Tools produced by Testo have served various industries for decades. Their measuring tools are widely used for differing applications worldwide. However, their specialty lies with HVAC/R technicians. In the field where conditions are tougher and customers tend to be more demanding such as HVAC/R industry, Testo offers their best products and services.
Professional heating measurement technology for every requirement.
Maintaining and fixing the heating system is far more complicated than what most people think. There are many factors to consider which all lead to the optimal performance of the unit and safety. It is necessary to check the functionality of the unit, do some adjustments and measurement activities on gas-fired systems, oil and solid fuel systems, both during commissioning and at regular intervals. Some of the things in the must-check list are flue gas analysis, differential pressure measurement, leak localization and tightness testing, flow temperature measurements, and more. All the mentioned tasks are quite demanding but with Testo’s heating solution the job can be done more professionally, reliably, and faster.
Indoor Air Quality
Checking the quality of indoor air in the office may sound like a nuisance to the management however, it offers long-term benefits to your employees and profits. Ensuring that the indoor air is in good condition and is in a comfort level allows people to work more efficiently and reduces the possibility of staff-shortage due to sickness.
