free, they need to contract Rel-Tek. From start to finish, the modular Millennia-DX systems were easy to setup, operate and maintain. If I have a question or problem, Rel-Tek's service staff is excellent. A phone call to the plant, and they walk me through any issue I might have. Not so with the competitor's system, I'm told, where service is difficult to obtain. I personally want to thank the Rel-Tek support team for all the help they have provided to me. I am well pleased with our Millennia-DX systems and am happy to say so in writing.”

“Just a quick note to let you know how much I appreciate the Rel-Tek equipment here. I tell everyone, if I were designing a facility I would specify Rel-Tek. To date we have had zero equipment failure. I have had occasion to call tech support with questions and they have always given me the answers I needed."

“The Millennia-DX, GasBoss and MagiKal equipment has performed flawlessly since being installed by Rel-Tek [basic system dates from '98]. We are very satisfied with both products and service. We have had no problems with sensors or telemetry since they were installed. The [auto-cal] tanks have not had to be replaced since the system was upgraded [with MagiKal in '03]. There has been a significant reduction in maintenance since installation of the MagiKal system. The automatic calibration utility has provided noticeably better sensor management then the previous manual system. I would highly recommend Rel-Tek to my peers and colleagues. Using Rel-Tek for our methane monitoring needs has been one of the best decisions made by this agency."”

“I feel the sensors are reliable with or without MagiKal automatic calibration. [System dates from '95; upgraded twice, adding Magikal in '01]. We automatically calibrate [38 CH4 and 18 CO] sensors monthly, and our tanks last a year. Products are very reliable and technical support is outstanding. They are very courteous and responsive. Magikal reduces the amount of time spent on calibrating every sensor manually. ”

“The Rel-Tek [CH4] sensors work very well, and the support has been helpful, although we truly needed very little, as the system has performed without failure. It actually performs better than expected. ”

“The equipment is working as we were told it should. We do an auto-calibration once a month and we have only had to replace each set of [cal-gas] tanks once so far [in four years]. I believe the auto-calibration virtually eliminates human error. We have always been able to call and get answers to any questions we had. I can only speculate as to whether our maintenance/labor cost would be different without auto-calibration, because we never operated the system without it. -- but to manually calibrate [37] sensors monthly would seem to be very labor intensive. I would expect to experience problems with human errors and missed schedules as well. All the communications/control panels have performed without incident over this same time period. I feel the Rel-Tek system has been a good investment for us, and I would recommend this product to anyone who has similar needs. I have confidence in the Rel-Tek product. ”

“We highly recommend this system. I am very happy with your product and the response from your technicians, when I called with concerns. I wish you well at your new facility and thanks again for all of your help. ”
