Don’t miss testo at the last PHEX show of the year

We’re now less than 2 weeks away from the final PHEX show of the year. So, if you missed us at Alexandra Palace and Manchester, be sure to register for your free tickets to PHEX Chelsea on the 15th & 16th November!

 

 

At PHEX Chelsea you will have another opportunity to get hands on with our new 320 Bluetooth Flue Gas Analyser. Designed to provide the domestic engineer with all the functionality to produce a complete heating system diagnosis, the testo 320 Flue Gas Analyser has a colour graphic display, providing a unique user interface experience to allow simple access to measurement menus for flue gas analysis, draught measurement, pressure, ambient CO measurement, letby & tightness testing, and many more. Use the testo 320 to quickly determine and eliminate malfunctions, monitor legal limit values and spot checks in daily work on servicing heating systems.

The testo 320 Flue Gas Analyser comes as standard with Bluetooth communication to android devices such as a smartphone or tablet device using the testo combustion App. This allows users to control the analyser remotely, view graphical data on set parameters, and also provide fast and efficient reports on measurements direct from site via email.

The 320 can also be equipped with optional probes to provide the ability to carry out gas leak detection on pipework, and also if required measurement of ambient CO & CO2 values.

The testo Smart Probes range makes measurement easier, more mobile and more productive than ever before

 

The eight pocket-sized professional measuring instruments, which can be connected to a smartphone or tablet via Bluetooth, are operated entirely via the free Smart Probes App. Each instrument has been designed for it’s own specific application, measuring temperature, humidity, pressure or air velocity. Competitively priced, testo Smart Probes are the ideal instruments for HVAC contractors with an enthusiasm for technology.

Thermal Imaging for contractors – advantages in a nutshell

For contactors in the Building, Facilities Maintenance, HVAC, and Electrical industries, the ability to visualise each situation you are facing can make a huge difference. Knowing precisely where to start with a job, can save time and effort, meaning you increase efficiency, and ultimately provide a faster service to customers.

Those 20-30 minutes extra spent diagnosing each job soon add up, particularly at busy times of the year when you’ve got a waiting list. With that in mind, a valuable addition to many contractors toolkit is a thermal imaging camera.

But what specific applications is a thermal camera most useful for?

Below we summarise some of the best examples where thermal imaging has time and time again, proved an extremely effective diagnostic tool for contractors:

 

Heating and installation systems

  • Checking radiators for build-up of silt deposits
  • Identifying underfloor heating abnormalities

Electrical Maintenance

  • Identifying overloads, imminent malfunctions or existing defects in switching cabinets and wiring

Construction and Mould Assessment

  • Visualising thermal bridges in buildings
  • Detecting areas that are prone to mould

Leak Detection

  • Pinpointing thermal anomalies in leaking pipes
  • Locating roof leaks

Structural and Insulation Defects

  • Finding insulation defects
  • Checking air tightness of windows and doors

Testo Calibration Services – more than meets the eye

Testo Limited offer UKAS and ISO calibrations on a wide range of instrumentation.

Whilst you may be aware we offer calibration on testo instruments, you may also be interested to know we offer calibration services for instruments from many other manufacturers too!

 

testo-calibration-copy

Testo provide top quality calibration for a huge range of instruments

 

Here are some of the many parameters we supply first-class calibration services for:

 

Track your instrument every step of the way

1. Thanks to testo’s innovative service tracker you can track your instruments online.

2. An email will be sent to you at every stage of the process to update you on the progress of your instrument or track your instrument yourself by entering the serial number.

3. A reminder will then be sent to you before your next calibration is due which, can be handy if you’ve got other things on your mind, so there’s no risk of forgetting.

 

Arrange your instrument collection online

Simply complete an online UPS collection form and we’ll do the rest.

Smart Air Conditioning Commissioning

When installing or maintaining air conditioning systems, it is important to ensure that the installation is running correctly and efficiently. Such commissioning and servicing aim at verifying the appropriate standard of the installation and detecting issues in order to improve and document the performance of the unit.

Especially in times of increasing energy costs, maintaining air conditioning systems is gaining more and more significance. A poorly-performing unit can easily exceed the annual heating costs of a building or amount to twice or three times the costs of a building’s lighting system. [1]

In order to improve the efficiency of an air conditioning system and reduce its energy consumption, it is important to use the right testing equipment, which provides all the relevant information in a simple and reliable way. This makes troubleshooting and performance verification easier and more accurate as it supports technicians in their daily work by improving their productivity and competence.

This trend led Testo to develop and introduce their new range of wireless probes this year, called Smart Probes.

sp-refrigeration-setTesto Smart Probes

This range of 8 handheld measuring instruments connects to Android or iOS smart devices via Bluetooth and communicates with a free App from Testo. Especially the Smart Probe Refrigeration Set, combining two high-pressure probes and two clamp probes, offers all relevant measuring instruments to ensure simple and accurate measurements of actual pressures and temperatures. Using the transferred data, the Smart Probes App then automatically calculates superheat and sub-cooling on the air conditioning system and helps monitoring and controlling them smart and efficiently. The effects of system adjustments can be seen quickly without the need for manual measurements and calculations. Results of the tests are recorded on site in PDF or Excel format and, after adding customer details to the report, can be emailed directly to the customer or to the office for filing.

t605iIn addition to the Refrigeration Set, two Thermohygrometer Smart Probes testo 605i can be a very useful supplement in order to calculate the air conditioning system’s capacity and can give a more comprehensive image of the unit’s efficiency. By measuring the relative humidity and temperature of supply and return air as well as entering the cubic feet per minute, the thermal energy in British Thermal Units (BTU) per hour, is automatically calculated and displayed in the App. This indicates the amount of heat per hour an air conditioning system can remove from an area and, thus, describes how quickly and effectively the unit cools a room. All measured values of the Refrigeration Set in combination with the two Thermohygrometers are displayed in the same App on one portable device and help engineers to work more efficiently and smarter than ever before.

t770-3Measuring an AC System’s Electrical Efficiency

The launch of the new electrical product range, now adds a third key feature to Testo’s smart way of measuring. The electrical clamp meter testo 770-3 offers the possibility of adding all relevant electrical measurements to your other measurements again in the same Smart Probe App. That means, voltage and current measurements enable the monitoring of an air conditioning system’s electrical efficiency. Additionally, the integrated power measurement function allows an automatic calculation of wattage within the app due to parallel voltage and current measurements. This supports engineers in determining the energy efficiency rating (EER) of the air conditioning unit as a ratio of the system’s cooling energy (in BTU/h) to its electrical energy (in Wh).

sp-app-iconThus, by using the same App, Smart Probes and the new testo 770-3 Clamp Meter provide engineers with all the information they need to efficiently measure, monitor and control air conditioning systems and help them to generate a comprehensive report on the unit’s efficiency and total performance.
