APSL322Wireless Transmission Precision Digital Pressure Gauge
Product Description
1. Product Overview APSL322The precision digital pressure gauge is simple in design and practical in function.
It has the measurement functions of pressure and room temperature, and can integrate dual pressure modules. It can calibrate pressure transmitters, pressure switches, pressure gauges, sphygmomanometers, or other pressure instruments, and can also be used for precise pressure measurement.
It can be connected to a computer via WIFI for calibration, data processing, and printing of calibration records and certificates. It is suitable for field and laboratory use, and can be connected with various pressure sources to form a complete pressure calibration system.
2. Technical Advantages 1) With WIFI or GPRS wireless function, it can form an IoT network.
2) APSL322The model adopts advanced micro-power devices and unique software processing technology, enabling real continuous measurement of pressure values. It has a backlight function, making it clearly visible in dark environments.
3) The APSL 322 dual-range precision digital pressure gauge has two built-in pressure modules, doubling the pressure coverage range. In use, it can reduce the frequency of replacing the precision digital pressure gauge, reduce the probability of pressure sensor damage due to overpressure, and reduce the number of gauges needed on site by half, making it convenient and cost-effective.
The dual-range precision digital pressure gauge can achieve perfect coverage of calibration ranges, with no gaps in the middle when calibrating pressure transmitters. A precision digital pressure gauge with the same number of ranges can cover a wider range of ranges.

1. Product Overview
APSL322The precision digital pressure gauge has a simple design and practical functions. It has pressure and room temperature measurement functions, can integrate dual pressure modules, and can calibrate pressure transmitters, pressure switches, pressure gauges, sphygmomanometers, or other pressure instruments. It can also be used for precise pressure measurement. It can be connected online for calibration via WIFI, process data, and print calibration records and certificates. It is suitable for field and laboratory use, and can also be connected with various pressure sources to form a complete pressure calibration system.
2. Technical Advantages
1) With WIFI or GPRS wireless function, it can form an Internet of Things.
2）APSL322The model adopts advanced micropower devices and unique software processing technology, enabling true continuous measurement of pressure values. It features a backlight function, making it clearly visible in dark environments.
3) The APSL 322 dual-range precision digital pressure gauge incorporates two pressure modules, doubling the pressure coverage range. In use, it reduces the frequency of replacing precision digital pressure gauges and lowers the probability of pressure sensor damage due to overpressure. On-site, it can halve the number of gauges needed, offering convenience and cost-effectiveness. The dual-range precision digital pressure gauge achieves perfect coverage of calibration ranges, with no gaps when calibrating pressure transmitters. With the same number of ranges, it can cover a wider range of pressure values.
4) Through a WiFi router, hundreds of gauges can be networked. Dedicated software can collect data from all gauges and print data at scheduled times. Nodes can be self-edited.
