Extech EN300 5-in-1 Environmental Meter
Measures Humidity, Temperature, Air Velocity, Light and Sound
One of the standout features of the TESTO 350 Control Unit is its intuitive user interface, which simplifies the process of setting up and operating the exhaust gas analysis system. The large, backlit display provides clear, real-time data, making it easy for technicians to monitor key parameters such as gas concentrations, temperature, and pressure. This ensures that emissions measurements are both accurate and easy to interpret.
The integrated low-friction vane wheel improves air velocity accuracy, providing measurements in feet per minute, miles per hour, meters per second, kilometers per hour, and knots. A precision thin-film capacitance humidity sensor ensures a rapid response for humidity readings. The device also features a built-in thermistor for measuring ambient temperature, with temperature measurements up to 2372° (1300°C) achievable using a type K input.
For light measurements, a precision photodiode and correction filter are utilized for cosine and color adjustment. Sound level measurement meets IEC 61672 class 2 standards with A frequency weighting and a fast response time. The package includes a type K thermocouple probe, a carrying case, and six 1.5V AAA batteries.
