Checking the function of underfloor heating
Temperature measurement of underfloor heating when it is installed or when maintenance or servicing is being carried out. Ensuring the underfloor heating is functioning properly by measuring the temperature at various points on it.

Advantages of the Testo 835-T1:

• Fast, easy (non-contact) checking of underfloor heating
• Fast saving and documentation of data for later report writing
• Clear marking of the measuring range by 4-point laser

Checking switch cabinets, fuses and fitted cables
Temperature measurement of electrical installations when they are installed or when maintenance or servicing is being carried out. Ensuring the electrical components are functioning properly by measuring the temperature at various points on them.

Advantages of the Testo 835-T1:

• Fast, easy, non-contact checking of electrical components
• Fast saving and documentation of data for later report writing
• Clear marking of the measuring range by 4-point laser

Checking ventilation components
The testo 835-T1 is ideally suited for measuring the temperature of ventilation components, for instance at duct outlets and on ventilation ducts. Assessing the ventilation duct's insulation and ensuring the ventilation system is functioning properly by temperature measurement.
