Description
The replacement hood 305 x 1220 mm for testo 420 is a long-format interchangeable measuring hood for volume flow work on elongated ventilation outlets with the testo 420 system. To ensure correct measurement results a minimum outlet size of 335 x 335 mm should be observed; this 305 x 1220 mm hood addresses rectangular or linear grilles that fit that requirement along the longer axis. It belongs to the accessory programme for the testo 420 volume flow hood and lets users match the capture area to different diffuser geometries during HVAC balancing, commissioning and verification. Delivered as one piece from manufacturer Testo, the hood has a net weight of 0,9 kg and mounts to the compatible instrument base for immediate use. Service engineers, facility managers and laboratory teams can stock this size as a spare or as a complementary format when several outlet shapes appear on the same site. Compact packaging supports easy storage and transport between measurement locations.

A digital thermometer is a display plus a sensor. The resolution on the screen can be finer than the accuracy. The stated accuracy and the calibration point are what the number is worth. The probe type has to be the one the meter expects.
A thermometer reports a temperature. A liquid-in-glass thermometer is a calibrated column. A digital thermometer is a sensor and a display, and the sensor, not the display, is what is calibrated. An infrared thermometer reads a surface and depends on emissivity. A data logger stores the reading over time. Without a stated uncertainty and a calibration point, the number is only an indication. The scale is maintained by the BIPM and compared by EURAMET. Accreditation is BELAC.
