Pirani Vacuum Gauge Super Stars Backlit LCD

Description

Product Overview

The ST‑VG90 by Super Stars is a professional‑grade Pirani vacuum gauge designed for technicians who demand speed and accuracy. It measures vacuum from 0.1 Pa up to 99,999 Pa (0.75‑740,000 micron) using a high‑sensitivity Pirani sensor. The compact pocket‑size body (5.43 × 2.36 × 1.1 in) houses a bright backlit LCD, four pressure units (Pa, mBar, mmHg, Micron), and a smart alarm that triggers both audible and visual alerts when a preset vacuum level is reached. Powered by three AA batteries (included) with an automatic power‑off feature, the gauge stays ready for long field sessions.

Usage

Designed for HVAC system evacuation, refrigeration leak testing, and general industrial vacuum monitoring, the ST‑VG90 excels in tight spaces and low‑light environments. Technicians can quickly switch units to match project specifications, set alarm thresholds to avoid over‑evacuation, and rely on the durable housing for daily field wear. Compatible with vacuum pumps of 5 CFM or higher, it provides stable readings for both routine maintenance and advanced diagnostics.

FAQ

What battery type does the gauge use and how long does it last?

The ST‑VG90 uses three AA batteries, included with the unit. With the automatic power‑off and low‑power backlight, a fresh set typically lasts 150‑200 hours of intermittent use.

Can I use the gauge with any vacuum pump?

The gauge is calibrated for pumps delivering 5 CFM or higher, ensuring stable pressure readings during evacuation. It works with most standard portable and bench‑top pumps.

How do I set the alarm threshold?

Press the alarm button, rotate the unit selector to the desired pressure unit, and use the +/- keys to set the target value. The buzzer and LCD icon will activate once the measured vacuum reaches that level.

Is the device waterproof?

The gauge is splash‑resistant (IP54) suitable for typical workshop conditions, but it should not be submerged or exposed to direct water jets.

What warranty does Super Stars provide?

All ST‑VG90 gauges come with a one‑year limited warranty covering manufacturing defects and calibration accuracy, backed by our technical support team.
