Testo 635 2 Humidity-Temperature Measuring Instrument Prl

The testo 635-2 temperature and moisture metre has a number of advantages, including the following:

By measuring and logging the pertinent characteristics, testo 635 2 can assist you in optimising the air conditioning system.

You can use it, for instance, to check the temperature and relative humidity of the indoor air as well as the surface temperatures of the walls and windows.

This can assist you in modifying the ventilation, heating, or cooling settings to create the ideal level of comfort for your clients or staff.

By identifying moisture issues at ceilings and walls, it can assist you in preventing mould growth and damage.

For instance, you can use it to gauge the moisture content and moisture compensation of building materials including concrete, plaster, and wood. This can assist you in locating places that are vulnerable to mould growth or water damage as a result of excessive moisture levels.

Additionally, you may use it to determine whether there is a chance of condensation or moisture by calculating the difference in dew point between the surface of the wall and the air within.By determining the moisture content of the materials, you can ensure their quality.

It can be used, for instance, to gauge the moisture content of wood items like furniture, flooring, or lumber. This might assist you in deciding whether they are sufficiently dry for installation or storage. It can also be used to gauge the degree of material moisture in foods like grains, nuts, and fruits.

You can avoid spoiling or quality loss caused by an excessive or insufficient moisture content by doing this.

In order to avoid corrosion and damage, it can help you keep an eye on the pressure dew point in compressed air systems. It can be used, for instance, to gauge the pressure dew point in pressurised air tanks or pipes.By doing this, you can make sure that the compressed air is sufficiently dry to prevent freezing or condensation, which can lead to rusting or malfunction of pneumatic tools or equipment.

You can use it to measure the HTC value and ascertain the materials’ heat transfer coefficient. For instance, you can use it to calculate the HTC value of insulation materials like mineral wool, foam, or fibreglass. This enables you to assess their thermal effectiveness and energy effectiveness.

Using the Testo 635-2 temperature and moisture metre has some disadvantages, including:

Extreme temperatures lower than -40 °C or higher than +150 °C cannot be measured by it. As a result, it might not be appropriate for uses like detecting extremely low or extremely high temperatures in industrial ovens, cryogenic storage, or metal processing.Due to its little memory, frequent data transfers can be necessary.

This means that if you have lengthy measurement cycles or brief reading intervals, it might not be able to save all of your measurement data. The USB cable or software may need to be connected to your PC or laptop on a regular basis in order to transfer your data.

It has a protection class of IP54, which implies that it is splash- and dust-resistant but not water- or dustproof. As a result, it might not be able to survive extreme weather conditions like dust storms, torrential rain, or snow.

Temperature data logger testo 176 T4 Powerful and long-lasting, the testo 176 T4 temperature data logger can concurrently measure and record the temperature at up to four separate locations. It can measure temperatures between -200 °C and +1000 °C, and it has a super-size memory that can save up to 2u202F000u202F000 readings.

Testo 176 T4 Temperature Data Logger

It also has a wide display that provides quick access to all the necessary information and a backlit display that makes it possible to read the measurements in dim light.

It has a protection class IP65, which means it is dustproof and water-resistant, and an incredibly long battery life of up to 8 years.

Additionally, it includes expert software with an Excel export feature for setting up the logger and performing data analysis.

For temperature monitoring in a variety of industries, including food, pharmaceuticals, biotechnology, metal processing, and industrial applications, the testo 176 T4 temperature data logger is ideal. It can log and measure.

the temperature simultaneously at four distinct locations utilising a range of thermocouple sensors, including type K, T, or J sensors as well as air, surface, or probe sensors. Additionally, it is capable of CFR 21 Part 11 Compliance, demonstrating that it complies with the standards for electronic documents and signatures in the pharmaceutical sector.

The following are some advantages of utilising the testo 176 T4 temperature data logger:

The Testo 176 T4 temperature data recorder is capable of measuring and recording temperatures in extreme ranges, both below -200 °C and above +1000 °C. This makes it a suitable tool for tasks that involve monitoring extremely low or high temperatures, such as industrial ovens, cryogenic storage, and metal processing.

Despite having shorter measuring cycles, this device allows you to retrieve logger data at longer intervals. Moreover, it boasts a larger data storage capacity compared to the Testo 635-2. This feature translates to the convenience of reducing data transfer frequency, saving you time and effort. In addition to traditional USB cable transfer, you have the option of using an SD card for smoother data transfer.

The device’s illuminated display ensures ease of reading in dimly lit environments. This attribute proves valuable in settings like factories, warehouses, and basements where lighting may be limited. With an IP65 protection class, the device is both dustproof and water-resistant. This level of protection equips it to withstand even the harshest weather conditions, including dust storms, heavy rainfall, and snow.

Using has some drawbacks, including

the testo 176 T4 temperature data logger include:

Other than temperature, it is unable to measure any other variables. As a result, it might not be able to offer thorough information on air quality and comfort characteristics like relative humidity, material moisture, or pressure dew point.

It calls for thermocouple sensors, which could be more costly or less precise than other kinds of sensors.This implies that it might result in higher prices or less accurate temperature readings.
It lacks an automatic measurement data backup when the battery runs out or is changed, as well as an easy-to-change battery. This implies that if there is a power outage, you could require assistance from a specialist to replace the battery or risk losing your data.


The testo 635-2 temperature and moisture metre and the testo 176 T4 temperature data logger has been assessed as the two best tools for simultaneously measuring and logging the temperature at four separate locations.

Both devices are compatible with a large selection of add-on sensors and probes that can offer details on numerous aspects pertaining to air and gas measurement. They do, however, also have various features and specifications that may accommodate various needs and tastes.

The testo 176 T4 temperature data recorder is more robust and able to measure higher and lower temperatures, whereas the testo 635-2 temperature and moisture metre is more reasonably priced and small.
