Product Details

1. Product Overview

APSL Type 312 SeriesPrecision Digital Pressure GaugeIt has the measurement functions of pressure and room temperature, can integrate dual pressure modules, and can calibrate pressure transmitters, pressure switches, and pressure gauges. It uses standardRS232Can be connected online for verification, data processing, printing verification records and verification certificates.

It is very suitable for field and laboratory use. It can be connected to a fully automatic pressure calibration bench as an external pressure module, and can also be connected to various pressure sources to form a complete pressure calibration system.

It adopts advanced micro-power components and unique software processing technology, and can truly and continuously measure pressure values. It has a backlight function, which is clearly visible in dark environments.

The APSL type 312 series dual-range precision digital pressure gauge can have 2 built-in pressure modules, doubling the pressure coverage range. During use, it can reduce the number of times to replace the precision digital pressure gauge, reduce the probability of pressure sensor damage due to overpressure, and when used in the field, it can reduce the number of gauges by half, making it convenient to use, cheap and good. The dual-range precision digital pressure gauge can achieve perfect coverage of the calibration range. When verifying pressure transmitters, there is no gap in the middle. The same number of precision digital pressure gauges with the same range can cover a wider range of ranges.
