A product overview

1, the precision digital pressure gauge for AC-DC portable instruments to measure pressure at the same time, current can be measured and displayed on the LCD, and 24VDC output is available. Pressure hand pumps are installed on the front panel, making it ideal for field calibration instruments.

2, high-performance microprocessor instrument zero point and linear continuous update, ensures that meters long, the zero point has good repeatability and accuracy and stability, high accuracy.

3, high-performance CPU and the temperature sensor auto meter temperature drift compensation, ensure accuracy under a wide temperature range.

4, low power consumption. After the battery is full, ensuring the accuracy of continuous long working hours.

5, constant current, battery voltage overcharge, and under-voltage automatic shutdown and automatic protection function, ensure that batteries are not damaged by over charging or under pressure, long battery life (for a long time, recharge every three months).

6, under voltage protection functions of the micro-power, ensure that instrument even if the operator was therefore long continuous boot will not damage the battery due to under voltage.

7, range of instrument functions, use of a table, with a variety of display styles, can display both pressure, electric current, pressure, water or pressure, kg and current percentage.

8, Instruments with over range alarm function, when the pressure exceeds the rated full-range + 2500 words, instrument displays OVERRANGE! P And built-in buzzer intermittent sound, pressure exceeds the full scale, stop pressure used to fine-tune, adjust up and down.

When the meter when the measured current exceeds 22mA instrument displays OVERRANGE! I And

And the built-in buzzer intermittent sound that represents the current overrange.

9, software rich in content and operation simple and straightforward.

10, thin-film panels and imported tact switch, fashionable, press the key to long life.

11, LCD back light pressure, the current display, intuitive, clear structure make reasonable. Small size, light weight, easy to carry.

12, installing the front panel pressure hand pump, with a trimmer, drain valve. With the world's advanced level. Pressure source parts and fine grinding, airtight good, comply with IP52 seal standards.

13, can operate directly on the Panel, adjust the full scale.

14, metal case, strong anti-jamming ability, strong and impact resistance.

15, volume tuning, extremely easy to achieve detection fixed pressure.
