Wireless Precision Digital Pressure Gauge
Overview
The APSL322 Wireless Transmission Precision Digital Pressure Gauge has a clean design and practical functions, measuring both pressure and ambient temperature. It can integrate dual pressure modules to verify pressure transmitters, pressure switches, pressure gauges, sphygmomanometers and other pressure instruments, and it is also suitable for precision pressure measurement.
Via WiFi it supports online verification, data processing and printing of verification records and certificates, making it ideal for both field and laboratory use, and it can connect to various pressure sources to form a complete pressure calibration system. Key advantages:
- WiFi or GPRS wireless capability lets it form an IoT network
- advanced micro-power components and distinctive software processing faithfully and continuously measure pressure, with a backlight that keeps the display clearly visible in dark environments. The dual-range version houses two built-in pressure modules, doubling the pressure coverage—reducing gauge swaps, lowering the risk of over-pressure sensor damage, and halving the number of gauges needed on site while covering the calibration range with no gaps. Through a WiFi router, hundreds of gauges can be networked
- dedicated software collects data from all gauges, prints on schedule, and lets you edit nodes yourself.
