SYT-2000J Precision digital pressure gaugeDetailed product description：

The SYT-2000J precision digital pressure gauge (hereinafter referred to as the instrument) is mainly used for precision measurement of pressure or as a measuring standard instrument for calibrating various pressure gauges, pressure gauges, pressure sensors, pressure transmitters, etc. The precision digital pressure gauge in the medium and high pressure range is used to replace the standard piston pressure gauge for calibrating various working pressure instruments. The instrument has 1-9 measurement data storage and data query, as well as temperature display functions. It can reduce labor intensity, improve work quality and efficiency. The instrument is equipped with an RS232 port for networking with a computer.

The instrument uses high-precision pressure sensors as sensitive components to detect pressure. The instrument is equipped with Kpa and millimeter water column pressure, and automatically compensates with a microprocessor. The instrument has three levels of numerical stability function for sampling. This ensures the high stability of the instrument's long-term zero point and accuracy, as well as the reliability of the instrument.

Usage:
The instrument should be placed on a stable and flat horizontal workbench, and should not be moved during measurement. Check the battery voltage of the instrument. If the voltage is insufficient, it should be charged for at least 2 hours or operated using a charging power source.

Turn on the power, the display screen lights up, and the instrument enters self-test, displaying 9, 8 → 0 in sequence. Then the instrument displays the initial zero position, and the instrument is preheated for 15 minutes. Select measurement type: KPa, or mm water column pressure. If you need to use the storage function, press the query status before use, then press the reset button to clear the data stored in the instrument, and then press the return button.
Pressure connection, the instrument is introduced into the output port with a rubber hose. If positive pressure is applied, the instrument displays pressure data. If negative pressure is applied, a double triangular negative sign appears in front of the display screen data.
