testo Smart vs GasTest Log

- All in one: The testo Smart App supports you with measurements on refrigeration, air conditioning, and heating systems, as well as in ensuring the safety and quality of food and frying oil, and in monitoring indoor climate and storage conditions. - Fast: Graphically descriptive display of measured values, e.g. as a table, for quick interpretation of results. - Efficient: Create digital measurement reports including. photos as PDF/ CSV files on site and send them via e-mail. The testo Smart App is compatible with the following Bluetooth®-enabled measuring instruments from Testo: - Thermal imager testo 860i for smartphones - All Testo Smart Probes - Digital manifolds testo 550s/557s/558s/550i/570s and testo 550/557 - Digital refrigerant scale testo 560i - Vacuum pump testo 565i - Flue gas analyzer testo 300/310 II/310 II EN - Vacuum gauge testo 552 - Clamp meter testo 770-3 - Volume flow hood testo 420 - Compact HVAC measuring instruments - Frying oil tester testo 270 BT - Temperature meter testo 110 Food - Dual purpose IR and penetration thermometer testo 104-IR BT - Data loggers 174 T BT & 174 H BT - Online data loggers testo 160, testo 162 & testo 164 GW Applications with the testo Smart App Refrigeration systems, air conditioning systems and heat pumps, heating systems, indoor air quality: - Leak test: Recording and analysis of the pressure drop curve. - Superheat and subcooling: Automatic determination of condensation and evaporation temperature and calculation of superheat / subcooling. - Target superheat: Automatic calculation of target superheat - Automatic refrigerant charging by weight, by superheat, by subcooling, and by target superheat - Vacuum measurement: Graphical progress display of the measurement with indication of start and differential value Indoor climate monitoring: - Indoor air quality: automatic calculation of the dew point and wet-bulb temperature - Temperature, humidity, lux, UV, pressure, CO2: the right data logger for every application – from a single solution to an online monitoring system" Ventilation systems: - Volume flow: After the intuitive input of the duct cross-section, the app calculates the volume flow fully automatically. - Diffuser measurements: simple parameterisation of the diffuser (dimensions and geometry), comparison of the volume flows of several diffusers when setting up a ventilation system, continuous and multi-point average calculation. Heating systems: - Flue gas measurement: Second screen function in combination with testo 300 - Measurement of gas flow and static gas pressure: Also possible parallel to the flue gas measurement (delta P) - Measurement of flow and return temperatures (delta T) Thermography: - Determining Delta T on heating, refrigeration/air conditioning, and industrial systems - Detecting hot/cold spots - Assessing the risk of mold Food safety: Temperature Control Points (CP/CCP): - Seamless documentation of measured values to fulfill HACCP specifications - Individually definable limit values and measurement comments within the App for each measurement point - Reporting and data export for regulatory requirements and internal quality assurance Frying oil quality: - Seamless documentation of measured values as well as calibration and adjustment of the measurement instrument - Individually definable limit values and measurement comments within the App for each measurement point - Reporting and data export for regulatory requirements and internal quality assurance --------------------------------------------------------- Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://www.testo.com/en/company/privacy-policy-app

Run the gas piping pressure test and hand the inspector a certificate. GasTest Log times the code-required hold, captures a start and end gauge photo as proof, and exports a one-page, code-cited PASS/FAIL report — right from your phone. It does NOT measure pressure. Your gauge does that. GasTest Log times the hold, documents what you read, and turns it into a clean certificate — so a missed inspector visit no longer means a re-trip. HOW IT WORKS • Pick a code preset: single-family 3 psi / 10 min, elevated 2-lb, commercial (IFGC — ½ hour per 500 ft³ of pipe), UPC 10 psi / 15 min, UPC welded 60 psi / 30 min, or custom. • Photograph the gauge to start a wall-clock countdown with haptic checkpoints — keep working, it holds time even with the screen off. • Photograph the gauge again at the end. Enter your start and end readings. • You attest PASS or FAIL. Export the certificate. THE CERTIFICATE • Date, address, permit, technician, license, and company. • Gas type, medium, required pressure and hold, your actual hold time, and start/end readings. • Side-by-side start and end gauge photos as tamper-evident proof. • The governing code citation (IFGC 2021 / IRC / UPC) and the AHJ acceptance line. BUILT FOR THE TRADE • Works fully offline. No account, no sign-in, no cloud. • Camera + optional location only. Your photos and readings never leave your phone. • No Bluetooth manometer required — use the mechanical gauge already on the pipe. A TOOL, NOT A CODE AUTHORITY Test pressures and hold durations follow the model codes (IFGC/IRC, or the UPC where adopted) — local amendments vary, so always confirm with your AHJ. The app does not measure pressure or decide pass/fail; you read the gauge and attest the result. PRO A one-time unlock — no subscription. Export the certificate PDF, add your company branding, and keep a saved history of every test. No ads. No tracking. No account. Time it. Photo it. Prove it.
