Differential pressure measuring instrument testo 526 -1 | High precision (DISCONTINUED)

The testo 526-1 is a high-precision differential pressure measuring instrument with an integrated sensor and a wide measuring range from 0 to +2000 hPa. It can calculate differential pressure with an accuracy of up to ±0.1% measured value.

Provide cover: Differential pressure meter testo 526-1, batteries and factory test paper.

Advantages of the testo 526-1 differential pressure meter

With two inputs, you can choose up to two of the following probes to connect to the testo 526-1:

The integrated test menu in the testo 526-1 enables continuous recording or tightness testing of containers. To record pressure testing tasks, you can use the software (optional order) or print the measurement results directly with the Testo fast printer (optional order).

testo 526-1 with internal memory for up to 25,000 measurement values. Measurement data can be saved individually or as a series of measurements.

You can customize the measurement cycle (0.04 seconds, 1 second to 24 hours) and the number of stored measurement values.
