Customer Testimonials
The Nutech 3000 TVOC Analyzer was a truly remarkable product. It gave us the ability to use the 3000 in multiple locations due to portability and battery operation. The locations did not have readily available power. We were able to confirm our reading rapidly at our stack outputs. We were able to take reading in multiple other locations here at the plant to find out where we were getting a higher VOC readings. The 3000 allowed us to adjust our process to lower the VOC output.
This machine was truly portable which allowed one person to use the 3000 and take very fast reading without the help from others. This was really the best thing because some of the places that the instrument was used at our plant were just big enough for one person.
The meter’s sensitivity and state-of-the-art technology gave me capabilities that weren’t possible with other machines. Not only did it provide lightning-fast test results, but the meter heated up quickly and maintained rock-solid stabilization during readings, meaning that I didn’t have to spend as much time and labor monitoring and fixing different factors that could cause inaccuracies. With the results I’ve received in the use of this instrument, I know that long term use of this meter would help our company save revenue and manpower without sacrificing quality because of its speed and accuracy.
What we found is this meter, with its capabilities, along with its small and portable design, has truly surpassed all of our expectations and needs. Even more importantly, the cost of the unit compared against its capabilities is very low given the high costs of other FID units on the market.
The following investigation was conducted to evaluate the efficacy of pairing Restek products with the Nutech 8900DS preconcentrator to meet the five most pertinent criteria of Method TO-15. Results demonstrate that the combination …. easily meet all of the criteria for TO-15 VOC analysis.
We have done some testing with the unit and found it to work well for some of our applications. We tested sampled concentration levels of about 50 VOCs that we commonly analyze and found no evidence of sample contamination – a challenge we have had in the past with another system. We also found the system to work reliably collecting a series of short samples.
