![]() In addition to diagnosing issues with HVACR equipment, smart tools can also diagnose themselves. “Using a mobile app and Bluetooth connectivity, a technician can place an instrument in an optimal testing location and remotely control and monitor the instrument from a safer or more convenient location,” said Harry Ostaffe, director, product management and marketing, Bacharach. Their PCA 400, a four-gas, portable combustion analyzer, uses Near-Field Communication (NFC) technology and pre-calibrated B-SMART sensors, eliminating the need to apply any calibration gas, keeping the units in the field and in proper service condition. That’s something that Bacharach is doing via products that measure the combustion and emissions from sources, such as furnaces, boilers, generators, and engines. Taking out some of the manual work can also make for heightened safety. ![]() “These tools save time and money on the job by making calculations quicker, reducing steps by showing all sensor data on your mobile device, allowing data sharing with other experts to help solve the problem at hand, and reducing callbacks to the job,” said James Ruether, product manager – electronics, Sporlan. Tools like Sporlan’s SMART and SMART Pro/R sensors and apps, two lines of Bluetooth-enabled pressure and temperature sensors, provide automatic calculation of superheat and subcool measurements for over 130 refrigerants. “The charts are right there at your fingertips, in the app, so you don’t have to go to a second location to check temperatures and pressures for the refrigerant. “You can plug in what refrigerant you’re dealing with - 22, 410 - and it’s already giving you what your pressure should be,” Ellingson said. Smart tools also help increase competency by reducing the need for manual calculations, helping technicians avoid human error. It makes the technician seem more competent, being able to provide data to the homeowner or property manager.” “Versus in the past, they’d have to leave it in their truck, go back to the office, take data written down and enter it, then send it to the customer. “It can be exported into a CSV file, like an Excel sheet or PDF, and you can print it out and hand that to the customer on the spot,” said Ellingson. It can be stored in all three areas - or put to immediate use, which saves time for contractors. ![]() Data collected via a smart reader can be pushed to the app, the smart device, and the cloud-based system.
