As humans, it is natural to find comfort in routine. We may use the same product for years, merely out of habit, without taking into consideration that there are new products on the market that better serve our needs. Presscision’s PPT innovative product is a portable, digital test instrument that provides automated pressure and temperature testing for a multitude of industries, including plumbing, HVAC, gas utilities, fire suppression, medical and marine.
The PPT instrument was designed with the user in mind. Its capabilities far exceed those of the traditional analog pressure gauge it replaces. Naturally, these advanced capabilities come with a higher initial purchase price for the user. However, when making a purchase decision, factors such as the true cost of ownership, and added value should be considered.
When viewed as a long-term investment, the Presscision instrument’s true cost of ownership is significantly less than that for an analog gauge, as seen in the following evaluation:
Analog gauges are considered “consumables”. Due to the high failure rate, many firms choose to replace analog gauges after each regulatory test.
The operating life of the Presscision PPT instrument is 10 years or longer.
Small plumbing firms can easily consume 10 analog gauges per year, resulting in a yearly operating cost of $600.
Large plumbing firms can consume over 100 gauges per year, resulting in a yearly operating cost of over $5,000.
Amortizing the cost over a 10-year lifetime results in a yearly operating cost of less than $200.
The cost of ownership does not factor in the added value that the advanced features and performance of the Presscision instrument delivers to the owner over the lifetime of the instrument. The added value relative to the traditional analog gauge can be in the form of tangible (measurable) benefits and intangible benefits.
The following comparison between an analogue gauge and the PPT Instrument reveals the significant tangible benefits of the PPT instrument that are not captured by the simple cost of ownership comparison.
Measures single static pressure over a single pressure range.
The PPT instrument is a multi-purpose test instrument that can accurately measure and monitor pressure, ambient temperature and water temperature. Monitoring features include: transient pressure monitoring and capture, long term pressure and temperature monitoring, and multi-pressure measurement.
Fundamental instrument accuracy is typically +/- 1%. However, human interpretation of an analog gauge introduces significant levels of inaccuracy that is difficult to quantify.
Pressure sensor accuracy of +/- 0.25% (+/- 1% including thermal effects). Each pod comes with a calibration certificate that provides proof of accuracy relative to a traceable pressure standard.
No data recording capabilities.
Records comprehensive data record for each test in permanent, tamper-proof memory. Each record provides thorough documentation of the test conduct and results.
No test reporting capabilities.
Detailed test report generated for each test. Reports can be printed at job site (or at a later time) using the built-in printer.
Experience has shown that analog gauges have great difficulty resolving small changes in pressure (due to leaks) over typical test times. For jobs that involve multiple stages of testing, often times leaks remain undiscovered until the late stages of the testing process. Identifying the source of a leak at a late stage of testing can be a difficult, time-consuming, and costly.
The Presscision PPT instrument’s accurate and repeatable measurement capabilities combined with digital readout has demonstrated the ability detect small leaks that would otherwise go undetected by an analog gauge. Detecting leaks earlier in the test process makes the task of locating the leak much faster, saving time and money.
A common failure mode of analog gauges is the failure to “return to a 0.0” meter reading after removal of pressure from the device under test following test completion. This failure mode results in a failed test, with significant ramifications to job schedule and cost.
The Presscision PPT instrument uses modern, digital transducers for accurate, repeatable measurement of pressure and temperature. PPT users can go into a regulatory test with high confidence that a test will not fail due to failure of the instrument itself.
By it’s very nature, an analog gauge does not provide any form of liability shield to the user. From undocumented sensor accuracy to the lack of test records, using an analog gauge leaves the user with no tangible proof of the results and accuracy of past tests.
The Presscision PPT instrument automatically generates documented test records that provide proof of measurement accuracy, test conduct, and results. These records and associated test reports provide a high level of protection from potential litigation.
Presscision Incorporated has a keen understanding that a reliable testing instrument is vital to a plumber’s job. Therefore, we have developed an instrument that is carefully tailored to provide ease of use to our valued customers. We understand that time is of the essence and it is important that testing is accomplished accurately and efficiently.
Our mission at Presscision is laser focused on providing industry with modern tools to increase safety, improve testing efficiency and reduce exposure to liability. If interested in learning more about its capabilities, and to try a state-of-the-art device, please give us a call.
