|Great for verification of HVAC system performance, IAQ conditions and adherence to guidelines and regulations
When you deal with IAQ studies you need a reliable meter, as IAQ impacts health. This is what TSI 7545 is. I am even more proud of my work now, as I am more confident it helps me improve indoors environmental conditions in work and living spaces.
air comfort and safety
Safety is important to me, when I evaluate ambiental air. Carbon monoxide and a leathal odorless gas, so you need to make sure ambiental air inside homes, offices or commercial buildings are CO free. TSI 7545 measures all ambiental air prameters and CO too. I have been pleased with how accurate it is. Afterall, quality of my work lets me get more jobs without advertising.
so many uses
Use this meter everyday. Covers just about everything you need to measure.
Datalogging is great
Nice to have an accurate model to test for Air Quality parameters. The datalogging is great as it gives tangible evidence to work accomplished and the result in cleaner / safer air quality in the home.
Gereat for checking IAQ and having the ability to calculate CO levels adds some extra safety to the deal.
Just got a few of these in for our guys. Being on a big crew we need tools we can rely on. We have used this tool in the past and loved it so when the time came to replace a few old ones, it was a no brainer to keep them.
Quality product with NIST calibration and accurate measurements – software makes it easy to transfer data to your computer.
Great for IAQ
This meter measures everything you need to know to do IAQ work and get everything inside the building envelope balanced to where you need it. The infrared CO2 sensor is the most reliable kind you can get and I’d guess why the tester is slightly pricier than others. In my opinion it’s worth it for the accuracy and it’s backed by the NIST certification so you know it’s legit.
IAQ best tool
Measures not only CO2, temp and RH, but also CO. This adds a security feature, as CO is a deadly gas. It is quite expensive, but all of my guys want to use it now, as it is so accurate and stores data for reports. I find it very, very reliable.
Helpful to have the CO measurement along with all the IAQ and temp/RH readings. This meter really covers all your bases for working with air indoors.
Very important to have an accurate CO measurement. Really is a matter of life or death. this model is accurate.
TSI is like the Cadillac of testing equipment. Standard NIST calibrated and works like a charm. Great for work involving verifications for insurance purposes.
