Probes sold separately The testo 635-2 temperature and moisture meter can be used to carry out a variety of different measurements. The 635-2 has the capacity for two connectable sensors and three temperature / moisture wireless sensors. Wireless devices are picked up through an optional wireless module with a range of up to 65 feet. A wide range of optional sensors and probes provide information on:
Relative humidity
Material moisture
Material compensation moisture
Pressure dew point in compressed air systems
HTC value
Air temperature
Surface temperature
Core temperature
Absolute pressure
Rugged. Practical. Easy to use. The testo 635-2 can display min/max/avg values, and calculate the dew point difference between the indoor air and the surface of a wall, enabling users to analyze moisture levels at ceilings and walls. Individually configured characteristic curves ensure the material moisture content is displayed reliably. Both the meter and the menu guide are simple and comfortable to use. A backlit display allows you to read the measurements in poor lighting, and a rugged case protects the meter against impact. Saving, transferring, printing out data - easy as pie Save measuring sites and allocate measuring data to the relevant site. Create individual profiles to perform parallel long term / material moisture measurements. Save up to 10,000 readings (individual measurements and series) to your meter. There’s also a USB cable and software for transferring your data comfortably to your PC. And last but by no means least, the turbo printer (optional) provides you with on the spot printoutsThe moisture measurement establishes readiness for flooring; liability for the flooring is thus transferred to the respective trade installing the flooring. An important part of this work is therefore documentation and assurance in the testing for readiness for flooring. What is the extent of moisture damage and what consequences can be expected in terms of time and costs? These questions have to be answered in order to decide which auxiliary tools and materials are to be used to speed up the drying process. The t 635-2 and attachment scatter field probe can be used to measure the moisture in the construction material. Using a thin moisture probe combined with the testo 635-2 the moisture of construction materials can be determined by means of an equilibrium moisture measurement. To do this, the probe has to be inserted in a borehole in the material being measured and sealed. The relevant material characteristic can be manually entered into the device or via software. After several hours, equilibrium with the material has taken place and the testo 635-2 displays the material moisture. Measuring material moisture Monitoring the moisture in construction materials and different timber is an important part of everyday work in the most diverse areas. For many users, measuring the material moisture as quickly and as non-destructively as possible is crucial. Whether it is used to assess the screed drying process, further processing, or the combustibility of wood, our testo 635-2 hygrometer can be used to examine the moisture content in many different construction materials and types of wood. Monitoring drying processes Whether freshly laid screed, or monitored drying of moisture damage, timely determination of the required moisture level will save time and therefore money. Screeds are laid in the in interior works stage, generally after plastering. The flooring and painting and decorating then follow. The drying behaviour is therefore a significant factor in the works schedule, primarily because the laying of flooring depends on this. U-value measurement in old buildings When redeveloping or renovating old buildings, it is crucial to be able to determine quickly if heat is being lost through the windows and walls. Only then can energy costs be reduced and redevelopment measures carried out efficiently. When assessing thermal transmission, e.g. in old buildings in need of renovation, the U-value is one of the most important values. It enables thermal assessment and monitoring of the installed material. 3 temperature values are required for calculating the U-value:
Outside temperature
Surface temperature of the internal wall
Indoor air temperature
A radio probe is needed to determine the U-value; this is placed in position outside. It transmits the readings to the measuring instrument inside. To measure the surface temperature the three wires of the U-value probe are attached to the wall with plasticine. The air temperature is recorded by a sensor located on the probe plug. The measuring instrument testo 635-2 automatically calculates the U-value from the three values and shows this on the display. The advantage: there is no need for manual calculation; the result is quick and accurate. In The Box
