Testo 400 & 454 Multi-Function Meters / Loggers Testo 400 is the multi-function measuring instrument with which many specialists and professionals in industry and the trades simplify their measuring tasks. testo 400 includes all functions of the - Temperature reference measuring instrument testo 950, e.g. high precision: accuracy < 0.1°C (1/100 resolution), probe adjustment - Humidity/pressure reference measuring instrument testo 650, e.g. complete Mollier diagram. - Using testo 400 you can perform all types of velocity measurements (thermal probes, vane and Pitot tube) regardless of whether in a duct, duct outlet or suction aperture. The measurement of volume flow for the approval of air conditioning and ventilation systems in accordance with VDI 2079, 2080 (in future EN 12599) is easily solved and very easy to use. All conventional types of mean calculation are integrated in testo 400. - A comfort level probe corresponding to DIN 1946 Part 2, DIN EN 27726, ISO 7726 can be connected when measuring ambient air velocity as part of checks on comfort level. - Checks indoor air quality or the air exchange number using CO2 probe (See DIN VDI 1946) - Checks ventilation in underground garages using CO probe - Checks transducers using the mV/mA measurement input - Logs data with date, time and location over long periods using the logger function in the measuring instrument. Equipped for the future The following functions can be upgraded: - The measuring instrument guides you through volume flow calculation and calculates, for example, immersion depths, number of measurement points... - Calculates inaccuracies on location - Standardised protocols are easily printed out - Memory upgrade for approx. 500,000 readings (optional) - ...

Testo 435 Compact Pro Multi-Function Meters / Loggers Testo 435 - The measuring instrument for ambient air conditions, for assessing Indoor Air Quality and adjusting and inspecting VAC systems. testo 435-1 is an affordable introduction to measurement engineering for ambient air conditions. The new IAQ probe measures Indoor Air Quality by measuring CO2 level, air moisture and air temperature. Temperature and humidity measurement is integrated in the new thermal probe. In addition, it is also possible to connect additional temperature probes. Readings from up to 3 temperature probes can be displayed in the clearly laid-out measuring instrument display; data transmission is radio-controlled, therefore wireless. Measurement data is printed on site on the Testo printer.
