Used TESTO 635-2 #9375386 for sale

TESTO 635-2 is an example of electronic test equipment used for measuring temperature, humidity, and air pressure in scientific and industrial environments. This handheld device is designed for reliable, fast, and accurate readings, with a wide range of features that make it an excellent tool for testing environments. 635-2 provides multiple measuring points for a variety of air parameters including temperature, relative humidity, air pressure, dew point, wet bulb temperature, absolute humidity, and enthalpy. Its built-in sensors and probes are designed to detect any accuracy errors or hysteresis even when temperature readings are taken in remote or difficult-to-access places such as chimneys, flues, and combustion chambers. The device is equipped with a large, bright LED display that allows for easy readability, even in poor light conditions. Furthermore, the display has auto-detection of temperature and humidity at any given time. TESTO 635-2 supports professional-level calibration, allowing the user to record calibration data and store it for future use. This facilitates accurate testing even if the ambient air is unstable. In addition, an optional precision pump is available for precise calibration pressures up to 15 bars or 214 psi. The device also has the ability to save and store up to 500 readings, and is equipped with an internal memory and PC software capable of creating fully formatted results reports. Furthermore, these readings can be further analyzed and used in trending and logging functions. One of the other features included in 635-2 is an automatic closure of the measuring points after the power is off. This provides overpressure safety for any hazardous areas by preventing unrestricted gas flow when the device is not in use. To further ensure safety against hazardous areas, the device is made with a rugged aluminum housing that is waterproof and designed to withstand harsh environments and temperatures ranging from -40oC to 60oC. In conclusion, TESTO 635-2 is a handheld electronic test equipment that is designed for convenience, ease of use, and accuracy. Its wide range of features, including the auto-calibration, the large LED display, and the rugged aluminum body, make it an ideal tool for measuring temperature, humidity, air pressure, and other air parameters in a variety of industrial and scientific environments.
