Wireless Digital Vacuum Gauge 50163B-72

50163B-72 - Dry-Battery-Digital-Vacuum-Gauge

DETAIL

✔ Overview

This product, built with Pirani professional vacuum sensor, can precisely measure the vacuum

level for getting the information of best dehumidification and removal of foreign matter (such as

oil, impurities, etc.), obtaining the best status for charging refrigerants, real-time monitoring and

measuring the leakage to the vacuum system, distinguishing the vacuum pump quality.

✔ Features

1/ Operated by mobile phone.

2/ Long wireless range to monitor vacuum.

3/ Smart vacuum pump will shut off automatically

after reaching the pre-set vacuum on the vacuum gauge.

4/ Auto power-off.

5/ Higher accuracy sensor

6/ Larger Maximum overload pressure,500psi

✔ Product Description

❶	Micro- USB data port: connected with the vacuum pump, can control the automatic shutdown of the vacuum pump.
❷	Display: vacuum, unit, power, time, connection setting with vacuum pump, LO vacuum alarm mode, HI leak alarm mode, vacuum change rate.
❸	Power Switch: A short press on/long press 1S to turn off the power, press < 1 second to switch the backlight. RUN/UNIT: Specific functions and operations are shown below. ALARM/MODE: Specific functions and operations are shown below. Up and down arrow keys: Switch units, activate HI or LO, set vacuum value to change, switch the 'Vacuum Rate of Change" display and the "Timer" display. 9 Specific functions and operations are shown as follows.
❹	7/16”-20UNF (1/4” SAE)

Battery life indicator	Segments reflect the remaining battery life. Each fragment represents 25% increments. shows its lack of power, Low battery.
Automatic Shutdown Time	Vacuum gauge shuts down automatically: The gauge shuts down automatically after reading Hl-P for 30 minutes
Working environment	Atmospheric Environment.
Other functions	Audible and visible alarm, leak alarm, ERR reminder function, anti-pollution connection accessories, tinning (when the vacuum gauge starts the accounting, the pump will reset and start the timing again as soon as it works; When the time is displayed, short press the unit button will reset the timer and restart the timer. When displaying the leakage rate of/MIN, press the unit button for a short time. The pump will stop working if it has no effect. It will be cleared to zero and start the timing again.
